Thermal characteristics are about the same as of copper. Look up graphite, and you got it. The big deal is that it has higher thermal transfer capacity in the direction of the fibers, so you can make two components track quite well thermally. I can't remember the temp differences of the case to carbon heat spreader, but I'll measure that this evening. Why such interest all of a sudden? :( Magura :blush:

Choky is up to something. Something is brewing. First he was asking that question about chokes, now this... I guess it is an amp with chokes and with some devices that needs fast cooling. ;)

Another high quality image :( Anyhow, it shows that the donut project actually did end up as a pair of amps.Magura ;)

:blush: Is that water cooling for the amps in the back, or the cooling on the amps is so good that you have to warm up the amps in order to work well? :) Looks magnificent!

Naah, just not that many options, when it comes to placing the system. Not that it makes any difference actually, but I too thought it would, so I measured the temp of the amp, once in place, and then moved away from the radiator....about 1C difference :( And now for something completely different: I have made a CLEAR photo. Mucho effort, but worked.Magura :blush:

Metal man, are you coming to BAF this year? We might have a class exchange. You do milling class and I will teach you all that you need to know about photography.
