Our take

Based on 3 reviews

All three reviews agree that the Thermalright Assassin X120 Refined SE delivers adequate cooling performance for its price. TechRadar and What Hi-Fi? highlight its low noise and compact, lightweight design, while RTINGS notes its solid performance. Based on their tests, we conclude it is a budget-friendly option with acceptable build quality.

Two of the 3 reviews raise reservations about minor flaws: Tom's Hardware notes flimsy fan clips, while Basic Tutorials points out cosmetic blemishes on the base plate and fins. Electronikz praises the RGB lighting. For buyers, this means the cooler is suitable for budget builds, but those prioritizing premium build quality or flawless aesthetics should look elsewhere.
