Hey guys, I just got the thermal grease compound in the mail today.
I applied it along the top of the heat-sink, and on the 2 thermal pads on the bottom of the fan, I booted up, and mobil meter showed 65 degree's
while playing a DVD, when befor it went up to 89 degrees, little problem though, my DVD's now skip frequently,
could it be possible that it isen't getting hot enough?
thanks.

Hey guys littleupdate, I took out the P3 CPU,and completely wiped off any thermal grease,Put it back in, and Istill have the same problem ,
My DVD's skipp. well I figured mabey it was because I didne't finish the mod, (soldering a 2.2k ohm resistor too the CPU too allow 600MHz)
I had already cut the Speed-step controller chip. so i put the celeron 500MHz back in it, (same problem) so i don't know what happened.
thanks any help would be great.

P.S. can some-one answer me please?

didn't understand you a bit. You get 89 degrees during dvd playback?

Like I said before, your increased heatsink area just gets hotter but heat from it don't go anywhere, so you probably have created your cpu a perfect green house, with no way hot air could get out:(

Hey mantas. thanks for a reply, no-one ever replies when I kneed help, even though i reply theirs. anyway you think it's the thermal grease that i applied along the top along of the heat sink, that is causeing my DVD's too skip?. MAbey i should try replaceing the fan or something hun?
Mobile meter show quite a bounce in tempiture, it jumps up and down slightly when just idle.
Thanks for your help.

It is not possible that your CPU isn't getting hot enough to play DVDs.

What do you get if you measure the CPU speed with a benchmark?

Also, what software are you using to play the DVDs? More recent players require more horsepower than older players.

I have ALWAYS used win-DVD 4, And my DVD's never skipped befor.
it was after I put the thermal grease on. What are bench marks?

I think that typically (standard cooling) most of the heat goes out when fan blows it out. In your case you have more heat sink area outside. It means that heat is collected in these heatsinks, but there is no way to cool it down. your fan blows heat only from the inside of (heatsink), the remaining extra heat ommits itself inside the case, therefore heating up motherboard and other components (cause of DVD skipping).

If you would like to stick to your idea, find a way to blow heat away from your added heatsinks (like i have tried- through PCMCIA slots, or find your own way).
