ARCTIC Alpine AM4 Passive - Silent CPU Cooler for AMD Socket AM4, Easy installation and long service life, 99 x 70 mm - Black

Please note that this cooler is only rated for TDP of 45 watts. So it's not supposed to be used on a Ryzen 5 2600. However I decided to take a chance and give it a shot. My Ryzen 5 2600 quickly went up to 95 degrees and throttled to remain relevant. However this is because I didn't have any fans in the case. As a result it heated up the motherboard and the M.2 NVME too. However I have since put a single case fan in, and it only goes at 400RPM so it's dead silent, but it's getting some airflow through the case, and it has since dropped to about 75-80 degrees. Which while warm, is perfectly fine and within operating temperatures. Note this is while gaming on the Witcher 3 and Assassin's Creed Odyssey, not idle (or full load). Results will definitely vary. But I'd say if you have even some airflow through your case, then this is a great CPU cooler due to its silence (so long as you don't mind its appearance).

I actually bought 3 of these fan as I've build machines for myself and family.The passive cooling works and for its price is very well worth. Nevertheless I have added a 120mm fan on top of it for my machine as it's on the go 24/7. For checking emails,facebook and the odd videos on you tube it can be used on its own but for more serious work, I recommend to add additional fans to the cpu or the case.

Paired with a Athlon 3000g, and depending on how you have your case fans set up will cool the CPU to about 35°c running kodiEven running handbrake the temps didn't go above 75°c and cooled down quickly afterwardsIt's a bit of a faff to install but not impossible

Installed in an ITX case with a Ryzen 3200G for a home theatre PC. Temps look good, even under load with a single exhaust fan running slow to keep noise down

Does what it says on the tin

Unsuitable when doing anything but light browsing.
