How do you clean off the old thermalpaste when replacing a HSF?

My Thermaltake D-Orb, which wasnt very good at cooling the 1600xp in the first place, has completely gone; so i've ordered a Taisol to replace it. The Taisol comes with a thermal pad, which whilst are often arent reccomended, should be fine for my non-overclocking needs (and anyway its meant to be a relatively good pad).

1. First get a ball point pen or any ink pen. You don't need the pen, you need the pen cap. Use the pointy end to scrape off as much junk as you can. This is very time consuming and tedious but hang in there! Next is:
2. Acetone (nail polish remover). Try soaking the whole heatsink in this stuff for a couple minutes, and it should help a bit. You can do the same with the processor, soak it in this stuff. It won't harm your processor. Once you are done with acetone, move on to:
3. Isopropyl alcohol. This is essentially rubbing alcohol, but it's better to get 99% pure grade. I got my can at <A HREF="http://www.valcoelectronics.com" target="_new">http://www.valcoelectronics.com&lt;/A>. This is for final cleanup. Oh, and get good ventillation or else you will pass out. A fan or room with a tall ceiling will do. No need to go outside.

Throughout this whole process make ardent use of paper towels or coffee filters. These are good as they tend to leave behind much less fibrous material when you wipe things with them and thus tend to pick up more junk, as opposed to tissues, which simply break. Hardcore users will use lint free cloth, but this tends to be quite expensive. Each sheet of lint free cloth can be $20. And in the end, all you do is throw it away anyway.

Others will probably have more things to add to this list. The isopropyl alcohol works wonders though.

:o 

first time i've had a HSF fail on me, so this looks rather more of a job than expected! Excellent idea on the pen cap, and i can nick some nail varnish remover from my sis, but the alcohol, hmm :\ new HSF should arrive tomorrow and want my pc up that afternoon...

how vital is it to remove every trace of old paste from the cpu? Note i'll be using the supplied thermalpad on new HSF (though getting some Artic Alumina for another little job).

I scraped it off with my thumbnail, and then licked my thumb and rubbed it real good, and then cleaned the core off with an old sock (a clean one). Works pretty well, but that whole rubbing alchohol idea is a good one too.

I guess it just depends how much of the paste you have on there. I was mostly concerned with getting the surface that would actually touch the heatsink clean.

i was able just to wipe it off with a tissue, last time i saw a hs removed it reminded me of a sort of cement/plaster mix; this was still viscous. ta for the help :)

Save yourself all the trouble, scratches, hours, passing-out...Use <b>white-spirit/lighter fuel/benzene</b>. In a single wipping move you'll have all the thermal pad removed and your core/HS shinning like a mirror.

Sure but get good ventillation. Benzene is proven to cause cancer in humans. It also causes breathing problems and a host of other biological dysfunctions.

Question:

Okay so that's how you remove thermal paste. What about thermal tape? (From a P4) Do I just peel it off? OR is there a specific way to do it
