Toaday during physics class i got the idea to strap on a acrylic tube filled with coolant directly covering a cpu heatsink. My dad who works with plastics says he could watertight it. do you think this has any possibility of working? i could also add a a small pump connected to a radiator at the other end.
PS: size is not an issue. my case is HUGE (3ft cube)
Or an acrylic tube connected directly to the IHS of the CPU so the fluid actually touches the aluminum of the IHS?
If the fluid is going to be directly contacting the IHS, it will see fairly poor results. Not very much surface area will lead to slow heat displacement and unless you had high turbidity in the tube, the water/liquid wouldn't draw away very much heat, while the heat it did draw away from the CPU would simply heat up the water until it had no more cooling capacity.
I see what you are saying. It seems plausible. I would say that if you have the means to do it, go for it. Try it on an old system first and see how it works.
Mods are always cool and unique mods are even cooler! Without totally picturing what you are picturing I can't venture a guess to the overall performance, but I love tinkering with things and it is a hobby/habit that has taught me very much about electronics, patience and trial and error.
Good luck if you decide to undertake the task. Post pics!
Sounds like an interesting experiment, go for it if you can stand to lose the CPU. And, if that is the case, some mild machining of the stock heatsink might help. If you had some grooves machined into the stock heat spreader on the CPU that were perpindicular to the water flow, then you might get some turbulation and more surface area to dissipate heat.
