Hey everyone, just in the process of finishing up my loop.

My current pump specs are as follows: (XSPC x4 Photon)
  • Maximum Flow: 600 lph (12V)
  • Maximum Head Delivery: 3m (12V)
My loop will contain:
Heat Killer IV CPU Block (7600k)
Heat Killer IV GPU Block (1080TI)
3 x XSPC TX (Ultra Thin) 480mm Radiator
1 x XSPC TX (Ultra Thin) 360mm Radiator
XSPC Photon 270 Resevoir
XSPC x4 Pump
4 x Koolance Quick Disconnects QD3
11/16 Soft Tubing

I am assuming I will need a second pump for all this, but I am unsure which one. I see people always recommending the "D5", but I can only see a screw ring version on OCUK? What exactly am I meant to screw it in to?

Thanks!

You either need a pump top or a top/res combo for a d5 if you're buying it solo. Something like https://www.overclockers.co.uk/aqua-computer-ultitop-d5-pump-cover-for-d5-pumps-wc-32y-aq.html should do you fine.

I have to question your rad overkill though... Are you trying to cool a dual socket SLI setup or something insane? If it's just the 7600k and 1080ti then 1 of the 480's would probably be enough unless you're doing some heavy oc'ing.

Thank you!
Nope just the 7600k and 1080ti for now (will be upgraded shortly). I like to run fans super low and still achieve low temps. Ideally looking to change my fans out for this next build so they can run at 0rpm 99% of the time.

Edit: Also the 7600k is at 5.2GHz and 1080ti @ 2GHz

For your loop, you could probably run without fans with that many radiators. I would try your loop with x2 480s, or maybe a 480 and 360. I'm all for lots of radiators, but I know you'll hit diminishing returns with the rads you have. Arctic PWM PST great rad fans, quiet, great control, they have a 0 rpm mode, and they can be bought in 5 fan multipacks, downside, or upside is no rgb, but for the price and performance, I bought 16 and just used rgb fans for the case fans.

I have been running with 1 x 480 and 360 for the last few months. If I leave the side panel off I can run at low rpm and maintain water temps under 40 degrees. As soon as the side panel goes on, water temps increase a lot. I have changed orientation of some of the rads and will be running the P12's with an aqua computer controller based on water delta.
 
Thank you both for input. What are your thoughts on Standalone D5's with a separate reservoir vs D5 Pump Reservoir combos? Are their any downsides to going with a combo opposed to standalone?

That certainly is a big boy res you've picked! Will it actually fit in your case? 303mm + the d5 height is quite a lot for a shelf in the middle case. The pump will fit fine but you might be stuck with a monstrosity that you can't shoehorn in the chassis :p

I measured the space, I have 41cm of height available. Going to sit behind the first rad:

I also think OCUK's details on the product page are wrong. Look at the below dimensions direct from heatkiller: 279mm with the D5 and stand.
