    On my new M2A-VM board, the CPU is about 6 - 10C above ambient, so about 26C atm (Cool'n'Quiet enabled), but the NB and SB heatsinks are about 40 - 60C.
    Is the poor TIM that you mention under these and would some good stuff help? I suppose that temps. aren't high enough to bother. though.

    Well it's the nasty pink stuff on there, I'll let you know what the temps are shortly, just in the middle of doing it now!

    You will almost certainly see a drop in temps if you replace the stock TIM with some AS5 or another good paste. However, if you are not planning to overclock or are quite happy with your current temps, its up to you if you want to go through the hastle to drop your temps or would rather leave it as it is

    Well I've currently seeing a small increase - maybe give it another go soon...

    wow, thats a bit of a surprise! Are you are you applied it correctly and not too much?
    Also, AS7 takes about 100 hours to cure before it reaches optimum, so you see a drop by a couple of degrees over a few days. But I definately wouldnt have expected a higher temp to start off with :S

    yeah. heatpaste on my NB got me down a few degree on my Abit AB9 Pro, or so uGuru reckons. Still think uGuru gives lower than realistic temps. However, something will not feel cool to the touch if its <37* cause thats not really anywhere near your hand temp. 50* water feels pretty hot though as its all to do with the rate of energy exchange so the bigger the change in temp across the surface of your skin, the more you feel it. Different people do have different reactions to heat though depending on the nature of their nervour system and damage caused to that area of the skin in the past (take chefs for example). That said, 39* is not the temp of your NB if it feels noticably HOT. Warm, maybe, but not hot. I'd be a bit concerned if its the heatsink thats HOT as thats a fair bit of distance from the chip; might just mean your passive cooler works very efficiently ofc.

    Not overclocking - running as gently as possible without changing settings in the BIOS.
    Just felt the heatsinks (back of the finger is better than the tip): the CPU is 'cold'; the NB is about 40C and the SB is about 50C (it has a very small heatsink), so no panic!

    If you are fit and heath you should be around 37oC, so touching something 39oC shouldn't feel much different. If something feels warm all you can really say is it is hotter than 37oC, and if something feels cold it's cooler than 37oC
    I kind of disagree with you there, right now my hands are nowhere near 37oC - they're bloody freezing!

    Skin temperature can be lower than body temperature.

    Think I may have a little bit too much on - it's a very small area. I'm not sure how much cooler it can get though - this is heatsink temperature not the chip itself. Maybe a hotter heatsink means it's doing it's job properly...

    Anyhow, I'll shutdown and let is cool, then try with a bit less heatpaste.

    I think recent core2 processors start throttling at about 72 degrees. The CPU starts throttling before the temperature starts to damage the processor. So I am guessing at about 85 you start damaging your processor. Anything below 65 degrees load I would say is safe.
    I think a lot of the heatsink manufacturers are making people get too worried about temps to drive them to buy expensive heatsinks imo, and lots of people are falling into the trap. If you are overclocking, fair enough. But I have seen people buy thermalright ultra 120 extreme to cool a low power chip at completely stock and that is way OTT imo, just to get low temps when they do not even matter as they are nowhere near damaging the cpu...

    Your naked skin temperature is about 20-22C which is why 20C is room temperature - it's a very comfortable temperature for a lightly clothed person.

    A hot bath is probably about 45C, so 39C would feel quite hot. Most people cannot stand water over 55C (they feel 'burned') and 60C is well into teh pain-threshold of most ordinary people (foundry workers/blacksmiths etc. tend to have a higher resistance as either their nerve endings are dead or the signals are ignored).
