💡 How to pick a CPU cooler
What to look for:
  • TDP rating must exceed your CPU's TDP
  • Socket compatibility (AM5, LGA1851, etc.)
  • Fits within your case's cooler height limit
💰 Air coolers are reliable and quiet. AIO liquid coolers handle high-TDP CPUs best

★★★★★Not a pc builder but easy to do following the instructions.
Worked great, anyone who has installed something in a case knows it can be cramped so either take the motherboard out of of you have a smaller case ply the fans in first after taking a look at what room you have. It looked like surgery to plug mine in after everything was installed. The only issue was the included thermal paste was very thick, hard to squeeze but at least it won’t run everywhere. So far it cools my i9 just fine, it’s quiet, and the installation wasn’t hard except for the fan plugs. It was in my opinion a good deal for the air cooled option.

★★★★★Great Air cooler for Ryzen 9000 series cpus
Great Air cooling product keeps my 9600x at 5.6ghz bellow 80. The 140 does not seem to perform better than the 120 version so it just looks bigger and the fan above memory will stick up higher toward the door on most boards. But there is more cooling surface area. So 1 thumb up.

★★★★★I does its job
Ive used aios and this keeps my 9800x3d running around 43c idol and 50c under heavy load and the fact that the front fan is actually a 120 helps clear the ram in my b650 eagle motherboard.

★★★★★Unbeatable!
Cools Ryzen 7 and 9 chips even better than my Noctua did, at about one fifth of the price! Very well-built cooler tower, fans are pretty quiet and powerful. Can't go wrong with this one!
