[SOLVED] CPU Overheating for no reason

[Sweaty Piglet]

I was moving my desk and pc and so I decided to clean it up. I took out my aio Kraken m22 and cleaned the radiator and fan. Then when I replugged my computer I noticed I was getting insane cpu temperatures like 83 celsius at idle and under stress it was around 95-118 and then it'd shut off. I maybe figured it was thermal paste and so I reapplied thermal paste to my cpu after cleaning off the old paste with isopropyl alcohol, but my thermals were the same. I tried shaking the aio to maybe get rid of air bubbles in the cooler, and even plugging the radiator 3 pin and fan 4 pin into different headers on my mobo and yet still the problem persists. I looked all over forums and reset my computer, but still no luck. I have a Ryzen 5 2600 , Radeon Rx480 Msi Tomahawk b450 Corsair Vengence ddr4, and idk it this helps but even under low load, my cpu is clocking at 3793 mhz while the default clock speed is 3400mhz. I've tried and i can really use someones help. Please Help!!!

If your AIO cooler is more than 4 or 5 years old, it may need to be replaced, as the fluid level can drop over time. Also, if the radiator is lower than the cpu than can cause problems.

My cooler is probably around 2 years old now, and my radiator is above my cpu and i've tried detatching the radiator from the case mount and holding it above and below the case to see if i can move/shake out an airbubble

Did you look at the cooling system because you were getting funny behavior from time to time and after fumbling with it a bit, you woke it up so it decided to fail? Better monitor your temps because I think your AIO is toast and your system will be if you don't get the processor cooled properly. The Ryzen 5 can be fully cooled by an air system and they are much more reliable than water. AIO and water cooling is $big bucks$ and they fail much sooner than air fans and heat sinks. Fans are really cheap to replace. There is a video on Youtube about water cooling.
I'm biased however. I had an XSPC water system fail catastrophically (bottom of tank just fractured off suddenly dumping water on a case fan which sprayed the RIVE motherboard, GTX 780 video cards and i7-3930k.) I will never use a water cooling system again. $3900 computer turned into a box of junk in a few seconds. Don't get sold on a water cooler unless it comes with a warranty as long as an air system works which is about 10 years that covers the damage that its failure causes. Read the fine print and then think of the worse case scenario: catastrophic failure. Who pays for it?

I think it would be worth the time to try another cooler, maybe try an air cooler just to see if that brings temps down, if it does and you still want liquid cooling then you will need to replace the aio.

What is your PC case?

If you have the clearance for it I suggest throwing away that AIO and getting a NH-U12S or Arctic Freezer 34 eSports Duo instead. It will perform way better than a single fan AIO.
