Very Nice


Quiet - even at full speed the fan isn't majorly overbearing. Quieter than some i've heard.
Superb cooling - My AMD Piledriver 8350 used to idle around 40, its now idling at 29, and, if you look at the individual core temps, its down to 12-18 average, compared to 30 average on air cooler.
Easy to fit - I've never fitted an AIO cooler before, but this was a breeze.

Cons: Software isn't so great, buggy, no ETA on fixes (main bug is doesnt display cpu temps).

Overall, highly recommend.


Kraken X40

Ive had this cooler now for about a week, easy instructions to follow when installing. Considering how hot it is in my flat im pretty impressed. Idle temp about 38,39 and 49,50 under full load. Ive put another fan on but its not great so going to get an akasa viper. Oh yeah, i put this on a bulldozer 8120 and its overclocked to 3.8GHz, could go more but its not stable. Overall impressive.
