I need help with gpu only waterloop

[wotevajjjj]

Hey guys !

I've been saving up for my new build and I think I'm ready to do this.
I'm going for a prodigy chassis but with a new bottom and top, thats almost done tbh.

current specs:
prodigy orange
gigabyte Z77 itx
crucial ballistix orange
i5
orange phanteks
ax760i
256 gb samsung 840 ssd

But now for graphics..
I want the 7970 (it's only €340 for a reference one) and the swiftech komodo block. But i cant make up my mind on going with eighter a 200*25 rad or a 240/280*60 rad (if that fits in the front next to the gpu). Also i dont know what pump to use for a small loop like this and I wonder how much cooling performance is lost by not going with a reservoir. So, any tips are much appreciated.

Whats cooling the CPU?

cooling performance is lost by not going with a reservoir.

Simple answer None at all. The res will flatten out spikes and the bigger it is the longer it will take to reach max temp.

I would personally go for 120/140 based rads 200mm fans are more expensive, and will have less static pressure.

the phanteks air cooler will. I'll go for a 280 than, should clear the gpu from what i've seen.

Which Phanteks?

Bear in mine how close the CPU socket is to the PCIE lane. If you put on a big air cooler, you'll cover the PCIE lane and be unable to install a graphics card

I noticed that, ill probably go over to the stinger or the asus deluxe board, too bad the colors dont match on the asus board

ill go for the twin tower one

gpu blocks are expensive in comparison to the cpu ones, why not get rid of the air cooler and throw in the cpu block in there? 240/280 should manage them both.

also res isnt mandatory but help with many things, if you cant fit it in, you can always run it externally if its necessary

I simply don't like the way cpu blocks look to be honest. They're also not needed, there is ample room for a giant heatsink, but on a gpu there isn't. Also a 4.7ghz 3570k wont put out anything like the heat of the gpu. But the main reason is looks.

You'll seriously struggle to fit the Phanteks on with a graphics card on that board.

I built my mate a rig using a gigabyte Z77 ITX board in a prodigy a couple of weeks ago - There's very little space there.
I'll have a look at his at some point.

I know that's a slightly different cooler - but it'll be the same story I think.

Also, the Gigabyte ITX boards have no way of changing voltages to the CPU in the BIOS. So you'll struggle to get to 4.7ghz unless you use software within the OS. Even then, 4.7ghz on a board like that will be a struggle as it only has a 4pin CPU connector.

Might need a rethink

thanks for sharing that picture, but now i'm afraid that if I put it on the evga stinger it may hit the side of the case.. So asus p8z77 i-deluxe it is, now i have to machine new heatsinks

Ha anyone gotten an idea on what pump I should use ? it has to look good and preferably have the in and out port at a 180° angle
