Stock i5-2500k Temperature

[Harouls]

Hi guys, I built my PC a few months ago, it's been running great. But I've noticed that when I run a game or something, the temperature will immediately increase at an alarming rate...I ran prime95 and here are the results.

So, erm.....98C? My PC has NEVER frozen or locked up on me, never BSOD'd, never had ANY problems at all...Wouldn't my PC like, automatically shut off in order to prevent any further damage from the cores running at 98C?
Also, when the temperatures get to that level, I don't hear the heat sink's fan increasing at all. As soon as I stop prime95...

It drops back to normal temperatures IMMEDIATELY which makes me doubt it's related to lack of contact between the heat sink and CPU.

Do you guys think it's just giving me false readings?
Thanks.

It will shutdown only if throttling (running at a lower frequency) can't keep it below 100°C.

Also, when the temperatures get to that level, I don't hear the heat sink's fan increasing at all. As soon as I stop prime95...

You have to check/modify the BIOS configuration and also make sure that the fan is connected to the CPU Fan connector. If you need more help, please let us know about your motherboard, CPU and HSF.

Simple way of checking to see if the stock HSF (heatsink/fan) is seated is to reach in and grab each of the twist clips one at a time and pull straight up. If you are able to pull any of them straight up it wasn't seated well you should reseat the HSF with new thermal paste.

Oh wow, one of the push-pins came right out when I pulled it.
I pushed it back in, and now my computer idles at 25C and gets to a max of 45C......Wow........I was sure that the push-pins were properly seated into the mb when I built my PC, I have no idea how that happened.
Thanks a lot for your advice, you probably saved my CPU....I'll pick up some thermal paste and re-seat the heat sink eventually.
