CPU Overheating under tiny load. Is my Thermaltake Water 2.0 the problem??

I built my new gaming/work desktop just over a year ago and everything worked great. A few weeks ago my computer was running fine until I noticed it was overheating at around 90 degrees. I restarted and stuff seemed fine. It got worse and now is very bad. I have an i7-3930k running at stock speeds. The temps are higher in the bios than in Windows 7. In the bios after starting up the temps climb then stay at 79 degrees. After logging onto Windows it cools down and idles around 54 – 65 (a little higher than it used to). If I do anything even slightly CPU intensive the temps spike up to around 80 – 90 degrees. CAN'T EVEN PLAY MINECRAFT FOR FIVE MINUTES lol. If I stop whatever program is using the processor the temps very slowly cool back down to idle, but this takes a long time (up to half an hour before back to normal).

My Thermaltake Water 2.0 itself seems to be working. The fan runs and my bios says the pump is at the correct rpm. When my CPU is hot, the one pipe is very hot and the other is always cold. The only thing I noticed was that the air coming off the radiator did not feel very warm (at least doesn't seem like it for 80 degree water going in and the coldness of the water going out). I know that the radiator isn't clogged with dust.

I thought it could be thermal paste because I used the stock stuff that came on my cooler. I replaced it with brand new unopened Arctic Silver 5 making sure to apply the right amount. The temps are a few degrees lower now but it definitely did not fix the problem.

I checked and the processor is at the right voltage. I even reset my bios and went through all of the CPU settings. Last thing I can think of is it could be PSU related but that seems unlikely because I bought a high quality AZZA Platinum 1000W. Everything is stock. Could it be the CPU itself?

Any ideas? I would love some help getting my computer back to being usable.

that's probably the cheapest solution, it sounds like you've pasted the CPU well, since a few degrees is what the result should be.

I've never used liquid cooling before but sounds like the heat isn't transferring properly? I'm really not sure in this case, but trying out an air fan couldn't hurt


Unfortunately the processor I bought did not come with one but I could probably buy one to test it.
