I5 2500k Temps a little high?

I built a pc recently and forgot to buy thermal paste. My cpu is i5 2500k and I'm using the stock cooler which still has a little thermal grease on it. Problem is, my temps shoot up to 85c according to ai suite 2 when under load (bf3) I'm guessing there isn't enough thermal grease so it is causing these temps. Anyway, I'll have to wait a week or so to receive my thermal paste and the pc is still operating fine at these temps lol. Is it safe to use for the next week until paste arrives or am I looking at some kinda damage?

yes it is, anything over 90C is worrying but under it is okay

and I hope you know that more thermal paste =/= more cooling, if you apply too much it can actually conduct heat and heat up your components even higher and damage them. It's all about the quality of the grease itself, and the method of applying it so that it fills all the cracks, google "pea" and "line" methods of applying thermal paste, you'll get some very helpful tips on how to best apply it

Probably safe if you go easy on it(web-browsing/emails). Keep playing Battlefield though and your rig may need a respawn point.

Hmm so 85c is OK to use. I said this on a different site and a bunch if people with these mega coolers kept saying I was insane to use it if it was going over 60c on load. I just don't want to burn the cpu out.

Next to water, heat is electronics greatest enemy. That being said, these newer CPU have throttling protections built into them that will force them to drop clock frequency. It isn't the best thing for it. You're playing thermal chicken with your silicon.

I personally wouldn't use it but it should be fine for checking email and web-browsing.

the CPU will be permanently damaged if you go over around 100C for an extended period of time, it's called the meltdown point where transistors melt and bend and become useless, anything above 90C (or maybe starting around 85 ish) your CPU will start throttling itself to prevent it from reaching that temperature, this process (theoretically) does no damage to your CPU but should still be a cause for concern.

After your thermal paste arrives and you've applied it properly, if your CPU never goes over 80C then you don't have a single problem. Refusing to let your CPU go above 60C because it might damage the chip is like not letting your car drive above 2000 RPM because it might shorten the lifespan of the engine...

Thank you :)  I try

I guess i"ll just wait for the paste arrive then. I'll use my iphone in the meantime
