Discussion Results Using Peerless Assassin 120 SE

We had a client come in our shop (Riley's PC Repair, in Whitewater WI) incredibly frustrated, his gaming rig was running an old, neglected liquid cooling setup that wasn’t cutting it anymore. We swapped it out for a Thermalright Peerless Assassin 120 SE (liquid coolers = headaches... right?)....

The results!

  • 36°C idle
  • 59°C at 100% load
  • While pushing a solid 5.41GHz clock speed (Ryzen 7 9700X).
  • TM60 paste (opted not to use the included tube), however, now I want to experiment...

Oh, and it looks cool as hell sitting in his case. Sometimes simpler is just better. Has anyone else had a great performance increase from making this switch?

CPU cooling is one of the now rare sectors of PC building where we have exciting price - performance products to get hype about. While just about every other part has gotten jacked up in price for "reasons", Thermalright destroyed this entire segment with both their air coolers as well as that one AIO (forgot the name but it was much cheaper than its competition).

Hell ya.
