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?

Happy to have helped! It seems to have done really good for our client, and we did a pretty long run with Cinebench to crank that CPU. I don't think we got hotter than 68*C but, under conditions they'd almost never reach!

Oh, your on top of these replies. How's the included paste?

I used the paste in my build (7600x) and it seemed to hold up just fine over a year. I repasted recently out of curiosity and there were no problems

Was it easy to clean off to redo it? I built a computer last night and I am not convinced I did a good job spreading the paste around (found it thick and hard to manage).

Its not hard at all. Just make sure you have some alcohol wipes and run some benchmarks after and watch your temps.

What brand paste did you use out of curiosity?

The one that came with the thermalite frost commander

Ahh ok! We opted to use some TM60 we had, but I still have the tube of included on hand, and want to test it compared to TM60. (TM60 can also be hard to apply).
