Would a 360mm rad handle this?

[Ali Man]

I know that I'm cutting it close. But I have a Phobya G-changer, 360mm rad (60mm thickness). It's quite the beast.

I was just wondering if this could be good enough to dissipate two GPU's i.e. (two GTX 1070's) and an i7 5775C.

I know that I'll be good if it was just one GPU + CPU, although with two GPU's, I think I'll need another rad, 240mm or 120mm.

What do you guys think?

I feel like it will be able to handle it at stock clocks, but the reason I water cool is that I overclock and want really low temps, and I'm not convinced this will be enough to do that happily.

If it were me I'd look into adding a little bit more radiator capacity.

Thanks man, that's pretty much all I wanted to hear.

What case are you using?

What case are you using?

It's a switch 810.

Plenty of room to add another rad. I was gonna get the switch 810, but went with the Phanteks Primo instead. The switch wasn't available in black at the time

That's a good case, good starting platform. I would stick a 420 in the top and whatever else you can fit in, but not go small like a 120 so 240 or 280.

Another great case, but much larger and closer to end game case.

Yeah, I made my Corsair 750D work, but it was by no means an ideal case for water cooling. Still I feel like I squeezed plenty of radiator capacity into it

I agree, this is a great answer.

Yes it will probably work to cool the components and to be honest you could probably overclock just fine but your temperatures will be high most likely. Most of us don't like that We tend to like low temps and low noise so we tend to generally go overkill on the radiator size.

Given your case I would personally look at adding another radiator to the loop. Depending upon your budget though you could go with what you have for now and decide if the performance is satisfactory.

Yea, it is a lot easier stuffing parts that need a bit of cooling into a case than it is to get a case to cool better.

I got the switch 810 in gunmetal when it was launched I believe two years back. I just restored it since it was in a million pieces as I hadn't used it for a while.

At the time of launch, it was probably one of the best cases to buy, was an upgrade from the phantom 410.

Just got an XT45 240mm from an [H] member here, would be using that along and should be good.

Now I'm thinking, GPU + GPU + CPU all in parallel or GPU + GPU in parallel + CPU in series.

The GTX 1070s aren't particularly hot cards, and the 5775c isn't going to dump all that much heat either. When I first started watercooling, I got a cheap Thermaltake 240 radiator (aluminum!) with a Swiftech 120 cooling two GTX 275s and a Phenom II 965, and temps were more than acceptable overclocked.

If you have the CPU in parallel with the GPUs, the difference in waterblock restriction would mean unbalanced flow between the components. I'm not sure how large of an effect on temps that would make, you should try experimenting.

My philosophy is that if you already have the parts on hand, you might as well try it out and see how it performs, it might surprise you. Watercooling components can always be added in later.
