okay so for my build i want a closed loop water cooling system. ive narrowed my choices to the h80i, the h100i, or the thermaltake water 2.0 extreme. however, after doing some research, some people are saying that the h100i and the tharmaltake cannot fit in my case. so i would just like some confirmation, and a recommendation of these three coolers (or any others that you think are better).
i also plan on over clocking a i5 4670k to 4.4Ghz, and would like to know if this is possible with these coolers to stay below 75 degrees on load. Thanks!
