    First of , I haven't been here a long time. Call it a testament to the Toughbook reliability and my increased abilities. I might actually understand *nix a bit after 25 years :)

    Now the issue:
    grep -iv ': starting\|kernel: .*: Power Button\|watching system buttons\|Stopped Cleaning Up\|Started Crash recovery kernel' \
    /var/log/messages /var/log/syslog /var/log/apcupsd* \
    | grep -iw 'recover[a-z]*\|power[a-z]*\|shut[a-z ]*down\|rsyslogd\|ups'

    ~returns,

    /var/log/syslog:Oct 27 09:38:44 kop-CF-30KQPAQ2M kernel: [ 1026.489987] thermal thermal_zone0: critical temperature reached(106 C),shutting down

    oops...

    Okay, now what ?

    Looks like you might be due for a thermal pad overhaul.

    The obvious first, right? Seems to be transmitting a fair amount of heat to the case as it is.

    I've only had to replace them on a CF-29 and very effectively used Fujipoly Extreme 1.5mm pads. Shouldn't be long before someone else can tell you if that would do for a CF-30 or not.

    I've just torn my CF-30 open to do the same. Measuring the thermal pad mine was 2mm thick, the one in the video looks as thick also. I was going to order Arctic thermal pads from Amazon but decided to try the 2.0mm (CPU to Heat pipe block) & 0.5mm (Heat pipe to bottom cover) Panasonic EYG-T Graphite-PAD's instead from Digi-Key (Double heat transfer ability). Can't find much about people using them but I see that they are conductive instead of the typical non conductive style thermal pads. Wouldn't that possibly be detrimental to electrical/static protection? Using a Panasonic product to fix a Panasonic product is nice to say.

    That's it. It's next day shipping so I'll post how it works by tomorrow with a few photos.

    So far so good. The local surplus store donated a parts CF-30.
    I just stuffed a second piece of material from the roached machine on top of the existing pad and bolted it back together.
    A whole lot better than 106 degree Celsius shutdowns :)

    Now back to the 4G32 Mitsubishi....

    Right on, good to hear.

    The new pads worked perfectly for the CF-30 Mk1.

    2mm for the CPU block and 0.5mm for the heat pipe to case. One thing I did notice is the longer heat pipe was not making full contact with the case when screwed down (from factory or bent later).

    After bending the heat pipe just slightly near the cpu block, it now sits flush & making full contact along the bottom.

    I ordered the smaller pads 35mmx35mm and have 1/2 of the uncut pads left after doing my CF-29 mk3 also.
