Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Working on warp speed's simplified hot water circuit I found a need for a cheap heat sink.

The one on the right cost $12 US on Amazon. I think I'm gonna need a robust heat sink please help if you can

So I will try it without the fan with
Will have 2 2" holes for natural ventilation on  (1 at the bottom the other towards the top cut in the back )
This is designed to fit in a 12x12x4" screw lid junction box
It weights in 1 1/2 lbs.68 kilograms
The vents will be 2" reptile vents (screen covered)
Will use curved parts of pizza pan to direct airflow
All I got for now
KindRegards
Steve

I would like to see the Mosfets centered on the heatsinks to make better use of conduction of heat but I like the junction box idea , I use them for outdoor combiner boxes

By going to a 12x8x4 junction box I-saved $20($35)
