Overheating

Hi all, got a bit of a problem, I have an i7 930 (bloomfield) on a P6X58D-E mobo, with a Corsair water cooler, when it's running at stock speed (2.9ghz) idle temps are 23c mobo, 33c cpu, when I run a stabilty test with aida64/prime95 my cpu goes to 85c and the cores all around 99c/100c. the thing is the cores keep dropping to 84c/86c every second or so then straight back to 99c/100c. Is that normal? but the cpu stays the same temp 85c, and the test tells me overheating detected,

when I overclock to 3.6ghz the mobo is 23c, and cpu 48c, at idle, I do the same test and I get the exact same readings!! 85c cpu all cores 99c/100c. All the time this is going on (2.9ghz and 3.6ghz) the pc stays stable i.e never turns off/shuts down.

I was also doing some video editing as well (not when the stress test was running) and again I was getting the same temps, all cores again around the 100c mark but no probs with stability, and they were up to 100c for around 30mins surely that would have fried the cpu, what's going on! :o 

any help would be great.
thanks.

p.s. I also can't seem to find in the bios what temp the pc should shut down when it overheats.

change the thermal paste

I thought about that, but still can't workout why it stays stable?

thanks for your quick reply.

Hmmmm...well I'd recommend you put on some new thermal paste such as the MX-4 and then try your test again. Check if the cooler isn't fault as it shouldn't hit 85C

thanks will do, I'll get back when i've done it.

Ok did it, and the temps are better in idle, don't suppose you know how long to leave it before I do a stability test.

thanks again for all your help.
