I was just wondering if anyone has tinkered with using a PC liquid cooling system for thier amps or AVR. I'm toying with the idea to reduce fan noises.

Anyone had any experience with this yet?

None of my amps have fans. I don't know of any non-pro amps that have loud fan noises.

I think if one needs to consider that level of complexity to get rid of fan noise, you're better off to get different amps.

or install them in your utility room like i did, i do not have any fan noise issue when the door is closed :D
