W701 thermal putty question

#1 Post by paulgj2 » Fri Oct 11, 2019 9:00 pm

I see in the W701 Hardware Maintenance Manual that "thermal putty" is used between the fan assembly and the video card. My system runs hot and at some point I want to apply fresh thermal paste to the CPU and video card. I am concerned about replacing this putty to make sure that the video card is cooled properly. Does anyone knows what this entails and if I have to purchase a specific part as indicated in the document? (quoted below from page 102)

Note: In ThinkPad W701 and W701ds, thermal putty is used between the thermal device/fan and the video
card. The thermal putty is included in the video card FRU, but is not included in the thermal device/fan FRU.
If once you remove the thermal device/fan, you need to attach new thermal putty on the video card before
you reinstall the thermal device/fan. Order the thermal putty FRU when you service the thermal device/fan.
ThinkPad W700 and W700ds do not have this thermal putty.


Thanks in advance for any info!

I have often wondered whether a small copper plate with thermal paste top and bottom would do a better job than thermal putty. The plate would have to be thick enough to fill the space.

probably, there are also various third party thermal pads available, key is getting the correct size and thickness.
