Noctua is preparing updated versions of its NH-U12, NH-U14S, NH-C14S, NH-D15, and NH-L9x65 CPU coolers. The cooling specialist took the opportunity to showcase the prototypes at their booth. The fifth generation of the NH-U12 will come with seven heatpipes and up to 37 percent more surface area than the previous NH-U12S. The CPU cooler will feature two NF-A12x25 120 mm fans in a push-pull configuration. Noctua also promises excellent memory, case, and motherboard compatibility. The company's next-generation 140 mm U-Type CPU Cooler will be based on its award-winning NH-U14S. Improvements include 30 percent more surface area and seven heatpipes instead of six. The heatsink's asymmetric design will allow for better PCIe clearance and 100 percent memory compatibility when in single fan mode. Noctua will update their 140 mm C-type CPU cooler as well. Based on the NH-C14S, the new iteration will provide improved and quieter cooling performance.Although the NH-D15 is already a powerhouse of an air cooler, Noctua plans to kick it up a notch. The upcoming model will get the heatpipe treatment as well putting the total to seven instead of the six heatpipes on the previous iteration. The additional heatpipe provides up to 16 percent more volume and contact area between heatpipes and fins to further boost cooling performance. Noctua also had a 65 mm low-profile CPU cooler on display. With a footprint of 95 mm x 95 mm, the cooler is based on the NH-L9x65 and employs a NF-A9x14 PWM fan. It's been resdisgned to provide 100 percent memory and PCIe clearance with Intel motherboards, and on most AMD motherboards including the mini-ITX form factor. It will come with Noctua's award-winning SecuFirm2 socket that supports the AM4 socket out-of-the-box.
