One or Two D5 pumps

post #1 of 4
Thread Starter 
I plan on watercooling my two GTX 980's and then my 4790k, cooled with two 480 radiators (probably the Black Ice Stealth or EK ultimate), inside the corsaire 900d case. The loop will be: Res -> ***Pump*** -> Vid Cards in SLI, parallel -> Proc -> Top Rad -> Bottom Rad -> Repeat

My biggest concern is the simple volume of coolant to be moved in such a big case and the two 480 rads. Would one D5 pump be able to handle all that? Any ideas on maybe putting all the blocks in a parallel loop, i.e. the 980's in their own SLI parallel loop while also being in parallel loop with the proc, and having the two lines meet at the top rad? This setup will already cost a pretty penny, so anywhere I can save, I need to try.

Single D5 could handle that no problem, save the money. This thread can give you a small idea of what you are looking at, you can search some more and you'll be able to find more. thumb.gif

The only consideration in pump choice is whether it (they) will deliver the flow rate to your rads and blocks that they need to be able to remove the amount of heat you need removed. Performance wise, the number of pumps doesn't matter, only the flow rate does.

An issue with parallel setups is that water (flow rate) will follow the path of least resistance, so each leg likely will have a different flow rate. That may be OK, but then it may not.

Just one D5 for this, no problem.
