does applying thermal paste (arctic silver) to your cpu void your warranty? cus i think the guy who replaced my cpu onsite did not put any thermal paste on and my thinkpad has been runnig hot ever since

You can always clean it up later. I would not run without Thermal Paste. I use Artic Silver on mine.

went ahead and applied arctic silver thermal paste. idle tempretures have dropped by about 16 degress!!! awesome

Could somebody please take some pics of this and write up a short tutorial. I think lot's of people are interested in this and i'll be more than happy to post whatever you write on one of my servers.

Another reason that i am VERY curious about this is because when i lifted up the keyboard on a T42P tghe CPU was completely exposed - There wasnt ANYTHING on it. No cooler or nothing but i never had any problems with it.

But if i can get the temperature to drop that much, then that should make the fan problems with the T43's go away in an instant.

I also would be interested in reading this information. Also...which Arctic Silver product did you use?

I can't see how this would be construed as a warranty violation, provided that no damage is done during the application.

mlykke, what you saw is not the CPU, it looks like its the cpu but its not. i think its one of the intel chipsets. the CPU is under the bronze fan assembly.

aamsel, i used arctic silver 5

Pretty much i just followed the hardware maintanace manuals direction on removing the fan. basically:
-you turn off the system, and remove the battery
-remove the screws from the bottom of the case corresponding to the keyboard and the palmrest.
-remove palmrest and keyboard
-now the fan is exposed. remove the three screws holding the fan down. disconnect the power lead going from the fan to the motherboard.
-this part was kinda of scary. using a flathead screwdriver, you need to seperate the fan from the CPU. Don't move the screwdriver up and down only inwards. please refer to the HMM for diagrams.
- pull the fan up and away from the heat vents
- now the fan is off and the CPU core is exposed. clean off the CPU core and fan of any thermal grease already on it. i just used acetone (arctic silver suggests that you dont use nail polish cleaner even though they contain acetone. you can also use high purity rubbing alcohol).
-next, apply a very tiny amount (less than half a grain of rice) of arctic silver 5 to the cpu core. spread it out evenly the clean edge of a credit card.
- if there is a plastic tap on the thermal compound between the GPU (not cpu) and fan assemply, remove it.
- reinstall fan (dont forget to plug in the power leads), palm rest, keyboard.

And your done!

for more detailed information refer to the HMM and Arctic Silver's website

oh and before you continue, i had serious heating issues. my normal idle temp was around 60!. the guy who replaced my systemboard onsite, did not apply thermal grease properly (most of grease was around the CPU core not on top of it) and he did not take that plasctic tab off the GPU thermal compound. case in point: don't get onsite service if you live around the LAX

I just got some Arctic Silver 5 in yesteday, and will put up pictures of the "install" and before/after temperature readings (perhaps undervolted) hopefully tonight or tomorrow.

Good to know - Was beginning wo wonder why the hell the CPU was exposed like that. Glad to hear it just looks like the CPU

Anyway about the tutorial and especially the readings - Please let us know how it went.
Im pretty interested in seeing the different readings.

I would not care about undervolted readings, just readings after something like X number of loops of X program where the ambient room temperature was within a few degrees if not exactly the same.
My guess is a difference of just a few degrees if it is tested scientifically.
