The CPU-390 is a definite thermal and aesthetic upgrade to the excellent CPU-380. Realistically our only gripes are minor quibbles. Yes we would prefer a new prettier and more precise mounting system, but that’s about all we can fault Koolance on. But still the question is whether Koolance has done enough. Previously we had recommended the Heatkiller IV Pro for those who wanted performance at any cost. Then the Raystorm Pro came out as a veritable bargain – for $65 you were within tickling distance of the HK4. Now the CPU-390 comes along at a very similar price but with more accessories (115X backplate and TIM included). Both blocks have very similar performance and so the end decision really comes down to aesthetics which is always in the eye of the beholder.
Those seeking a bargain should continue to look at the Raystorm Pro, but those looking for the best just added another option alongside the Heatkiller IV. Because this is a top performing block where the only thing we can complain about is the aesthetic of the thumb nuts then we feel it’s justified in receiving the Extreme Rigs Gold Award!
Where to buy: Koolance – $80-90
