how long does watercooling last

[subbytna]

before you have to refil your system...or how do you know what's going on in the tubes?

Just not 100% sure how it works. Is there a time limit when you have to replace all the parts?

How does the water pump around?

Does the radiator have to be a certain size for cooling?

Do the fans suck the hot air out of the case or does the air coming off the rad get blown out?

if you keep your loop closed and don't go adding liquid etc then you can have it in that state for at least a year or so (this is pending you use anti corrosives and biocides).

generally i like to give mine a clean every 6-8 months as i use dye in one of my loops, so start to lose performance around that time after the loop has originally been filled.

as for the pipes, chemical erosion will take an age to damage your pipes to leaking/disintegrating...

the water pumps around by using a pump.... duh

the bigger the rad the better cooling performance you will get, up until a certain point where gains are minimal.

have the fans anyway you want; but i find having the hot air getting shifted out of the case to be more logical
