Sudden jump in cpu temps

[emtoucan]

Hi all,

I've been running my overclocked rig for about 3 months now with no issue, but suddendly today I got a warning message about my CPU temp which was around 90C.

I have an E6750 overclocked to 3.6GHz which has been running at around 32 - 35 C at stock and around 55 C under load. It's now at 45 - 48 at stock.

Any ideas why the temp would suddenly jump. My HSF is OK and still securely fastened and at full RPM, the case hasn't been knocked. The computer has been on for about 5 hours today before it happened.

I noticed it after I ran a game which crashed on me (possibly due to the temp?).

Any ideas what I should look for. I'm going to remove the HSF and reinstall, but wondered if there was anything else that could have caused this.

Thanks in advance

The air intake's fine, all fans are working OK.

Very strange as there's only myself and the wife at home and I doubt it's been knocked about.

Oh well, I'll reset the fan and see what happpens.

No definately not dust, the PC is clean as a whistle as it get a through clean every month.

I reapplied the TIM and reset the fan and everything is back to normal.

Very strange as the HSF was securely fastened when I took it off.

Oh well, sorted now. I'll just have to keep an eye on it. I've knocked back the overclock a little too for the time being anyway.

Thanks
