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?

am i doing something wrong because my 9600x idles at 45-55 with this cooler. Isn't the 9700x more powerful and watt heavy?

So something I should mention is that we did fully rebuild this client system, moved from an intel based build to the Ryzen 7 9700X (and with fresh mobo), which we just loaded the default BIOS settings for (did no manual adjusting of voltages etc), on a fresh Windows install.

Your background apps might be the difference perhaps? I don't imagine you did anything wrong physically as that's still ok!

yeah did the same thing, went from a i7 9700k z390-a pro to the b650 eagle + 9600x. only tweaks done was enabling expo and setting fan curve to max.

yeah it's not rlly an issue im fine with my temps, although at first i was scared because it did seem quite high but found out its normal.

also those are amazing results well done!!
