Slow climb in temps

For the last week or so, I have had a strange case of rising processor temps.
I turn it on, boots fine, runs good, then after about an hour, the processor temp begins to slowly rise. The case temp does not change.
This computer has always settled in with a temp around 36-37C. This is doing e mail, scanning the web, and Folding. Now the temp starts at 36, rises up to ? I've let it climb to 43. But if I reboot, temps falls back to 36, and never rises above 40, even while playing games, Folding running too.
Any thoughts?
Thanks;

    When did you last clean the heatsink?

    It's been about 3 weeks. I just looked at the HS, no major dust. But I'll give it a cleaning, and see what happens.
    Thanks Geeky1

    Second the motion. :thumbsup:

    BTW: You're not really cleaning it unless you remove the fan and really get in there. The fan itself conceals a nice layer of crud which may not be obvious just by taking the side off the case and hitting the HS with a few bursts of canned air. :eek:

    Well, I cleaned things out. It made a small drop in idle temps, but then the temp went right back up. I rebooted when it made 40C. and it's now running 37.
    I don't understand why the reboot drops the temp. Unless there is something wrong with the Abit temp monitor

    It's possible. Try switching to MBM5 (http://mbm.livewiredev.com). You can't run both MBM and Abit's utility at once, tho; that will also give you weird readings.

    Did you also clean and reapply the thermal paste?

    Yes, Virtues, a nice thin layer of Arctic Silver.
    Geeky- I installed MBM5, and after a few sudden crashes, because of the conflicts with the Abit monitor. (and you told me about it , too :doh: ), the temp settled out at 38. Let it run for a couple of hours, then rebooted. And it settled at 36 :-/
    So, it's better (I think).
    But I do like MBM5 better than the Abit monitor. So, I guess I learned something. Since it doesn't seem to be a critical issue, and the fix is quite easy, I can live with it.
    Thanks everyone for your time :thumbup

    IF you want to really study the thing, look at the logging features in MBM 5. I keep my interval log at about 15 or more minute interval log entires, 1000 entries max. Then I log case temp, core temp, voltages, and look for situations where core versus case pumps up a LOT suddenly and look for Windows services and AV updating times and things that schedule and see if they are peaking temps by running all at once.

    The high\low log is also neat to see voltage floats, and temp floats. I have it set to poll at about 15 min also, whihc gives me a nice summary, but the interval log gives me better tracking. I run plain text logs here, open them in wordpad, but you can output HTML logs if you want also.

    My Barton box starts about 4 C lower than at full load after 24 hours run time, but it does not go much above that, instead it floats with room temp and case temp at about 12-13 C above case temp. The P4 CPU temp is kinda scary, it is running a good 23 to 25 C above case, but is hyper-stable.
