RTX 4090 FE’s Axial Fans Are Also Great at Cooling CPUs

Ever wondered how Nvidia’s GeForce RTX 4090 or GeForce RTX 4080 Founders Edition axial fans work outside of the graphics card? chifel forum (opens in new tab) (via Orlac (opens in new tab)) has the answer. He repurposed axial fans from his two best graphics cards for top-down CPU coolers and shared the results.

The axial cooling fan seemed to keep the forum member’s Core i5-13600KF’s operating temperature 9 degrees Celsius and 5 degrees Celsius lower than the Thermalright TL-C12 and Cooler Master Mobius 120P ARGB respectively during the Cinebench R23 benchmark. The noise level during normal operation was also reported to be lower than other fans. However, the axial fan makes a humming noise at very low RPMs, making it more audible than the other his 120mm and his 90mm he tested.
