sooo, i decided to take the plunge and watercool my current rig. I've finally finished it and after running the pump for a bit it seems to be holding water without any issue. had a bit of an issue to begin with as i forgot to put in the plugs for the graphics card block and it sprayed water when i was priming the system.. ooops. i left everything to dry but sadly my PSU didn't survive as it was mounted underneath the GPU. I've replaced my PSU, and i've plugged everything in and turned it on. system posted and booted fine. my issue is that my GPU according to Speed Fan is running at around 24*c but my CPU is showing on all 4 cores between 40 and 50*c and thats with just booting up and idling. Avast is taking up some CPU percentage but other than that its pretty much sitting there idling So is my CPU cooler not fitted correctly or could there be another issue? I took the old cooler off, cleaned away the old paste and put new stuff on the same as i've done previously.
