Think my room temperature has increased +1° and I'm playing the same game all the time + a lot of Google Chrome Tabs / live streams open, never went above 65° ~
and now it goes above 70° with just the game open, even when I'm closing all other open tasks like skype and so on.
These water cooling systems (their fan) seems to be really big, I don't know if they fit into my case.
And another problem i don't like: It seems there are two ways to mount these water coolers:
#1: blow air from inside to the outside (but doesn't it heat up the cooling system ?)
#2: blow air from outside to the inside (cooling the cooling system but heat won't get suck out of the case)
My best opinion would be to have one fan to suck heat out of the case and the water cooling system to suck air inside the case(and cool the water system), but I think i don't have enough space for this option ._. .
Maybe i'm wrong because I never had a CPU water cooler.
I can't test my PC with 4.2 GHz right now, because I'm not at home, but my experience has shown that its about 5-7 degrees higher?!.
