<div class="IPBDescription">why? how? o_O</div> ASUSProbe says i'm idling at 40*C now, instead of like 33... i recently installed a new heatsink, but it's been idling at 33-34*C for three days... why now? i'm not overclocking, i don't get it..

I wouldn't worry about that. 40 is fine. My CPU idles around 50C, though I need to lap my heatsink and put new thermal grease on. Start worrying when it gets in to the 70s.
Temperature / Humidity of room, the load on the CPU, dust/dirt/hair buildup, possibly wear on the ball bearings in the fans causing them to run slightly slower.. could be anything really...

The new P4s are a lot hotter than the new Athlons.

AMD Athlon 64 +3500.
i reapplied the thermal compound.. the comp booted up and idled at 36, but it slowly crept back up to 40 <!--emo&:angry:--><img src='http://www.unknownworlds.com/forums/html/emoticons/mad-fix.gif' border='0' style='vertical-align:middle' alt='mad-fix.gif' /><!--endemo-->

40 is fine dunno what your getting worried about Zig!
i have a XP 2500+ overclocked to 1.9ghz sits nicely at 40 now but thats with a massive heatsink. Trust air cooling is always the best and coolmaster aquagate sucks!

On to the main question: one reason it could be increasing in temp is the thermal paste. It seems that as yours heats up it is causing it to infact loose thermal conductivity. Or, ya know, your heatsink could just be absorbing its max amount of heat before it gets into a sort of heat equilibrium, as the heat is produced from the processor it is taken away at the same rate. So it seems your heatsinks natural temperature before it reaches this is 40*c.

turns out it was probably just the house temperature. it's nice and cool now, back at 32*C. last night it was all hot i guess, it stayed at 40 until i went to sleep.
