Adding GPU to loop- quick question...

[DoneADougalOnSofa]

Hi folks,
Currently watercooling my CPU with an XSPC Raystorm 360 kit.
I've bought a block for my GPU, and picked up another res and two 240mm rads, with the intention of chucking it all on the same loop.

Is this a good idea? Or would I be better off picking up another pump and running two separate loops?
Just worried the pump won't be up to all that extra pipework...

Cheers

What pump came with the kit?

A D5 or DDC can handle 2 blocks and 3 rads with ease. I personally would stick to one loop as it's fewer overall components, fewer points of failure and cost. You're also then sharing your thermal headroom - any unused radiator capacity will naturally cool the system down if, say, your GPU or CPU have less than full load.

I don't think there's a lot of value in keeping cooling separate when ultimately, either an overheating GPU or CPU (in case of pump failure) will stop your system working.

It's an 'X4' pump- rated at 600lph and 3m head.

I'm sure it'll do the job on a single loop. Was just after a little confirmation!

Edit- it could be a D5. Either way, you've answered my question

You don't even need an extra rad tbh most people really over spec this for no good reason.

A good triple rad will cool an oc'd CPU and any 250W TDP GPU with ease.

Separate loops will be more points of failure and more maintenance for no gain

You should be ok with just adding a single 240mm rad to your existing 360mm rad and have just a single loop. Dual loops can look very messy with the extra tubing. If your pump is a D5 then it is more than powerful enough for that lot. I have a D5 vario pushing coolant through two blocks, two rads, a big inline filter and around 10m of tubing and copper pipe with no problems at all.

I would not try cooling a Vega 64 and a 2700x with a single 360mm rad no matter how good it is.
