After searching a bunch of different forums over the past few weeks I finally decided to post here because there seems to be a lot of good info bouncing around. I am building my first CPU water cooling loop and have a few quick questions on components/configuration.
(1) I'd like to mount the radiator internally if at all possible. My Lian Li case (which I don't thinks is optimum for water cooling, but I'd rather not replace) will constrain me to using a 2X120 rad after moding the top panel. According to what I've read, An i7 930 can put out approx. 250 watts of heat energy. There seems to be a consensus that a 3x120 rad is needed to deal with this temp load. furthermore as my rad will be internal (therefore surrounded by a higher ambient temp) I will possibly be looking at diminished heat dissipation. However I found this chart (I believe originally created/posted by Skinnee Labs and copied to Sidewinder computers) which seems to show this particular rad (Swiftech MCR220-QP Quiet Power 2X120mm) dealing with over 350 watts effectively at 2.0 gpm (fan dependent). The pump I'm looking at maxes out at well over 2.0 gpm (theoretically over 5.0 gpm though I realize restrictions in the water block and rad will make achieving this rate impossible). Can this radiator handle the i7?
Here's the link that has the heat dissipation chart on it: http://www.sidewindercomputers.com/swmcqupo2x.html
(2) If I do move ahead with the system I have planned here is my parts list (I have done quite a bit of price comparison and surprisingly all the parts I wanted were least expensive through this one company )

As you can see the system is pretty basic. The reservoir is one thing I'm not completely sold on as it only has an 80ml capacity. I chose it because my case has 2 unused 3.5 in bays and I'd like to utilize them if possible mostly to keep the inside of the case uncluttered. From what I can tell the res. mostly exists to allow the system to be filled/bled more easily and to reduce the amount of back pressure on the pump's intake. If these are the only functions of the res. then I can't see any need for a larger volume. Maybe a larger res. might make "bumping the pump" a little easier?
(3) It seems that the preferred order of water cooling systems is reservoir>pump>radiator>waterblock>reservoir. I'm having a hard time understanding why this is better than reservoir>pump>waterblock>radiator>reservoir. This is potentially a stupid question, but to me the latter configuration seems to have the advantage of running cool water through the pump. The only drawback I can think of is that the pump could potentially heat the water slightly before sending it to the water block which is not ideal.
This post turned epic . Any suggestions? Thanks
