> 3 dayVery well build product, excellent, as described, price range expensive but if last as described then justifiable.

Greater than one weekHigh quality cooler, nicely packaged and performance is excellent. It keeps my 5900x running at 67C under full load (PBO off). I used the included fans at first but found them ugly and kinda noisy. So switched to a single Arctic P12 which actually gave almost identical results but with a lower noise output.

11-06-2025Im here to answer the age old question, will this cooler work for a Rosewill 4u server chassis? The answer is yes (in my case, pun intended). Im blown away that you can fit this much cooling in a 4U chassis. A 5950x is easily tamed by this cooler. Keep in mind theres probably a mm of space between the cooler and lid however, fits my needs perfectly.

> 3 dayI bought this to cool a 5800x on an Asus Prime x570 Pro in an NZXT H510i case. Although it may not look like it, the standoffs for the mounting kit do allow ample clearance for the capacitors around the CPU socket. The vertical clearance is also fine; theres about 1/3 to 1/2 inch between the side of the case and the cooler.

> 3 dayI couldnt be happier with this purchase. Mounting took a bit of fiddling, but ultimately this was just a great buy.

> 3 dayThis is a beastly CPU Cooler. Coupled with a Core i7 10700K, my idle temperatures are anywhere between 28 and 33 degrees Celsius. Also, while under heavy load (especially after performing Intel Stress Tests) my CPU does not exceed 64 degrees Celsius. That has a lot to say there. Im glad that I went with an air cooler instead of liquid cooling system. I hope Noctua can follow up with my request and send me replacement brown anti-vibration corner pads; one of the pads on the fan arrived with a rip.

> 3 dayvolevo prendere il dh15 ma siccome è un bestione avevo paura che non ci stava nel mio case, quindi ho optato per questo U12A sempre noctua che dire.. ragazzi si adatta a tutti i tipi di settaggio senza problemi è leggermente più piccolo, quindi più adattivo per venire incontro alle esigenze di noi clienti. Fa il suo lavoro egregiamente! mi raccomando a montare le ventole (MONTATELE PER IL VERSO GIUSTO CON LA FRECCIA RIVOLTA VERSO IL RETRO DEL PC), montaggio semplice ed intuitivo istruzioni in eng ma comprensibili anche per chi non sa la lingua! lo consiglio? SI.
