Extending CPU only loop to include a watercooled GPU

post #1 of 8
Thread Starter 
Hey,

I've picked up a GTX 680 and I'm planning on putting it under water. Here is what my loop currently looks like (ignore the graphics card, this picture was taken before I got the 680):

400

However, the issue I'm currently facing is the 1/2" ID 3/4" OD tubing is not very flexible without kinking so I'm not really sure the best loop design. Is it worth scrapping the 1/2" ID, 3/4" OD tubing and going for something smaller and more flexible?

Also mounted in the top is a RX360. Was wondering if it was worth picking up another 120 or 240 rad as well?

Thanks smile.gif

personally i'd say there is no point changing the tubing as youll need new fittings as well - expensive!

also, the 360 rad should be plenty for one cpu and a gpu unless you are overclocking the nuts off them

I would have thought that RX360 would handle it, especially considering how power efficient Nvidia has become with this one.

2 options - better tubing. i got my clear primochill 1/2 3/4 a couple of days ago and it bends just as well as my 7/16 tubing. option 2 is just to buy a couple angle fittings and call it a day. either option is tons cheaper then replacing sized tubing.

My Rx360 cools a 2600k (4.815Ghz) and a 7970 (1250mhz) Just fine, When gaming the 7970 doens't break 40c and the 2600k doesn't break 50c.

Why not move the pump?

If you can put it towards the front of the case (right side in the pic) with the res portion closer to the open side it would give you some extra space to route the tubing to the GPU.

Switch the in and out tubing on the rad so that the tube going down to the res is straighter.

Possibly consider some 45° fittings to go from the pump to the GPU.

I'm not sure if that will work, but it is an idea. Have a play around and see what you get.



Edit: Stuff that, better ideas

1. Flip the pump so it is at the front, with the res pointing to the left.
Run straight into the rad, then to the CPU > GPU > res. You will need to turn you CPU block upside down to maintain the correct in / out ports. That is fine.
Option 1 (Click to show)
400

2. Flip the rad 180 so the ports are towards the back. Go pump > rad > CPU > GPU > res
Option 2 (Click to show)
400

Again, I have no idea if either of these will work well. You may need some angled fittings, but play around. Be creative.

Thanks, I'll pick up some better tubing. The current tubing I'm using is not really that expensive so I'm not really losing anything.

Thanks for the suggestions. I'll have a play around with those two ideas and I'll also pick up some assorted angled fitting when ordering the GPU block to give a bit more flexibility.

Also thanks for those who confirmed that the 360 rad will be just fine.
