This popular leading CPU air cooler is back on sale, and performs a tiny bit better than the venerable Peerless Assassin 120 SE.
The ARGB version is also available for a few dollars more:
Thermalright Phantom Spirit 120 SE ARGB, $54.90
As always, if you have a small PC case, make sure you check the dimensions to ensure good fit as this is a chunky boi.
A fan Y-splitter cable is included, so don't fret if you only have one CPU fan header like me.
I recently got a 5700X3D and paired this with the PS 120 SE; when undervolted to -30 across all cores it never exceeds 62°C at max load, and spends most of its time in the 40s and 50s during everyday use and while gaming. I'm using Fan Control to set the fans to 50% speed (~950rpm) and they're very quiet — extremely happy with this.
One of the best CPU air coolers, it beats or matches other coolers that cost the twice the price. Get it if you need one.
