DeepCool Adds Vapor Chamber to an Air Cooler: AIO-Like Performance at Air Cooler Reliability
While the market for high-end CPU coolers has decidedly shifted towards closed-loop all-in-one liquid coolers over the last several years, air cooling remains alive and well. Even at the high-end, there are still further improvements and innovations being made, such as DeepCool's vapor chamber-based tower cooler, which was demonstrated at Computex.
Named the Assassin IV VC Vision, DeepCool's design is an advanced concept vehicle that equips a tower cooled with both a vapor chamber in the base as well as has an LCD pad on top for extra flourish. The vapor chamber is said to increase the cooling capacity by 20W, adding a bit more of an edge to an already very powerful tower cooler design.
While we expect this one to come to market eventually, don't be surprised if both vapor chamber and the screen to land on other products together or separately. For example, the massive DeepCool Assassin IV VC Vision has a more compact brother that has a screen and a vapor chamber.
The unit builds on top of the already monstrous DeepCool Assassin IV that comes with seven 0.6-mm heat pipes and can mount up to three 120/140mm fans, depending on installation (one is magnetically attached). With a weight of 1.575 kilograms – almost entirely copper and aluminum – this one is already good enough to cool down even the highest-performing CPUs.
DeepCool is currently trying to figure out recommended pricing for its Assassin IV VC Vision cooler, but the original Assassin IV costs $99.99, so expect the unit with a vapor chamber and a screen to build on top of that.

Intel Sells Its Arm Shares, Reduces Stakes in Other Companies Intel has divested its entire stake in Arm Holdings during the second quarter, raising approximately $147 million. Alongside this, Intel sold its stake in cybersecurity firm ZeroFox and reduced its holdings in Astera Labs, all as part of a broader effort to manage costs and recover cash amid significant financial challenges. The sale of Intel's 1.18 million shares in Arm Holdings, as reported in a recent SEC filing, comes at a time when the company is struggling with substantial financial losses. Despite the $147 million generated from the sale, Intel reported a $120 million net loss on its equity investments for the quarter, which is a part of a larger $1.6 billion loss that Intel faced during this period. In addition to selling its stake in Arm, Intel also exited its investment in ZeroFox and reduced its involvement with Astera Labs, a company known for developing connectivity platforms for enterprise hardware. These moves are in line with Intel's strategy to reduce costs and stabilize its financial position as it faces ongoing market challenges. Despite the divestment, Intel's past investment in Arm was likely driven by strategic considerations. Arm Holdings is a significant force in the semiconductor industry, with its designs powering most mobile devices, and, for obvious reasons, Intel would like to address these. Intel and Arm are also collaborating on datacenter platforms tailored for Intel's 18A process technology. Additionally, Arm might view Intel as a potential licensee for its technologies and a valuable partner for other companies that license Arm's designs. Intel's investment in Astera Labs was also a strategic one as the company probably wanted to secure steady supply of smart retimers, smart cable modems, and CXL memory controller, which are used in volumes in datacenters and Intel is certainly interested in selling as many datacenter CPUs as possible. Intel's financial struggles were highlighted earlier this month when the company released a disappointing earnings report, which led to a 33% drop in its stock value, erasing billions of dollars of capitalization. To counter these difficulties, Intel announced plans to cut 15,000 jobs and implement other expense reductions. The company has also suspended its dividend, signaling the depth of its efforts to conserve cash and focus on recovery. When it comes to divestment of Arm stock, the need for immediate financial stabilization has presumably taken precedence, leading to the decision. CPUs
The Endorfy Fortis 5 Dual Fan CPU Cooler Review: Towering Value Standard CPU coolers, while adequate for managing basic thermal loads, often fall short in terms of noise reduction and superior cooling efficiency. This limitation drives advanced users and system builders to seek aftermarket solutions tailored to their specific needs. The high-end aftermarket cooler market is highly competitive, with manufacturers striving to offer products with exceptional performance. Endorfy, previously known as SilentiumPC, is a Polish manufacturer that has undergone a significant transformation to expand its presence in global markets. The brand is known for delivering high-performance cooling solutions with a strong focus on balancing efficiency and affordability. By rebranding as Endorfy, the company aims to enter premium market segments while continuing to offer reliable, high-quality cooling products. SilentiumPC became very popular in the value/mainstream segments of the PC market with their products, the spearhead of which probably was the Fera 5 cooler that we reviewed a little over two years ago and had a remarkable value for money. Today’s review places Endorfy’s largest CPU cooler, the Fortis 5 Dual Fan, on our laboratory test bench. The Fortis 5 is the largest CPU air cooler the company currently offers and is significantly more expensive than the Fera 5, yet it still is a single-tower cooler that strives to strike a balance between value, compatibility, and performance.

