AudioSan, I know. However, I'm pretty shure the colleague wasn't referring to the dissipation of the cooling aggregate which certainly is not 1000W.

Regards
Sven

thx for the intrest about the cooling. In practical terms we would use it to load power supplies during prototype testing. The 1000w would represent the needed load/ohm on a normal dc level . I have seen newer model of this cooling solution loaded with 400w without any issues. My particular one was used with loads of >300watts. i can also add that my colleague has some experience with amlifiers.

I've used this type of Chimney Heat Sink that was shorter than the one pictured with a slow/quite fan and dissapated a constant 500W without problems. I suppose 1000W would need a bit longer extrusion and a full speed fan

Hi Pwrs.
Thanks for the cooling system info. This is the format I want to employ but was going to combine conventional sinks to form a tunnel as had been shown in a post about an F5T buildup. Are these types of sinks commercially available? If so, would you please provide a link or contact info?
Thanks!

Thumbs up My F5 FirstWatt amp effort!!

Here she is, sem-completely. This has been a long and frustrating journey for me at times, solely, because of my own impatience sometimes...

But, I have finally gotten to the 99.5% completion stage..
