Anyone Upgrade Thermal Compound - Artic Silver 5?

Just wondering if anyone has replaced the thermal grease between the heatsink and processor on the CPU with GPU with anything better? I did it on my last notebook and noticed a 3-5 F improvement in my temperatures.
Is the thinkpad setup so that if you remove the CPU fan you will void the warranty? Someone who has opened theres up, please fill in me.
I noticed that you must open the unit to install ram....

Yes, but my machine has ZERO warranty to begin with (assembled from spare parts).
If you have a > 2.0GHz chip it is worth it. If not, don't bother.

I opened up my laptop today and applied the arctic silver 5. For anyone wondering, there is no kind of security tape on any parts of the laptop that would "void the warranty".
The factory thermal grease used on the cpu was already a silver type compound, which is great. But it was heavily splotched on and all squished out of the sides.
I've noticed minimal gains (1-2 C difference), but according to the manual arctic silver 5 requires 200 hours to "burn in".
Also, the GPU and northbridge uses a thermal pad. I tried removing the thermal pads and the arctic silver instead. The GPU barely makes contact with the heat sink, while the northbridge DOESN'T contact at all. I ended up just reusing the thermal pads taking a safety.
I have a T60 with the 2.0 Ghz Core2Duo CPU and ATI x1400.

.
Were the GPU and Northrbridge making contact with the thermal pads before you removed them ?

I'm switching FANs and upgrading to T7200. Will use Arctic Silver 5

Dimitri: What fan are you switching too?
Rwang: Yes, with the stock pad, the GPU and northbridge makes full contact. The pads used is this goupy jelly thing, not the traditional thermal pad that you see.
I ended up reusing both stock pads, since the northbridge could not reach without it.

The Fan in the brand new T60p, that I just got, makes a high pitch noise. I just got another fan, will test it later tonight, see if it just one fan, or all of them suck...
Once Intel T7200 arrives, I'm putting on the thermal crease.
BTW, the best way to clean copper would be alcohol first and then ketchup
