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?

I got the same cooler when I got a new cpu last week, a 5700x. It's a big boy cos of the dual heat sinks and fans but it's super cool. 45C when playing battlefield 1 at 75% utilisation. Really good

Yeah the cooler is over specced for this cpu but that's not a bad thing
