A bit of a mixed bag this cooler it does the job really well but a few issues. Right so overall i am happy with this 240 aio, it beats my artic 34 esports duo air cooler by about 10c on average but cooler master have been extremely tight on quality of some things. To the bad, 1 of the included fans was VERY annoyingly making a grinding sound from the centre bearing after about 2 weeks use, the pipes from pump to rad are very thin and VERY plastic, the pump gets loud when set above 85% speed. Now the good keeps ryzen 5 3600 running pbo and auto ac under 55c in all my games with idle around 28-29c, with pump set to 85% and fans swapped for a pair of amazing artic bionx p120 hsp fans this runs dead quite. I cant complain as got it in a sale for alot less then the normal 50 quid but at the full price i would say look at the gamemax aio, much better quality for the same price.
