Very good bang for your buck air CPU cooler. Better than the ID-COOLING FROZN A620 PRO SE I listed a week ago. Aethetics are slightly worse in my opinion. I did end up going with Thermalright Phantom Spirit myself.
With all CPU coolers, check the dimensions and clearance so that they fit your case and other parts like RAM.
Thermalright Peerless Assassin 120 Digital ARGB Black CPU Cooler for $57.27
If people want pretty ARGB lights and a digital temp display on their dual tower cooler. Slightly worse performance than the Phantom Spirit SE.
Thermalright Frozen Prism 360 Black for $71.92
Those needing a 360 AIO can get this very cheap 360mm AIO CPU Cooler. There are worries as to the longevity of the pump though, no reports yet as far as I've seen. And acoustics are worse than other 360mm AIOs, but thats the corners being cut for a cheap AIO. Gamer's Nexus Review
Agree, it's one of the best air coolers.
