Quick question about SLI watercooling.

post #1 of 14
Thread Starter 
Well, you guys were right. The WC bug hit me, and hit me HARD. It was only last month that I began by watercooling my i5 2500k. Well, a couple of days ago, I decided to put my 560ti under water. That block is currently in the mail. Now, I have decided that I want to go SLI, so I went ahead and bought a good PSU to do SLI with. Now to my problem:

I want to order another 560ti, but it might be several weeks or months before I can get the secons card under water. Not so much because of the cost of watercooling, but because of the cost of the case which I am planning on putting it all in - a Caselabs M8. Right now my mid-tower case is holding a RX360 rad, which I am sure is fine for the CPU and GPU, but I do not think it will be enough when I add the second GPU.

Therefore, my question is whether I can run one GPU under water and the other under air for a couple of months? If not, my options are to put them both under water on that single rad or leave them both on air until I move to another case. What do you guys think?

Yeh you can WC one and leave the other, I would WC the top one until you can afford the block for the second one, since the top one is generally the hotter card due to limmited air flow.

Pretty sure you can cool both GPU's on that rad, as long as you don't go balls out on the OC's.

Heck, I'm running tri-SLI in an ATX case... it'll fit... =P

If you can fit an RX360 rad into your current case, this is plenty for 2 560s and a 2500K. I had two 6950s and a OCed 2600K in mine without issues. If the cost of the block isnt the problem, order it, and go with that. While the caselabs cases are wonderful cases, they are absolutely not a necessity to make your solution work.

Thanks guys, + rep for all of you. I think I will go ahead and WC the whole thing since you all think the rad will take it. Since I am going SLI, I will clock the cards at stock settings - no need to overclock with that setup (at least until I get my next case and put another RX360 in it).

One more quick question: will the Rasa pump that comes with the kit have enough flow pressure to go through one RX360 rad, the Rasa CPY block, and two Heatkiller 560ti full cover waterblocks? If not, that is another reason to just watercool one for the moment.

Thanks again.

I think you may come across an issue there, but I have read other members who said it works. It may not be idea, but for the time being, it will function. If you want to replace that, get a MCP655 variable pump and an XSPC dual 5.25" bay res with d5 pump mount. This would take the place fo your rasa pump and be the same size.

655 for sure. You should be cool with the 360 though. I have a 920/470/470 on one trip rad. The SB really isn't a heat issue.
post #9 of 14
A 360 will be enough.

LOL!!!! Well, here is what is currently on the way:

Sidewinder: 2xHeatkiller GTX 560ti full cover blocks
Newegg: Corsair 850AX modular PSU
Amazon: EVGA 560ti SC (same exact card as my other card so hopefully they play nice in SLI)

All of the barbs and accessories that I will need will be picked up locally from Performance PC's. I am in no real big hurry, so I will determine what I need when the parts get here.

We will see how this plays out with the RX360 stock kit. However, I will update the pump and res soon. just need some time for my wallet to recover.

P.S. FTW should expect a order from me soon as well to pick up a kit to sleeve this new PSU!!!
