The Noctua NH-D15 G2 LBC Cooler Review: Notoriously Big, Incredibly Good
When you buy a retail computer CPU, it usually comes with a standard cooler. However, most enthusiasts find that the stock cooler just does not cut it in terms of performance. So, they often end up getting a more advanced cooler that better suits their needs. Choosing the right cooler isn't a one-size-fits-all deal – it is a bit of a journey. You have to consider what you need, what you want, your budget, and how much space you have in your setup. All these factors come into play when picking out the perfect cooler.
When it comes to high-performance coolers, Noctua is a name that frequently comes up among enthusiasts. Known for their exceptional build quality and superb cooling performance, Noctua coolers have been a favorite in the PC building community for years. A typical Noctua cooler will be punctuated by incredibly quiet fans and top-notch cooling efficiency overall, which has made them ideal for overclockers and builders who want to keep their systems running cool and quiet.
In this review, we'll be taking a closer look at the NH-D15 G2 cooler, the successor to the legendary NH-D15. This cooler comes with a hefty price tag of $150 but promises to deliver the best performance that an air cooler can currently achieve. The NH-D15 G2 is available in three versions: one standard version as well as two specialized variants – LBC (Low Base Convexity) and HBC (High Base Convexity). These variants are designed to make better contact with specific CPUs; the LBC is recommended for AMD AM5 processors, while the HBC is tailored for Intel LGA1700 processors, mirroring the slightly different geometry of their respective heatspeaders. Conversely, the standard version is an “one size fits all” approach for users who care more about long-term compatibility over squeezing out every ounce of potential the cooler has.

The Corsair iCUE LINK TITAN 360 RX RGB AIO Cooler Review: Meticulous, But Pricey Corsair, a longstanding and esteemed manufacturer in the PC components industry, initially built its reputation on memory-related products. However, nearly two decades ago, Corsair began diversifying its product line. This expansion started cautiously, with a limited number of products, but quickly proved to be highly successful, propelling Corsair into the industry powerhouse it is today. One of Corsair's most triumphant product categories is all-in-one (AIO) liquid coolers. This success is particularly notable given that their initial foray into liquid cooling in 2003 did not meet expectations. However, Corsair didn’t throw in the towel. Undeterred, they re-entered the market years later, leveraging the growing popularity of user-friendly, maintenance-free AIO designs. This gamble paid off handsomely, as AIO coolers are now one of Corsair’s flagship product lines, boasting a wide array of models. In this review, we focus on the latest addition to Corsair's AIO cooler lineup: the iCUE LINK TITAN 360 RX. This model is similar to the iCUE LINK H150i RGB, but introduces subtle yet significant improvements, including a performance upgrade with an enhanced pump. The TITAN 360 RX continues Corsair's tradition of innovation and quality, seamlessly integrating into the iCUE ecosystem for an optimized user experience. Its single-cable design ensures a clean and effortless installation, making it a standout in Corsair's evolving cooler lineup. Cases/Cooling/PSUs
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. Storage
MediaTek to Add NVIDIA G-Sync Support to Monitor Scalers, Make G-Sync Displays More Accessible NVIDIA on Tuesday said that future monitor scalers from MediaTek will support its G-Sync technologies. NVIDIA is partnering with MediaTek to integrate its full range of G-Sync technologies into future monitors without requiring a standalone G-Sync module, which makes advanced gaming features more accessible across a broader range of displays. Traditionally, G-Sync technology relied on a dedicated G-sync module – based on an Altera FPGA – to handle syncing display refresh rates with the GPU in order to reduce screen tearing, stutter, and input lag. As a more basic solution, in 2019 NVIDIA introduced G-Sync Compatible certification and branding, which leveraged the industry-standard VESA AdaptiveSync technology to handle variable refresh rates. In lieu of using a dedicated module, leveraging AdaptiveSync allowed for cheaper monitors, with NVIDIA's program serving as a stamp of approval that the monitor worked with NVIDIA GPUs and met NVIDIA's performance requirements. Still, G-Sync Compatible monitors still lack some features that, to date, require the dedicated G-Sync module. Through this new partnership with MediaTek, MediaTek will bring support for all of NVIDIA's G-Sync technologies, including the latest G-Sync Pulsar, directly into their scalers. G-Sync Pulsar enhances motion clarity and reduces ghosting, providing a smoother gaming experience. In addition to variable refresh rates and Pulsar, MediaTek-based G-Sync displays will support such features as variable overdrive, 12-bit color, Ultra Low Motion Blur, low latency HDR, and Reflex Analyzer. This integration will allow more monitors to support a full range of G-Sync features without having to incorporate an expensive FPGA. The first monitors to feature full G-Sync support without needing an NVIDIA module include the AOC Agon Pro AG276QSG2, Acer Predator XB273U F5, and ASUS ROG Swift 360Hz PG27AQNR. These monitors offer 360Hz refresh rates, 1440p resolution, and HDR support. What remains to be seen is which specific MediaTek's scalers will support NVIDIA's G-Sync technology – or if the company is going to implement support into all of their scalers going forward. It also remains to be seen whether monitors with NVIDIA's dedicated G-Sync modules retain any advantages over displays with MediaTek's scalers. Monitors
G.Skill Intros Low Latency DDR5 Memory Modules: CL30 at 6400 MT/s
G.Skill on Tuesday introduced its ultra-low-latency DDR5-6400 memory modules that feature a CAS latency of 30 clocks, which appears to be the industry's most aggressive timings yet for DDR5-6400 sticks. The modules will be available for both AMD and Intel CPU-based systems.
With every new generation of DDR memory comes an increase in data transfer rates and an extension of relative latencies. While for the vast majority of applications, the increased bandwidth offsets the performance impact of higher timings, there are applications that favor low latencies. However, shrinking latencies is sometimes harder than increasing data transfer rates, which is why low-latency modules are rare.
Nonetheless, G.Skill has apparently managed to cherry-pick enough DDR5 memory chips and build appropriate printed circuit boards to produce DDR5-6400 modules with CL30 timings, which are substantially lower than the CL46 timings recommended by JEDEC for this speed bin. This means that while JEDEC-standard modules have an absolute latency of 14.375 ns, G.Skill's modules can boast a latency of just 9.375 ns – an approximately 35% decrease.
G.Skill's DDR5-6400 CL30 39-39-102 modules have a capacity of 16 GB and will be available in 32 GB dual-channel kits, though the company does not disclose voltages, which are likely considerably higher than those standardized by JEDEC.
The company plans to make its DDR5-6400 modules available both for AMD systems with EXPO profiles (Trident Z5 Neo RGB and Trident Z5 Royal Neo) and for Intel-powered PCs with XMP 3.0 profiles (Trident Z5 RGB and Trident Z5 Royal). For AMD AM5 systems that have a practical limitation of 6000 MT/s – 6400 MT/s for DDR5 memory (as this is roughly as fast as AMD's Infinity Fabric can operate at with a 1:1 ratio), the new modules will be particularly beneficial for AMD's Ryzen 7000 and Ryzen 9000-series processors.
G.Skill notes that since its modules are non-standard, they will not work with all systems but will operate on high-end motherboards with properly cooled CPUs.
The new ultra-low-latency memory kits will be available worldwide from G.Skill's partners starting in late August 2024. The company did not disclose the pricing of these modules, but since we are talking about premium products that boast unique specifications, they are likely to be priced accordingly.
