    Hello,

    Just a quick question. I have a CF-19 outfitted with i5 core, 2 x 8 GB1600Mhz 1.35V RAM and 480GB SSD + OEM GPS.

    I've been working outside in the sun lately and I am noticing that the toughbook gets mighty hot to touch and the CPU slows down significantly.

    Do you have any recommendations for keeping the toughbook cool?

    I'm not sure if you linked the right thread... but did consider watercooling it... externally.

    It's a very good idea. Just as good as to using a laptop only at night.

    The CF-19 is only passively cooled. So no fan to cool it off. The heat is transfered from the CPU to a heat sink and then the heat sink is hooked to the body that works as a heat sink as well. Make sure you pop up some shade and keep the bottom with a air gap.

    The early toughbook's were black and had some heat problems in the sun all day, that is why they went to a more reflective silver color to reflect some of the heat back and not absorb it. There are some that came factory and other's that have been resprayed. Not sure what color your's is. Also keeping it plugged in while in the sun will build more heat as well.

    Last thing you could do is a internal mod to go with a better thermal pad on the CPU, but I usually only do that if it has deteriorated.

    My CF-19 is factory standard "silver" with black backcover, ports and "grill" around the monitor. I don't think the thermal pad would help really because the toughbook itself get mighty hot and burns my laps if I put them on my laps.

    I did disassemble the CF-19 and considered replacing the thermal adhesive (I think I remember it being adhesive instead of paste) but I decided not to because the heat transfer from the CPU to the casing was certainly not an issue. I may have a look at it again.

    The CF-19 Mk1 and 2 units I have stripped down that far had the thermal pad. I have not had a Mk3 up down to the motherboard yet.

    Was it running that hot before you disassembled it the first time? May not of got a good set between the CPU and the heat sink.

    I don't remember exactly, but I think I opened it up and disassembled because of heating problem 3 years ago. Basically I realized that there is not really much I can do. I mean I could try a higher quality thermal pad but all of the heat transfer components seemed as operational as they can, the case itself heats up as a result.

    I wonder if setting it on a copper or aluminum plate would dissipate heat better. Or maybe even an aluminum fixture or appliance with water inside to absorb the heat. Or an aluminum T shape with pointed bottom to drive in soil and transfer heat.

    This is the only thing I don't like about the 19MK6...HEAT on the bottom. I sat outside one night for 2 hours with it sitting on my legs. Well I had a very light burn mark across my legs.
