RE: Heatsinks

Eight? Wow that's a lot. I am using one with two IGBT's up to 2KW (or
more) and it doesn't easily get warm, even on repeated long runs >2-3
minutes. I use a nice "quiet" AC muffin fan that will work great for up
to two P-IV heat sinks. You do have to drill mounting holes through the
sinks.

Fortunately I can get them cheap...

David Trimmell

Yeah, I used 8 of those and it did work, but even the cheaper ones, 8 of
um
cost a fair bit, very noisey with 8 fans, trying to find a larger
heatsink
really....
