Verdict

DeepCool Castle 360EX

7.9 / 10 Expert Rating

A solid value-tier 360mm RGB AIO, worth buying on sale but generally outclassed by DeepCool's own newer LT720 at similar pricing.

Thermalright Peerless Assassin 120 SE

9 / 10 Expert Rating

The best cooling-per-dollar in air cooling right now.
