As long as my temps don't increase, I can always add some kind of radiator in those 4 5.25 bays I have still open.

Watercooling won't make your room any cooler. The heat, however well it's being dissipated from your CPU and GPUs still needs to exit the case. And the radiator is just going to be putting off all the heat into one route as the hot water runs into the radiator and heats the fins up then the fans blow the heat off.

It really won't make a noticeable difference in temps, if any at all. The chips themselves are still making the same amount of heat but it's being cooled more effectively so the temperature sensor is reading nice low temps, but in reality the excess heat simply went into the radiator.

I could be thinking too far into this but I'm pretty sure thermodynamics still plays a part in watercooling a CPU.

Link to a thread on OCN.

If you want lower room temps may I suggest running a completely external radiator which hangs out a window or a window fan on exhaust?

Watercooling the PC will have little to no effect on room temperatures. tongue.gif

Hi -
If you are going to all the trouble to water cool your system you ought to add the cpu into the loop as well. What I would do first is measure the distance between the top of your mobo and the inside of the top of the case. I would buy the biggest, thickest, lowest restriction radiator that will fit up there (like a HwLabs SR-1 360, etc.) and match it to some low speed fans. Try to keep the number of elbows, etc, to a minimum and use 1/2 inch id tubing. I would go with colored tubing, distilled water and Feser1 anti-corrosion additive. I have been 100% watercooled for over 3 years and never had a block get gummed up. Also, make sure you add a drain line. I think the EK blocks are fine choices as are DangerDen blocks. To me an ideal loop would go pump > radiator>cpu> gpu>gpu>reservoir>t fitting> pump. At the t fitting have your drain line. I have my bay style reservoir in the optical bays. It looks great and makes filling/bleeding air easy. You can always add a 120 rad over the rear exhaust later.
Also keep the door fan - your mobo and ram still need good cooling. Especially after you overclock the cpu and gpus. Read up a lot before you start and be super careful when filling. And don't forget to use the psu jumper trick so you can fill with your system off. Have fun and Enjoy!

Good point, I didn't even think of that..hahaha

Well, either way, still wanting to do this project, on top of keeping my components a bit cooler.

Why not use the back of the case for a rad? i have 2 240mm rads one in front and on the back pretty easy to fit. Get EK holders and use the exhaust back fan

I considered it, especially since it would be really easy with my HAF X, but I decided that I prefer everything internal. There is just too much room leftover on the inside of this beast not to utilize.
