420 radiator

Written By dan on Sun 3rd Jan 16, 20:28

Came quick I was well informed of what was happening. Bought this to go in my corsair 750d it just about fits width wise with the ports towards the rear of my case. Fittings included ect . All in all good temps on my cpu and now I've got a monster rad I can run 5ghz all day long with safe temps.

Beautiful but fragile

Just got this so haven't been able to try it out in action, but I must say this is a beautiful little radiator. The matte black sheen is (imo) much better than the US speckled variant. From various tests I already know it will perform well for me.
The cons then? The packaging was super tight and it was impossible to get the radiator out without practically ripping the box apart. The black color is also super delicate, the slightest thing will s****e it off and leave bare metal (It's already bare on the sides from sliding it into and out of the case just once). The short mounting screws where on the short side, my case had rubber fittings in the mount holes to dampen vibrations, but the provided screws were too short to mount the radiator with them in. The longer ones will also be too short with any form of gaskets etc (with standard 25mm fans).
Other than this I really like this radiator and is happy with my purchase.
