One Adventurous Way To Keep Your Tablet PC Cool

- Warner Crocker

M4smallWith all the recent news about exploding lithium-ion batteries and the heat they generate, I think some are probably being a little more cautious these days. I’ve seen quite a few folks blogging about changing their habits and not leaving computers on overnight as an example. Tablet PCs are certainly not immune to heat issues. Another related perennial issue with some Tablet PCs has to do with fans that run more than users would like.

Well GBM’s own enterprising Matt Faulkner decided that he wanted to take matters into his own hands in an attempt to keep his fan from running so much on his Tecra M4. Take a look at the job Matt did on his Tecra M4, but I warn you, the pictures at this link are not for the squeamish. I also don’t recommend you try this unless you are stout of heart, (and of course your Tablet PC warranty has expired). Matt is one brave Tableteer.

I am a mechanical engineer, but I don't design computers. I suggest that considerable caution be used in altering the air flow in a Tablet PC. Cooler air discharge temperature, higher flow velocity at fan discharge, or reducing fan operating speed or time is not necessarily good. Short circuit air paths can improve the previous paramters but cause higher temperatures or new hot spots on critical components deep withing the case. Simple intuition or experimenting is not recommended.

Thanks for the comment. You are correct, but after testing flow and temps with my father (who was also a mechanical engineer - with Motorola for 25 years and had lots of equiptment laying around to help in the testing) we felt comfortable with adding the holes.
