As featured in the popular MateBook X Pro laptop cooling mods on BradsHacks .com, these pyrolytic graphite sheets have incredible thermal conductivity:
1600W/mK
— 4 times that of copper. Therefore, they are excellent at spreading heat and smoothing out hot spots.
My readers and myself have previously resorted to the Panasonic PGS graphite sheets from Digikey, which are to for a 180×115mm sheet. Now, I've managed to source these sheets by manufacturer AOQ, directly from China. They have the
exact same thermal conductivity
compared to the Panasonic counterpart of the same thickness, but these sheets are
4.4 times the size
. I'm selling these at
a quarter of
the price
of the Panasonic per unit area. Also because of the large size, you get a contiguous area instead of separate pieces, for even better heat spread.
Be sure to check out the heat pipes that I'm also selling at a discount! If you're using graphite sheets, you could probably also use some heat pipes. Order them together and save on shipping!