Kioxia Demonstrates Optical Interface SSDs for Data Centers A few years back, the Japanese government's New Energy and Industrial Technology Development Organization (NEDO ) allocated funding for the development of green datacenter technologies. With the aim to obtain up to 40% savings in overall power consumption, several Japanese companies have been developing an optical interface for their enterprise SSDs. And at this year's FMS, Kioxia had their optical interface on display. For this demonstration, Kioxia took its existing CM7 enterprise SSD and created an optical interface for it. A PCIe card with on-board optics developed by Kyocera is installed in the server slot. An optical interface allows data transfer over long distances (it was 40m in the demo, but Kioxia promises lengths of up to 100m for the cable in the future). This allows the storage to be kept in a separate room with minimal cooling requirements compared to the rack with the CPUs and GPUs. Disaggregation of different server components will become an option as very high throughput interfaces such as PCIe 7.0 (with 128 GT/s rates) become available. The demonstration of the optical SSD showed a slight loss in IOPS performance, but a significant advantage in the latency metric over the shipping enterprise SSD behind a copper network link. Obviously, there are advantages in wiring requirements and signal integrity maintenance with optical links. Being a proof-of-concept demonstration, we do see the requirement for an industry-standard approach if this were to gain adoption among different datacenter vendors. The PCI-SIG optical workgroup will need to get its act together soon to create a standards-based approach to this problem. Storage

Microchip Demonstrates Flashtec 5016 Enterprise SSD Controller
Microchip recently announced the availability of their second PCIe Gen 5 enterprise SSD controller - the Flashtec 5016. Like the 4016, this is also a 16-channel controller, but there are some key updates:
- PCIe 5.0 lane organization: Operation in x4 or dual independent x2 / x2 mode in the 5016, compared to the x8, or x4, or dual independent x4 / x2 mode in the 4016.
- DRAM support: Four ranks of DDR5-5200 in the 5016, compared to two ranks of DDR4-3200 in the 4016.
- Extended NAND support: 2400 MT/s NAND in the 4016, compared to the 3200 MT/s NAND support in the 5016.
- Performance improvements: The 5016 is capable of delivering 3.5M+ random read IOPS compared to the 3M+ of the 4016.
Microchip's enterprise SSD controllers provide a high level of flexibility to SSD vendors by providing them with significant horsepower and accelerators. The 5016 includes Cortex-A53 cores for SSD vendors to run custom applications relevant to SSD management. However, compared to the Gen4 controllers, there are two additional cores in the CPU cluster. The DRAM subsystem includes ECC support (both out-of-band and inline, as desired by the SSD vendor).
At FMS 2024, the company demonstrated an application of the neural network engines embedded in the Gen5 controllers. Controllers usually employ a 'read-retry' operation with altered read-out voltages for flash reads that do not complete successfully. Microchip implemented a machine learning approach to determine the read-out voltage based on the health history of the NAND block using the NN engines in the controller. This approach delivers tangible benefits for read latency and power consumption (thanks to a smaller number of errors on the first read).
The 4016 and 5016 come with a single-chip root of trust implementation for hardware security. A secure boot process with dual-signature authentication ensures that the controller firmware is not maliciously altered in the field. The company also brought out the advantages of their controller's implementation of SR-IOV, flexible data placement, and zoned namespaces along with their 'credit engine' scheme for multi-tenant cloud workloads. These aspects were also brought out in other demonstrations.
Microchip's press release included quotes from the usual NAND vendors - Solidigm, Kioxia, and Micron. On the customer front, Longsys has been using Flashtec controllers in their enterprise offerings along with YMTC NAND. It is likely that this collaboration will continue further using the new 5016 controller.

