Can you dip a plastic frame in an ATX power supply safely?
Can you dip a plastic frame in an ATX power supply safely?
Well, I would consider using a fan or more than one fan in my setup. What if I only coated the bottom of the board? I only need to prevent it from possibly touching another circuit. I was wondering if conformal coatings would help dissipate heat or if that's incorrect. If I used something from MG chemicals instead of plastic dip, would that work? All I have to do is ensure some circuits don't touch each other closely. I thought coatings would be better than tape. Plasti dip was just a cheap option. I would most likely choose the conformal coatings.

Yeah, it would be cool but they might be a lot for you. Just remember I was younger in my teens, and I'll check if I have some of my old stuff.
You're absolutely mistaken. All conformal coatings act as heat insulators. A component can remain hot and still feel cool behind the coating, provided it's applied correctly. The old suggestion to use Kapton tape is the right approach. It won't come off if applied properly, and it's wise to heed advice from those with extensive experience.
The rubber will have zero effect on the magnetic field. Transfomer cores are made from iron laminations for 50/60Hz, or ferrite for high freqencies. Rubber is "transparent" to magnetic fields.
I've used small 600 Ohm 1:1 audio isolating transformers where the bobbin was protected by a thin layer of pink Silicone Rubber, probably designed to prevent water ingress into the windings, in humid atmospheres.
I wouldn't apply large amounts of rubber to a mains transformer or a standard computer PSU. Too much risk of overheating, followed by smoke and fire.

Silicone encapsulants are used in certain circumstances, but generally in circuits which do not generate significant amounts of heat.
