Nice thread, but sadly I have found it because I have been listening to the slow demise of my 15 inch T60's fan for some time.
Yesterday, the fan just stopped, after a violent death rattle.
So I opened up the machine, and removed the HSF. I note the FRU is 41V9932, although I don't understand the difference between this and 41W0467 (see page 61 of the HMM - http://download.lenovo.com/ibmdl/pub/pc ... 844_04.pdf
-, where there is a "compatibility matrix").
I cleaned up the dust as best I could, cleaned off the thermal grease, using a pre-injection swab impregnated with isoproyl alcohol, and applied Arctic Silver 5. Bolted things up again, and the fan did struggle back to life for a while, but I am now getting fan error on boot.
Now I come here and find out about lubrication, and fan replacement strategies. I think I need to do a fan swap at this point, so I have looked at msb0b's illustrated guide (thank you). What I don't understand is what tools I need to cut the aluminium foil tape, and whether it is desirable to do anything to "mend" the cut when putting things back together. What I mean is, is the foil so thin that you can use anything with a blade, e.g. a kitchen knife? I didn't inspect this while I was inside the machine, and I am loathe to go back in before the final fix.
Also, if replacing the fan altogether, are there any non-obvious steps relating to connecting it up - msb0b only discusses lubrication, so disconnection is not addressed. I assume (hope) no soldering of fan wires will be necessary.
Also, I hear the best fans for this purpose may be from the T500 series, and that T61 fans are also good (or is it just the whole T61 heatpipe assembly that is better than that on the T60, and the fans may be no better?). Does anyone know the part numbers I need?
Edit: What about this
, which is all I can find at the moment?
