For the 3000 series Ivy Bridge water cooling is about the only means of even attempting to OC, there is no air cooling that can get up to RPM before the CPU down throttles due to the shitty way they built the chip
Hence why i say most applications. For the average pc user who games but doesnt oc, after market air cooling will be cheaper, easier to maintain & upgrade, and do what liquid cooling does: cool your shit. Plus for the avg gamer who never tried to oc before or with limited experience, air cooling mods to the case, cpu and gpu are far more simple while getting good temp reduction gains.
A true pc oc enthusiast wouldnt bother getting a 3k series ivy bridge unless they didnt do their research, have money to blow, or have money to blow and want a headache and challenge.
Otherwise they would know what components n hardware works best with liquid cooling and build a rig appropriately.
Anyway, as per thread. Buy cpu heatsink n fan, see if it solves heating issue. If u had stock cpu fan you could at least find out without forking $25-40 whether or not its your liquid cooling n pump or something more fucked up with your components
