So here's my idea. I was thinking I could get a tiny pump, reservoir, and radiator (not anything that they'd sell at petras or anything like that, and then find a block that I could work with inside my laptop. I have a free laptop hdd slot which I could put the pump and res in. Obviously this wouldn't be using the same tubing as a regular wc loop, I would have to use some tubing that would be about the size of a drinking straw, which I have at home here. I really just want to cool my laptop gpu. What do you guys think? I've seen some threads on this, but i'd like to fit it inside the case of the laptop.
