Noctua's products are known for their quality. This is no comparison to the low price that has developed from the Asetek AIO. If you have a case with great airflow and space, get one. It will never leak, the pump will never fail, and it also runs quieter. The mounting system is the best in the business. Much better than an inherited misfortune. I have one in a Phanteks P600s case with an open mesh front panel. It cools the RYZEN 3950x. If you can handle this cooler, ignore all the talk about recommended liquid cooling. I use 4 Noctua NF-A14 PWM case fans, 3 for intake, 1 for exhaust. These case fans run at 550 RPM and mine is maxed out at 1000 RPM. With the D15, I set the idle speed to 650 rpm via PWM. Under heavy loads, it reaches a maximum speed of 1200 rpm. NOTE: I ONLY TURN ON THE CENTER FAN. (1 FAN) This setting is hardly audible in idle, at full load with my configs it is very quiet. Just a slight breeze. My temperatures are something like this: Idle: 31ยฐC (75ยฐF ambient) Cinebench 20 minute cycle: 71ยฐC Gaming for 3 hours Division 2 everywhere, Max Ultra: 55ยฐC Aida 64 stress test, all checkboxes checked (stressed also graphics processor, unrealistic test): 82cPrime95 small FFU for all cores for 20 minutes (maximum heat): 72c. These numbers are on par or even better than some of the larger AIOs. Best of all, it's quieter and more reliable. I use Coolermaster Mastergel Nano. like thermal paste. This improved my temperatures under load by about 6 degrees compared to the supplied noctua thermal paste. If you can mount this monster in your hull and feed it cold air, ignore the AIO. These feel like cheap toys compared to this Austrian refrigerated monster. RECOMMENDED x1000!
