It's still a lot of power to be cooled with 2 heatsinks (including CPU heat, it has a total heat output of 300W, if the ambient temp is 20° that means that deltaT is 26° and the heatsinks have a C/W ratio of 0,087; that is 2 times better as a watercooling kit ...).
If my calculations are correct of course :D
Quick reverse calculation:
Let's assume the two heatsinks have a C/W ratio of 0,2 . In his initial testings, the hot plate is at 33,8°, so with 20° ambient temp, deltaT is 14°. 14/0,2 = 70W, so 35W per TEC. |
