    Each cf 29 chip will take about a 10mm square piece of thermal material.
    Early units have 2 chips and later ones have 3.
    So, to do one cf29 you will need 10mm by 30mm thermal material.

    Thank you for the information. I also have a CF30 with cooling problems. Could you shed some light on what is required for it so I can order material for both at the same time?

    Regards,
    George

    I haven't had mine apart yet, no reason too except to put the GPS I have into it this time home. But here is a shot of the motherboard and heatsink to give you an idea.

    So only one chip in the CF30 requires heatsinking?

    Last week I did get my first Toughbook - a CF-29 MK4 with 1.6Ghz (CF-29L3Q71BE).
    After a few hours of useage I found out that my CF-29 is getting to hot because when playing a video on youtube it was around 90 degree celsius :-( (65 degree celsius when in idle mode)

    After searching and finding this thread I decided to get some new thermal pads for my Toughbook.
    Because Iam in Germany I couldnt find here the
    Fujipoly Premium System Builder Thermal Pad - Full Sheet - 150 x 100 x 1.5 - Thermal Conductivity 6.0 W/mK

    frozencpu.com did want around 35$ postage for the pads? that was to much for me ;-)
    I did found some other thermal pad on eBay Germany:
    phobya Thermal Pad XT - Sheet - 100 x 100 x 1.5 - Thermal Conductivity 7.0 W/mK

    After 2 days the Sheet did arrive and I used a Guide from ifixit to open the bottom of my Toughbook.
    I removed the 2 old pads, cleaned the surfaces on the cpu/cpu and the cooler.
    Then I applied new pads to the cpu and gpu (because the pads arent adhesive) and closed the case with the screws.

    The first start was a success :) It did start around 38-40 degree celsius and after some working time it will remain at 50-15 degree celsius...
    Viewing a 360er Youtube-Video will bring the Toughbook to arounf 57- max 68 degree celsius.
    With this art of cooling the GPU and CPU wouldnt throotled and did play the video without getting stuck :)

    The thermal pad is much to big :) and did cost around 24EUR. Now I got pad for around 8 to 10 Toughbooks :) BUT is was woth buying the sheeet because my Toughbook is now running strong :)
