Ive got a few issues with a CPU overheating, i have an AMD FX 8320 CPU cooled by a Corsair H55 all in one water cooler, well allegedly its cooled by that device, all has been running well for quite some time, but now i keep getting warnings about CPU temperatures via ASUS AI suite2, using that same app the average temperature when idle is around 60C, going up to 75-80c when web browsing/watching youtube etc. If i'm doing anything intensive the temperature sky-rockets up to 85C and my pc just shuts off immediately.

I've taken the fans off, cleaned out all the dirt and dust as well as taking the pup off the cpu, cleaning off the old paste and re-applying but its made no difference, the only thing ive noticed is a slight sound, a bubbling noise almost like chips frying every now and again, and an odd whirring noise from the pump.
when its making the noise the temps shoot up, if i hit it ( gently) with the back of a screwdriver the noise stops for a while and temperatures go down

any pointers ?
 
thanks, disabled something called Qspeed, but it made no difference.
Also tried running the pump direct from the PSU 12 volt out

one odd thing, if my PC is on its side it takes longer to heat up and only the bottom part of the radiator gets warm, the tubes get warmer the closer they get to the pump

edit: vertical stood uprigth CPU temperatures get to 70C+ and theres a slight gurgling noise, on its side temps sit at 46C
