Here is what we did with my ISA 428 preamp heat issue after installing an AD card. We added a heatsink (from an old 21" CRT, remember those...!!) with fan and some good heat transfer compound, a second smaller fan on the side wall (inside), a small rectifier/regulator circuit (***isolated from chassis ground) to power the fans and lastly, standoffs under the top cover to lift it up about a 1/2" and let more air in/out. Worked out great and all done from leftover recycled stuff laying around the shop.
Many thanks to Glenn L for the tech wizardry and Clovis L for the milling magic.

This is great. We have one of these at my studio. It actually did fry a molex connector which we replaced. It's working fine now but I'm interested in a long term solution like yours. I assume the ADC card is the source of the extreme heat. Since it came as an option do you know if it's possible to simply disconnect it and run the as is?
Hi Jared, yes, you could internally disconnect the big ribbon cable that supplies the ADC card.
