so i guess the coolant temp should be under 45? and the air blowing out from the rad is 39 too

do u think i should replace the fuzion v2 with supreme or supreme lt? which one is better?

or the fuzion v2 just perform normally considering my room temp and rad temp? because the temp drop down really fast when i stop prime 95(though still get 50 at idle)

really really need your help, thanks
There's probably nothing wrong with your setup. I went through the same thing with a couple of low vid chips. They tend to clock very well but all the ones I've had run really hot compared to other chips. You should also be aware that IBT will heat your CPU well beyond anything you will see during normal use. It's not uncommon to see temps in the 70's even on water. Don't waiste your money on a new waterblock, you'll likely not see more than a couple of degrees difference. Lapping your IHS may help bring temps down a bit.
