this is a long post, if you dont wanna read all, then please just read my questions down below and try to answer them. OK. as im getting a new big case to mod soon, i figured id take a leap into watercooling (as im sick and tired of the crazy noise my computer makes). so.. since i want to cool almost anything in my computer, i need to know what would be the most efficient way of doing so. so.. here are the things i want water cooled: - CPU (p4 1,6) - Northbridge - GPU on a gf3 - Ram on gf3 - HDDs (two seagates probably) (- PSU.. that one might be hard and kinda dangerous. i dont think ill do that just yet) - i also plan on making a tiny little thing for my southbridge. nothing fancy, just a tiny block and a tube that goes right through it. (i managed to get higher fsb's with a tiny hs and some frag tape this way as my harddrive stopped giving me errors!.) and maybe system ram. what i dont know is if cooling the system ram will even me worthwile. will it perform better or run faster than my thermaltake blue ramsinks? i read somewhere that system ram runs better when its hotter. (ofcourse not tooo hot). i plan on adding the water tank, pump and radiator into a self made case along with 2-4 120mm fans. (this box will be in another room so noise isnt _that_ important. So... to my "real questions": - 1. what is the best route for the water to flow through? what water blocks should the water go through first and so on.) - 2. do i need two radiators or pumps? (like... first it goes through one rad and pump, then cpu, gpu and gf3 ram, then another rad or pump, then the rest?) will it work good enough with only one rad and pump? - 3. what pump should i get for this system? how much waterflow, etc. (there is about 5 metres distance between my computer and that "box full of goodies". (with the pump, rad and tank) - 4. what diamter tubing should i use? - how big must the radiator be? and do i need two for all these things? - 5. How big of a water tank do i need, if i want the system not to burn down before like 10 minutes without the pump? (so i can install some thermal probe thingy and shut down the computer automatically) - 6. what kind of radiator should i get? (im not gonna pay lots for it so some kind of used one from an old car or something that i can get somewhere would be cool) - 7. probably a silly question, but would water cooling my cdrw be smart. (mostly because there will be no airflow through the case at all, exept passive blowholes) - 8. after some testing i have also found out that my chieftech psu 330w which would be my "system" PSU would make an annoying buzz. and as i want a completely stealth comp, i need to find another way. so.. would it be possible to add that psu to the box with the pump and stuff too? can i extend the power cords 5 metres? if not i might just have to get some sexy enermax 441watts power supply yo replace it (do they make buzzing sounds too?) any other ideas you might have, just throw them in. i might even make a tutorial on how i did all this along the way. phew, long post. i hope youve got the time to help me.
