Need help on watercooling an i7 and a 480gtx

post #1 of 15
Thread Starter 
Hey guys, I've read lots of similar threads but I need some custom advice here, please.

I want to do a loop inside a CM-690 for an i7(920) and a 480gtx. Is that possible, and if so, is it a good idea?

Apparently I can fit only a 240 rad on the top and maybe another 120 on the regular rear exhaust. Will that be enough for cooling both components? Is the 240 alone enough? (would be great if it were)

Anyways, I want to do it internally. No rads outside, especially at the back cause I don't have much clearance between the case and the wall.
Behind the case it would only work if I could put the rad perpendicular to the back, in a way that the fans would be positioned parallel to the case's side. This case does have holes for tubing. in the back, so maybe that would work.

It will be my first try with watercooling and I may be thinking in the wrong direction here so, any other ideas are more than welcome.

Thanks a lot!

If you keep everything internal, a 240 and a 120 would be bear minimum IMO, but your best bet would be to do an internal 240 and an external 240 with a radbox on the back.

Really? I was kind of hoping for a single 240...
Well, guess I am too optimistic.
How much can a single 240, like the black ice for example,
handle? Like 400w?
Thermi alone produces some 400w, right? So I would need more 200 or so to be safe with an overclocked i7 or am I trippin here?

not too sure about wattages but as you probably know, the 480 is one of the hottest cards ever so if your planing on doing any OCing I just don't foresee a single 240 working but I would love for someone to prove me wrong. Of course if you can afford to keep the ambient temps in the mid-low 60F range and do a push pull I don't think you would have problems. There is also the ice dunking method...

Yeah, maybe a 240 could handle the 480gtx but not more than that, right?

hello,

I had a 920 running inside a cm-690 with a slim 240 rad and it worked fine, the temps were reasonable.







My main concern was having it all internal and a flush finish to the case keeping its original shape. I had to use slim 120mm fans for this and the black ice stealth 240 rad. Temps were ok but i never really intended for it to be a massive OC beast.

Using my old setup i would not recommend putting a 480 onto the loop.

I upgraded to an obsidian 800d and kept the same loop. Temps didnt change at all with the change of case.

I then got a 480 and decided to replace the thinner stealth rad with a 360 standard width one. When i added the 480 to the loop and changed the rad, temps did not increase, in fact, they went down a little. This can be put down to the larger rad and full sized 120mm fans im sure. But the 480 didnt boil the loop like i expected it to.



So i guess my is 480 on the same loop as an i7 is no problem, but i would recommend a 360 rad, which isnt going to happen inside a cm-690 without some serious case modding.

Wow, nice rig, man!
So, a 240 plus a 120 would be roughly equal to a 360, no?

I'd say go for a CPU loop. The CPU will need the most cooling considering the stock cooling on the 480 is enough to cool it adequately.

In theory i suppose but im sure i tried that with my cm-690 and measured up the rear exhaust fan deciding there wasnt enough room for it inside the case.

One thick 360 rad with 80-90CFM of air going through it will keep a 4.0Ghz 920 and a Stock 480 at decent temps.

only in benching would temps go a bit high and even then you only bench either the CPU or GPU, rarely both.

I find that only in metro after about 3 hours gaming does my slim 360 with 60CFM fans start to heat up the liquid by 3C per 30 mins.
Im sure with a nice 2X 240 or even 1X240 + 1X120 you will be able to curb your CPU + GPU heat.

Note: I use a Cpu and Gpu block only, I dont cooler the vrms on the card or any of my motherboard with water.
