How much is too much for a D5 pump?

Basically i have this setup at the moment and if i "could" Go single loop it would look a lot better!



I am planning on getting SLI 680's so they will be added into the loop, so it will basically be going Res > pump > RX120 > Mobo Block > Gfx 1 > Gfx 2 > RX360 > CPU > RX120 > Res

Now people have said having 1 loop and having 1 D5 cool all that is pushing it and i will run into temp problems.

All the rads are push/pull RX 360 has 3 GT 1850's on pull and 3 12.5mm fans on push, the bottom RX120 has 2 GT 1850's and the front RX120 has 2 Vipers now. All on full RPM.

But i have my 2700k @ 5ghz 1.38v. But i will probably lower this to around 4.8 when i go SLI

So what do you think? Is 1 D5 pump cooling that lot asking a lot from it? I have seen a youtube vid of someone doing it. But i would hate to sale my 2 DDC's to gimp myself on temps!

Well this was what ive been reading.. But people believe that my mobo block is very restrictive and would just kill the flow. Though looking at some videos on youtube the D5's look very powerful.

I could always get 2 D5's and run them with the EK D5 Dual Top so it gives it more head pressure but i want someone to confirm it would work before spending another £200+ on parts and to find its no good.

Ive never had DDC's like ive got now they are just vibrating so much.. maybe they are faulty but im not sure! Would rather just get rid of them tbh.

I was looking at getting the Koolance PMP-450S and run it at 12v as reading around running it at 24v makes it loud

So do you think it would cope with two blocks, (HK LT v3, FC GTX580) a RX360, RX240, a SR1 560, two Koolance QDC's and a 150 Balancer res? I've been told to add another, for two in series if I want to add the 560 to that loop

Yes.

I've ran CPU, SLI, chipset, PWMIC and 30 odd 90degree elbows coupled with 15 feets worth of passive radiator tubes off a single D5. It works fine.

Adding a second pump might get you another 1-2C in better cooling.

Another option (i think) would be to have a smaller pump in the middle of the loop as a relay.

Not sure if that's a good idea though?

that could do more harm than good tbh

an 18w ddc can cope with that with loads of headroom left so i wouldnt worry a d5 should cope even better

So why on Earth have I been advised to add another? My goal was improved temps via the rad, regardless of how minimal they'd be

Because there's a lot of people out there that don't know what they're speaking about when it comes to watercooling.

Ultimately, a second pump will get you better temps, but is that degree or two worth the £100?
 
It wasn't the pump that I thought would give me a reduction in temps. If anything I thought the extra heat dump would increase the temps
 
I was told the same Stock that a D5 will struggle bla bla bla but ive ordered my stuff and if it doesn't work im gonna throw it out the window :D

lol but the video's ive seen of the flow a D5 gives is 10x better than my 600lp/h DDC so.. i dont see it being a problem under 1 pump. But i will find out i guess
 
Hi
i have a d5 mine goes res pump 240 rad gpu gpu cpu 240 res and only have it on number 3 and it realy spurts back into the cyl res no problem.
Hope that helps a bit

I was under the impression that if running two pumps then they both had to be the same?

OK, if you wouldn't mind updating this thread to let me know how it goes :cool:

OK mate, thanks for the info :)
 
Well the Res dont come in stock until 26th so i guess ill be doing it the 3rd. so if you can wait until then ;) i will post back!
