Water Cooled PC Power & Cooling 1KW supply
I had a custom machined water cooled heat sink made for the PC Power & Cooling 1KW supply. I also went with a 120MM external fan, which runs much quieter. But as a result of the water cooled heatsink, the fan is running almost silently all the time.
I have construction pics for the heatsink, and would be happy to post them if anyone is interested.
