Will My RS360 Be Sufficient?

post #1 of 8
Thread Starter 
I am getting ready to put my 3 gtx 285's under water but not sure if my rad is up to it. Currently I just have my cpu in the loop but I finally found some waterblocks for my 285's. What do you guys think?

I'm not sure if I read correctly, but you want to connect three very hot gpu's and cpu to a single rs360? :O

I would at least add another 240Rad.

Moar. Rads. You might get. Ok temps, but that would be bad. Usually you want at least 120mm for one component, but the 2XX are hot, and you won't even have 120mm per part.

Hey dude!
Although the gtx285's aren't as powerful as the current GPUs they still have a considerably large heat output, which is not surprising for the gtx285, 280 and basically all the gtx260+

Generally, you would place one 120mm radiator for one graphics card but in this case you're using an rs series radiator, which is half the thickness of a proper rx series radiator (from XSPC) which has a lower fin count but still has a larger surface area to dissipate heat.

So my answer would be no to the XSPC rs360, but yes to an XSPC rx360 which is quite a bit more expensive.

Ok, thanks for the input, this is kind of what I was expecting to hear. I do plan on upgrading the rad to a Black Ice 360 SR1, do you think that would be enough or should I do another 240?

Really, that's not all that accurate. Take a look at Martin's comparison graph, and/or the individual reviews: RX360, RS360. At medium to high fan speeds, the RX only performs 7-8% better than the RS, and even at 500rpm the RX is only 15% better. An RS with push/pull will generally beat out an RX with the same fans in push only, there's not a HUGE gap in performance.

With that said, pretty much any 360mm radiator isn't going to be enough for 3x 285's and a cpu, unless you're running really over the top fans. If you're trying to keep noise levels reasonable, the suggestion of adding a 240mm rad to the loop is pretty sound, and a second 360mm instead wouldn't be too much overkill.
