My System Specs

Default Need some help with placement

Hey HWC, I'm kinda planning/hoping to W/C my GPU, but I would like to add another radiator in the loop. Here's a couple links to what it looks like now:

In case you're wondering, I'm using 5/8" ID tubing to and from the pump and 1/2" tubing for everything else, which is why I'm using those copper fittings. Excuse the dust, but I'm thinking about turning the res and pump 90 degrees about the y axis and mount them on the mobo tray. I don't know if that makes sense, but I'd also like to place a single radiator on the bottom, pulling air out of the case. In summary:

Reservoir > Pump > Single Radiator > GPU > Triple Radiator > CPU > Reservoir

So perhaps I position the single radiator with barbs closest to the HDD cage, then the outlet of that radiator to the GPU?

Again, this is purely hypothetical. I'm waiting on Fermi and a nice water block

You definitely do not need another radiator. A triple is more than enough for what you have.

Pump>CPU>GPU>Rad>Res>Pump

is my recommendation. Grab a pump top for the 655

Or if you don't want any mods to the pump

Pump>GPU>CPU>Rad>Res>Pump

This way you can simply add a GPU block without modifying the pump

I've read that the water leaving a water block is not significantly hotter, so it should be fine, but I don't know... I should take your guys' word for it since you have much more experience. As for placement for my pump and res, any suggestions? The tube coming from the pump to the rad blocks be from adding a big second card. I was able to crossfire two 3870's but I wasn't able to get two gtx 275's in there.

You could always mount the pump at the bottom, and the res on the back

Yup yup like Jackquel shows ^^.. I have mine setup with a similar setup, let me see if I can some pics here, camera's at home.. Only problem in putting the res there, is that the are does become tight in space, especially taking out the video card becomes sort of a challenge with tubes in the way.

Although if you want you could leave the placement as it is, and simply take out the tube going from cpu to res, and move it to cpu to gpu in, and then another tube from gpu out to res.

I had originally planned to populate the bottom grill with another 120mm fan, then thought about adding a single rad there, but since you guys suggest against it, I plan to place a 120mm fan there haha. Therefore I can't exactly mount the pump right on the bottom without obstructing the fan. Also, if I put the reservoir where Jackquelegs suggested, will that block the side panel 250mm fan? Maybe I could move the res up to the ram area... sigh... There's nothing worse than getting limited to changes because a tube is in the way or there is just the smallest obstruction ever in the way.
