Is it difficult to replace the thermal compounds already in place with arctic silver? I figure that if the chips run a bit cooler, then the fan won't have to work so hard and i'll have a quieter T60. Does this process void the warranty....well it probably does but is it detectable if i do a good job?

it will void your warranty and ruin your chip as i am told

No - not difficult. You may get a strange look from a tech - but I have used it with no issues. Replaced the motherboard - no questions asked for my onsite repairs.

So, you used it, and it crashed your motherboard???

Artic Silver doesn't ruin your chip. It is just a better type of thermal compound.

If you don't use it correctly it could ruin your chip. But if you don't use your car correctly, you could also ruin it.

Ultimately, you could void your warranty doing the goo replacement if you aren't careful. In the end, you will get a better temperature reduction with improved goo, but potentially at a high cost. I've yet to see a unit fail because of inadequate goo from the factory, but I will admit they do run cooler with better stuff.

the real question is, does replacing the stock thermal compound with AS5 make a measurable difference that affects the fan speed?...i am fairily competent in changing cpu in a desktop motherboard, hopefully it will be just as easy.

What makes changing a laptop cpu more difficult is actually getting to the cpu. With a desktop, you just pop off the panel and unlatch the heatsink. Laptops typically require disassembling just about the whole computer. Thinkpads are typically pretty good computers to work on in this respect, so if your compitent with computer repairs, youre fine.

I most certainly wouldn't mind doing this if,
1. It doesn't void my warranty if I do it properly (don't botch the job). I've done it a number of times on my PC, but never on a laptop.
2. There actually is an improvement in temps (more so for GPU temps than CPU temps), but both would be desirable.

Anyone?

If you decide to do it, can you posts berfore/after tpfan control values?

cheers,

I'd be more then willing to do it if my temperatures were too high for my liking.

I haven't even bought a T60/p yet, but I'm wondering, how carefully applied is the thermal goo stock? Do the notebooks use a so called thermal pad, or is it actual goo smeared on by someone? Someone people are overzealous in regards to putting it on and having it too thick isn't the best idea.

my cpu temp idles from 41 - 45 depending on ambient temp. However, the fan speed doesn't seem to change. I want it to spin even slower but i'm guessing i have to drop the cpu temp for this to be possible. Are there instructions online for how to disassemble the cooling assembly?

FWIW, I use Arctic Silver on my desktops.

It is automated, not subject to individual variation. Every Thinkpad heatsink has presicely the same amount of compound (not pad) for the CPU. The GPU portion of the heatsink differs between models and uses a pad.

You do not disassemble the cooling assembly; the heatsink and fan form one sealed unit which can be replaced easily. Instructions are in the on-line Hardware Maintenance Manual.

True for other notebooks, but not Thinkpads. For the T4x series and the T6x series, after removing the keyboard bezel, 3 or 4 screws release the headsink/fan assembly.

How could I know if I'm applying the correct amount of AS5 in the CPU &/or GPU??

The compound is designed to fill air gaps between two potentially uneven surfaces. Ideally, one wants metal-to-metal contact except where the two flat surfaces have microscopic imperfections and do not make perfect contact with each other. It is those voids that the compound is designed to fill. A small fraction of a millimeter is the thinkness one should apply.

I applied AS5 to my T42p, but I've seen the temperature rise about 5-6C, the CPU now rounds about 48-50C and the GPU 55-57C, before was CPU 45-47C and GPU 51-53C

Anyone knows why, and if should I burn-in the thermal compound?

I was playing NFS Most Wanted, and after a 11min chase, the LCD went black, I guess the GPU became too hott.

Any suggestions?

hmmm well i'm pretty sure that AS5 should be better than the stock stuff. Maybe the cooler isn't making good contact anymore. Does anybody have experience applying AS5 in the Thinkpad and yeilded a positive result?

LOL - Negative - I was experimenting with some overclock values on the GPU and the Gpu fried. Not the CPU. The laptop was an a31p not the t60p. Was under MA.

The correct amount is a very thin amount. Just for thermal contact between the CPU and the heatsink. Too much and you might see a rise in temp. Blow off the fan/heatsink/heat pipe with a blow gun. Good to go.

I was having overheating/stability problems with my T41p.

I removed the heatsink, cleaned it, cleaned the CPU and GPU, applied Arctic Silver 5 to the CPU, and a little to the GPU. I did not remove the pink pad.

CPU temperatures at load are between 5C and 10C cooler. GPU is also runing cooler. Fan exhaust is noticeably warmer all the time.

Good for you.

Guess the ambient temperature have a lot to do with the temp readings.

Doing normal stuff (like browsing the Net) the CPU runs @ 50C, the GPU 52C processor at full power.

However, later in the evening the temps raise: 57C the CPU, the GPU 59C. Don't know why. I wonder if I did right to remove the OEM compounds on both CPU & GPU

Let's see how much the temps drop this winter? (After fiddling with NHC CPU Voltaging Values)
