newb idea..
 

was thinking... wouldnt it be best to have copper tubing on the return line and insulated tubing on the line going to the waterblock? that way the water would cool on its way back and stay cooler on the way too the block.. ehh.. im sure this has been thought of though.

people do use copper tubing, but it is a bit of a pain when making the system, a bit of heat would be removed though.

as for insulating the return pipe, i can't see why you'd do that, temps will always be over ambient

well, i guess the idea was to keep the water going to the block as cool as "possible" ... your right that it would still be over ambient though.. i guess thats why ppl use copper all over. ohwell, just tryin to think of ideas :)

would there be a way to use rubbing alchohol? anybody tried this? i know evaporation would be a problem.. but there would have to be a way to prevent it. .... maybe?

insulating the return pipe wouldnt be a bad idea at all I remeber when I used to mountain bike EVERY DAY and we used those camelback things with the water in them and the tube going to your mouth well the water in the tube coming to me would only get warm bc the tube wasnt insulated and the rest of the water in the sack was. So insulating the tube fix that problem. And where u have the tube in the computer system with all the heat coming from diffrent places it might help quiet a bit so someone go try it!

no =) think about it... if the water IN the tubes is always WARMER than the air... any type of insulation will KEEP THE HEAT IN THE TUBE... even the coolest part of the tube is still warmer.
so to benefit at all from copper tubing, you would want it all NON insulated.

digital chaos has got the idea I was trying to express...

erm... guys... the only line he was mentioning to be insulated was the one feeding the block... not the return line... the return line is the copper one to help dissipate heat into the air all of the way back. Good logic but in actuality the only problem is that the water in the copper return line is probably moving to fast for the pipe to be effective.. only problem with insulating the feed line is that it won't really do anything... the case isn't warm enought to heat the water in the feed pipe especially since the water in the feed line should be very close to ambient temps anyway... unless u were chilling the water... then u might want to insulate it...

so we'd have to use a water chiller...
