Copper vs. Aluminium heat sinks.

0	I know copper has better thermal conductivity but how much better is it than aluminium at cooling? copper cooling heat aluminium sink asked Aug 29 '10 at 17:49 sulljason 2.4k●110●126●156 edited Aug 29 '10 at 17:56

2 Answers:

Copper has a thermal conductivity of 400 W/mk, where as Aluminum is only 237 W/mK.

Copper will heat up and cool down almost twice as fast as Aluminum for this reason, which makes it a more optimal material for heatsinks.

Thank you. So copper is twice as efficient as aluminium.

Copper because it transfers heat better than aluminum. You going to get better cooling with copper.

I know but how much better is copper then aluminium?

it is 100times better, then aluminum!

number one it is used in pcb's which is printed circuit board, which you can make your own with copper!

I was looking for actual figures not exagerations but thank you for taking the time to comment. ^_^
