Home made PC water cooling

[darryl_co]

Hi guys,
I am planning to water cool my pc and create all parts custom built.I need some expert guidance.
I was of the opinion that longer serial water track in cpu block was better but after reading a post at http://webx.dk/oz2cpu/pcmod/water.htm I am not sure if long serial water track or short parallel water track.The total amount of water in the cpu block would be the same in both cases.As seen people out there create their own water cool system which are very expensive according to me
1) I plan to use 3 mm copper plates as the contact material with the cpu and gpu, water tracks cut in plexiglass fixed on top.Sealed with gasket and then with silicone.3mm copper will be faster to cool and give enough strength to hold against the cpu.
2) A submersible pump(In India we get AC 230 vols operated pumps) A reservoir mounted at a higher level, above the DVD drives.Idea is that water would seek its own level so easy for the pump as it oly has to circulate water.
3) Use P3 cpu cooling fan and its circuit enclosed in plexi glass as water flow indicator.
Please guide

Short tracks provide the most consistent cooling. Long tracks provide the best heat transfer.
For a processor, best results will come from consistent cooling. It is better to have an inefficient heat exchange than a hot CPU core.

I have made few custom loops, but only for My videocard. I used 230V submersible pump in plexiglass reservoir plus internal radiator of a car (the small one). I liked this submersible pump so much that I think I will never ever buy 12V pump Good luck with your project!

In India our pc are not on the whole day but they are switched on and off(mains power off) many times in the day.Advantage of using mains operated pump is that the pump would start circulating the water as soon the mains power is switched on even before the soft power button on the pc is pressed and remains on when the pc is shutdown until the mains power is shutdown.
Bundy please short or long track is advisable? Isnt long track heat transfer mean that cpu core heat transferred to the copper plate would be transferred to the water flowing through it and out.

My point is that a short track is best for a CPU but will not be as efficient as a long track.

A long track will mean that your cooling system will be more efficient but that might cause uneven cooling. When you are at the limit of your cooling system (i.e. when OC), it will be the hottest part of your system that fails.

The best for you would be a short track IMO. If you need better cooling, pump more water through the system or fit more fams on the radiator rather than making a longer track block.