U.S. Signs $1.5B in CHIPS Act Agreements With Amkor and SKhynix for Chip Packaging Plants
Under the CHIPS & Science Act, the U.S. government provided tens of billions of dollars in grants and loans to the world's leading maker of chips, such as Intel, Samsung, and TSMC, which will significantly expand the country's semiconductor production industry in the coming years. However, most chips are typically tested, assembled, and packaged in Asia, which has left the American supply chain incomplete. Addressing this last gap in the government's domestic chip production plans, these past couple of weeks the U.S. government signed memorandums of understanding worth about $1.5 billion with Amkor and SK hynix to support their efforts to build chip packaging facilities in the U.S.
Amkor to Build Advanced Packaging Facility with Apple in Mind
Amkor plans to build a $2 billion advanced packaging facility near Peoria, Arizona, to test and assemble chips produced by TSMC at its Fab 21 near Phoenix, Arizona. The company signed a MOU that offers $400 million in direct funding and access to $200 million in loans under the CHIPS & Science Act. In addition, the company plans to take advantage of a 25% investment tax credit on eligible capital expenditures.
Set to be strategically positioned near TSMC's upcoming Fab 21 complex in Arizona, Amkor's Peoria facility will occupy 55 acres and, when fully completed, will feature over 500,000 square feet (46,451 square meters) of cleanroom space, more than twice the size of Amkor's advanced packaging site in Vietnam. Although the company has not disclosed the exact capacity or the specific technologies the facility will support, it is expected to cater to a wide range of industries, including automotive, high-performance computing, and mobile technologies. This suggests the new plant will offer diverse packaging solutions, including traditional, 2.5D, and 3D technologies.
Amkor has collaborated extensively with Apple on the vision and initial setup of the Peoria facility, as Apple is slated to be the facility's first and largest customer, marking a significant commitment from the tech giant. This partnership highlights the importance of the new facility in reinforcing the U.S. semiconductor supply chain and positioning Amkor as a key partner for companies relying on TSMC's manufacturing capabilities. The project is expected to generate around 2,000 jobs and is scheduled to begin operations in 2027.
SK hynix to Build HBM4 in the U.S.
This week SK hynix also signed a preliminary agreement with the U.S. government to receive up to $450 million in direct funding and $500 million in loans to build an advanced memory packaging facility in West Lafayette, Indiana.
The proposed facility is scheduled to begin operations in 2028, which means that it will assemble HBM4 or HBM4E memory. Meanwhile, DRAM devices for high bandwidth memory (HBM) stacks will still be produced in South Korea. Nonetheless, packing finished HBM4/HBM4E in the U.S. and possibly integrating these memory modules with high-end processors is a big deal.
In addition to building its packaging plant, SK hynix plans to collaborate with Purdue University and other local research institutions to advance semiconductor technology and packaging innovations. This partnership is intended to bolster research and development in the region, positioning the facility as a hub for AI technology and skilled employment.

<p>While we expect this one to come to market eventually, don't be surprised if both vapor chamber and the screen to land on other products together or separately. For example, the massive DeepCool Assassin IV VC Vision has a more compact brother that has a screen and a vapor chamber.</p>

