low temps go high, dont know why

[lurker-drop]

i made it rhyme.. nice... anyway
Ok I have a vantec aeroflow on a xp2200+ (1.8Ghz) which i overclocked to 1.9Ghz, vcore 1.625

It was running about 35C idle using the vantec paste that the aeroflow came with...
I figured why not try some artic silver 5? And so I did, i popped it open, clean off the vantec paste, layed a thin neat layer for the as5... and behold my computer started up at around 24C and ended up around 26C idle after an hour...

I was impressed but the tempatures started to climb back up to 35C over a day or two, now it is even higher... at 38C idle...
Recently I upped the Vcore to 1.65 and it jumped up to 40C idle..

Now I just popped the HSF open again and checked the paste, most of the as5 was 'melted' away or something, so I figured thats the problem, so I wiped it clean, applied a little more than last time, and I'm getting the same results...

What's up? I'd figured the as5 should atleast give me a degrees or two lower than the vantec paste... but its giving me higher temps.. why was it so low for a day and then it disappeared?

AS5 takes a good few weeks to settle down, depending on how much u have you computer on- i think its 200 hours of use. I put mine on about 3 weeks ago when i got my new sk7 heatsink, and my temps have suddenly dropped 3-4 degrees in the last few days. At first they were nothing special and i was a bit dissapointed with the new heat sink but its good now. Just give it some time.

yeah, AS5 takes 200 hrs of (full load) use to break in. try looping the [H]ard|OCP UT2k3 benchmark for the CPU for a few nights when you go to sleep, and while you're at school//work.
