Tj Max is 100C - cause for alarm?

Hi,

I've been having this recurring problem - but should I be alarmed?

At least 4 or 5 times a week, my desktop suddenly becomes non-responsive. That is, none of my programmes/applications work or respond at all - though slightly curiously, I can still surf the web. I then have to turn my computer off - as it just freezes if I try to reboot. After that it works fine again - until the next time it becomes non-responsive. And so on.

I am 99-100% certain it is nothing to do with viruses, spyware, adware, malware, etc - as I've ran near endless scans & checks (including online ones) and nothing of any importance is ever found. And when I go to Administrative Tools/Event Viewer, no warnings or alerts are flagged up. In which case, it strikes me as fairly logical to think that it might be something to do with Temperatures and/or Voltages.

Yes, all my fans seem to be whizzing around how they should.

So, I installed Core Temp 0.99.1. On average - and as I write, with the PC having been on for a couple of hours - Core #0 is 30C and Core #1 is 31C - which seems OK to me. However, my "Tj Max" temperature is around 100C - which, to my (albeit non-expert) ears, does sound rather on the high side. Maybe alarmingly so.

Next, I installed SpeedFan 4.34 - and, yes, there is indeed a warning about the Core temperature being 55C. I then enabled Automatic Fan Speed - but nothing seemed to change. And I am uncertain as to how to properly use or configure SpeedFan. I have sent an email to the author of SpeedFan outlining my problem (or potential problem).

Finally, I installed RealTemp 2.70 and it told me this:

Core Temperature - 26C, 27C

Distance to TJmax - 69C, 68C

Minimum temperature - 26C, 26C

Maximum Temperature - 28C, 34C

By the way, all this is happening on XP Home (my 'default' O/S) and I am currently NOT running it Overclocked with the Abit uGuru software - that is, everything is at 'defaults' (including my Graphics Card).

Have you got any tips or advise on what I should do next? If you have, that would be much appreciated!

Anyway, I look forward to hearing from you,

DANNY.

TjMax is the reference point from which Core Temp and other programs calculate the absolute temperature.
Core Temp assumes that TjMax on certain 65nm chips is 100C, RealTemp assumes 95C for most Core 2 CPUs. (That's why you see the difference in temps between the two).
100C TjMax is nothing to worry about as that value represents the highest core temp that can be reached safely before the CPU enables its thermal defense systems.

Thanks for quick reply - though, obviously, I still want to get to the bottom of the mystery of the 'disappearing desktop'!

cheers,

DANNY

Could be a Windows problem in general or some other program is causing it to happen.

can you post a screen shot of task manger?

also what anti virus,anti spyware are your running?

if your sure it anit spyware or viruses. check out hdtune, and run a bad sector scan, as well as a bench mark... post back screen shots too. Also look at the smart scan in hdtune

Hi Imposter

Sorry to be so late with this request, but only just joined the club

You mention a utility called Hdtune. What is this and where can it be got?