As the deployment of PCIe 5.0 picks up steam in both datacenter and consumer markets, PCI-SIG is not sitting idle, and is already working on getting the ecosystem ready for the updats to the PCIe specifications. At FMS 2024, some vendors were even talking about PCIe 7.0 with its 128 GT/s capabilities despite PCIe 6.0 not even starting to ship yet. We caught up with PCI-SIG to get some updates on its activities and have a discussion on the current state of the PCIe ecosystem.
PCI-SIG has already made the PCIe 7.0 specifications (v 0.5) available to its members, and expects full specifications to be officially released sometime in 2025. The goal is to deliver a 128 GT/s data rate with up to 512 GBps of bidirectional traffic using x16 links. Similar to PCIe 6.0, this specification will also utilize PAM4 signaling and maintain backwards compatibility. Power efficiency as well as silicon die area are also being kept in mind as part of the drafting process.
The move to PAM4 signaling brings higher bit-error rates compared to the previous NRZ scheme. This made it necessary to adopt a different error correction scheme in PCIe 6.0 - instead of operating on variable length packets, PCIe 6.0's Flow Control Unit (FLIT) encoding operates on fixed size packets to aid in forward error correction. PCIe 7.0 retains these aspects.
The integrators list for the PCIe 6.0 compliance program is also expected to come out in 2025, though initial testing is already in progress. This was evident by the FMS 2024 demo involving Cadence's 3nm test chip for its PCIe 6.0 IP offering along with Teledyne Lecroy's PCIe 6.0 analyzer. These timelines track well with the specification completion dates and compliance program availability for previous PCIe generations.
We also received an update on the optical workgroup - while being optical-technology agnostic, the WG also intends to develop technology-specific form-factors including pluggable optical transceivers, on-board optics, co-packaged optics, and optical I/O. The logical and electrical layers of the PCIe 6.0 specifications are being enhanced to accommodate the new optical PCIe standardization and this process will also be done with PCIe 7.0 to coincide with that standard's release next year.
The PCI-SIG also has ongoing cabling initiatives. On the consumer side, we have seen significant traction for Thunderbolt and external GPU enclosures. However, even datacenters and enterprise systems are moving towards cabling solutions as it becomes evident that disaggregation of components such as storage from the CPU and GPU are better for thermal design. Additionally maintaining signal integrity over longer distances becomes difficult for on-board signal traces. Cabling internal to the computing systems can help here.
OCuLink emerged as a good candidate and was adopted fairly widely as an internal link in server systems. It has even made an appearance in mini-PCs from some Chinese manufacturers in its external avatar for the consumer market, albeit with limited traction. As speeds increase, a widely-adopted standard for external PCIe peripherals (or even connecting components within a system) will become imperative.

The Endorfy Fortis 5 Dual Fan CPU Cooler Review: Towering Value Standard CPU coolers, while adequate for managing basic thermal loads, often fall short in terms of noise reduction and superior cooling efficiency. This limitation drives advanced users and system builders to seek aftermarket solutions tailored to their specific needs. The high-end aftermarket cooler market is highly competitive, with manufacturers striving to offer products with exceptional performance.
Endorfy, previously known as SilentiumPC, is a Polish manufacturer that has undergone a significant transformation to expand its presence in global markets. The brand is known for delivering high-performance cooling solutions with a strong focus on balancing efficiency and affordability. By rebranding as Endorfy, the company aims to enter premium market segments while continuing to offer reliable, high-quality cooling products.
SilentiumPC became very popular in the value/mainstream segments of the PC market with their products, the spearhead of which probably was the Fera 5 cooler that we reviewed a little over two years ago and had a remarkable value for money. Today’s review places Endorfy’s largest CPU cooler, the Fortis 5 Dual Fan, on our laboratory test bench. The Fortis 5 is the largest CPU air cooler the company currently offers and is significantly more expensive than the Fera 5, yet it still is a single-tower cooler that strives to strike a balance between value, compatibility, and performance.

Kioxia Demonstrates Optical Interface SSDs for Data Centers
A few years back, the Japanese government's New Energy and Industrial Technology Development Organization (NEDO ) allocated funding for the development of green datacenter technologies. With the aim to obtain up to 40% savings in overall power consumption, several Japanese companies have been developing an optical interface for their enterprise SSDs. And at this year's FMS, Kioxia had their optical interface on display.
For this demonstration, Kioxia took its existing CM7 enterprise SSD and created an optical interface for it. A PCIe card with on-board optics developed by Kyocera is installed in the server slot. An optical interface allows data transfer over long distances (it was 40m in the demo, but Kioxia promises lengths of up to 100m for the cable in the future). This allows the storage to be kept in a separate room with minimal cooling requirements compared to the rack with the CPUs and GPUs. Disaggregation of different server components will become an option as very high throughput interfaces such as PCIe 7.0 (with 128 GT/s rates) become available.
The demonstration of the optical SSD showed a slight loss in IOPS performance, but a significant advantage in the latency metric over the shipping enterprise SSD behind a copper network link. Obviously, there are advantages in wiring requirements and signal integrity maintenance with optical links.
Being a proof-of-concept demonstration, we do see the requirement for an industry-standard approach if this were to gain adoption among different datacenter vendors. The PCI-SIG optical workgroup will need to get its act together soon to create a standards-based approach to this problem.
