My Bolt with cover on and sitting on laptop cooler runs about 56 C. I took the cover off, took it down to 48 C. BUT, I harvested some drives from Directv DVRS. They had dense thermal conducting pads on the drives. I took one and put it on top of the heat sink. Took it down from 48 to 41 C in 10-15 mins!!! That's a BIG drop!! I also put one on top of the drive, Bolt will not report drive temp but if it does that well on the CPU it probably helps the drive also. Here is a pic of the pads, I used the grey ones for the Bolt. Has anyone got a Bolt ODT down to 41 or less?
