Interesting Core Heat Jumps

post #1 of 3
Thread Starter 
Intro: Quick summery

Just today, I was running my sc2 (starcraft2 and that was it) and noticing it was running a little slow for not having extreme graphics settings. I loaded up my RealTemp and it said my CPUs were running quite hot! ~80-90 C.

Next:

Ok, so I quit the game and decided to surf the net. It was a bit hot in the house so I put the AC on.
I've been monitoring my CPU core temps and they are acting...not right.
One moment it will be ~68 C and then I start a program and it jumps to high ~80's C or sometimes ~90's C! Insane.
I run something as small as iTunes and the thing jumps to ~92C.
There is no way this can be correct!

List of my gear:
MSI P67A-G43 Intel P67 ATX Intel Motherboard
Intel Core i5-2500K Sandy Bridge

Usually:
I have SC2, Skype, and iTunes running together when I'm gaming. Not a whole lot going on but never noticed such hot temps before.

I currently have my computer 3" from the wall and a good space all around it. All fans are working and the grill pieces are off of my case (CM 690IIAdv)
There is no restriction of airflow.

Thoughts?

Edited:
This is a NEW computer. Only built a month ago. Nothing modded.
Stock heatsink. I don't want the heatsink to be the escape-goat here but, could this be an issue because it is only stock?

It sounds to me like the heatsink is loose. Try to wiggle/wobble it. If it can be moved at all, then it's too loose. It needs to be so secure that you can not wiggle or wobble it whatsoever. It needs to feel like it's impossible to move.

All right. Thanks! I'll check it out and see what's going with that.


UPDATE!
Tightening down the heatsink worked! Mystery solved!
Thank you, TwoCables for your help
