💡 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

★★★★★Good air cooler
It's doing its job just fine lowering the temperatures. Noise level good and the digital screen is a nice addition.

★★★★★Great Air Cooler
It handles my 9800x3D without any issues. The display looks great.

★★★★★Does its job but measure first
Installation is straightforward with diagrams. Temperature at idle is around 47C with a 9950x3d and 100% load is 81C. Noise level ranges from 38 db (idle) to 55 db (full load). As far as performance, it does the job very well for an air cooler at around 50-60 dollar range. Be aware to measure the height clearance in your case and heights of ram because this cooler is relatively tall at 165 mm due to the display. Also ram heatsink or tall ram can push the intake fan out of the case; you can set the fan as exhaust but it will cost you 1-2 degrees C.

★★★★★Screen is awsome
Works fine ,looks seriously cool. My processor is very low for the cooler but if I install something bigger will update the review. 9600x now. Still going strong, but have little sound problem with smaller Fan, 1200 rpm making some sound. İt is not making any sounds -+50 rpm. My luck 🤞

★★★★★GREAT Air Cooler!
Sits on a 9800X3D and it keeps the CPU at about 65C at load (it's 45C as I write this). It helps that it's winter and the room is 15C. It will hit about 22-25 in this room during the summer, so I'm guessing it won't go over 80C. Be sure to change the software to read "CPU Package" and not "CPU". CPU temps were about 10C too low. CPU Package is more accurate.
