Noctua NH-CS14

I used this on a 65w CPU in orde to make a silent PC. Adjusted the fan curve so that it only goes above 1000RPM at 75C and it almost never does that - completely silent operation. This is really good for silent PC building if you have the space for it in your case.

As always with Noctua fans you get great cooling and super quiet. My Asus Rampage needed the fan sensor setting to ignore as when the pc booted it wasn't spinning at even the lowest 200rpm setting the bios monitor offered. Once up and running idling it sits about 600rpm (pwm). When gaming the fan is quiet (the fan in the gpu makes more noise so you cant actually hear this fan). My idle temp has dropped from 42-44 to 33-35 - impressive (previous fan was 120mm not 140mm). I had to go for this particular heatsink due to vengeance RAM so tall. Cooling a Xeon 3.5ghz 6 core chip that has a 130w tdp. I know the Noctua fan's are more expensive than others but to be honest all my pc's have them in now as I just love the low noise.

So my rig is sitting in a custom 4u server case with 3 140mm fans at the front with a high flow 120mm as exhaust. Pc is in a server rack at current time of testing was at 25 deg ambient temperature. Ryzen 3700x OC on all 8 cores @4.2Ghz With the stock Wraith cooler with 3 minutes of cinebench i was hitting 84/85 deg. With the noctua i was hitting 76 deg. the wraith would of been screaming as where can barley hear it (noise not an issue to me its in the garage) Idle temps stock 45 deg, Noctua 33 deg (this is with both fans set to max) Hope this helps with someone with a similar setup to me

I liked this cooler very much, but it only performs well under certain environments. The cooler only works well when put in a system where the case exhaust runs parallel to the fans on the C14S. If intake and exhaust run perpendicularly to it, it can make temperatures significantly worse due to bad internal air turbulence. The one I got also came with some manufacturing defects, like bent heatsink fins. Although I am returning mine, I would still recommend the product for what it is.

Easy to install after unscrewing motherboard from case. Much quieter than stock fan and knocks a good 10 degrees off operating temperature in comparison. It has no trouble keeping my overclocked Intel 4790k cpu cool and the down blowing fan keeps the RAM and other components cool.
