Watercooling a PC with a central heating radiator? Answered
So I'm completely new to water cooling, I own a closed loop cooler and I know the names of the water cooling parts and assembly, but I have no real experience.
I presume it's possible to use a normal radiator as a passive radiator in a loop, but I've got a couple of questions. First, do I have to be worried about what the radiator and waterblocks are made of, are the metals important? Second, will I need a significantly more powerful pump than the standard D5?
P.S. the rad I had in mind is this http://www.screwfix.com/p/flomasta-type-11-single-panel-single-convector-radiator-white-300-x-800mm/38602 It's rated for 1505 BTU/hour, which equates to 441W, which is in theory plenty my PC (4670K, HD7850 which I'll probably upgrade in the near future)
The reason for using this kind of radiator is because they're far cheaper and passive, although I suppose the increase in pump power may negate quietness of no fans. It's also more fun ;)
