Will this loop work?

shonik09 · 15 Jul 2016 at 18:29

So currently my loop is as follows:

1080 EK full waterblock (1080 FE)
Asus x99 monoblock (i7 6850k + Asus X99 Deluxe II)
EK 360 CE rad
EK D5 140 Revo PWM pump/res

My questions are:

1) Will I need an additional radiator to adequately cool when overclocking both the GPU and CPU relatively hard?
2) Will the single EK D5 Revo PWM pump be enough for this loop, even if I included an additional 240 rad and another GPU?

Any help is greatly appreciated!!

usual rule of thumb is 120 for each component and extra 120. so 360 should be fine. just make sure you have good cool air for the rads. the pump will be fine i have a d5 running 480 and apparently can do more as well.

1. No you dont, spend more on decent fans instead
2. Yes it will, i've got a D5 powering 720mm of radiator

If you can get more then get more radiator though, then you can run the fans low and its quiet which is the half the reason you do it.

Right OK, yeah so the rad I have is 60mm thick, and I have 6 fans for a push/pull config, so by the sounds of it I should be good

Guessing even if I have 2 x GPUs and CPU overclocked, the single 360 x 60 rad should still be enough with a push/pull config?

Another quick question - how do you guys measure the temp of your loop to be sure it isn't oversaturated heat-wise?

archerz · 15 Jul 2016 at 23:31

you can get a 4 way connection and add a temp monitor to one of the inputs

for example!

make sure you get the right fitting though, above is just for the idea.

Sorry if this is a stupid question, but where on the motherboard would you connect the sensor?

ChrisLandin · 16 Jul 2016 at 20:54

Some motherboards have temp sensor headers

Personally I have mine connected to my fan controller as it has a digital display

I would get 2x 360mm rads , i personally have 2x 480mm rads but i have the 900D case , im about to add another 120mm for the rear . mine goes like this , Res-pump-bottom 480 rad-2x980ti- 120 rad - 480 rad -CPU - Res .

But will a single D5 cope with 2x360s? Tbh I don't think they will fit in my case anyway as I have an evolv atx. I think the most I can do is a single 360 and a single 240...

archerz · 18 Jul 2016 at 16:29

i'm sure it will; on another part of this forum i asked the question about 2 x 480s and said it should be fine.

Ploppy2k3 · 18 Jul 2016 at 16:35

I use a single D5 to push 2x480, 1x240m CPU and 2 GPU

it works like a charm

the D5 pump is simply a monster.

shonik09 · 18 Jul 2016 at 18:12

Awesome, glad to hear the D5 pump was such a good choice

I think I will get another 240 rad. One thing I'm not sure of at the moment is which fan speed would be optimal. I initially bought 3000rpm vardars, but am finding them to be a little loud... Does anyone have any recommendations for fans that are powerful enough to support heavy overclocking for a build like this?

Thanks for all of the input guys!

tyler_jrb · 18 Jul 2016 at 18:52

3000rpm would be way too loud. I have sp120's on mine and run them at 60% which is about 12-1300rpm I think.

Vardar's are probably the best your going to get for rad fans other than noctua's to be honest.

I'd seriously reccommend getting a fan controller. That way you can either have them come up on CPU temp or GPU temp or water temp what ever. Same with the pump if you wish to do so. You can have them idle for desktop or even switch off if you so wish.

Mine was just a cheaper tuck away job. I added a heatsink to mine though to keep it cool and more efficent due to it running over 1A at load on a single pwm.

I'd also say, don't go push pull. I did that with all my rads when I first built it. Took them off due to noise. Horrid warble noise even at idle due to speed inbalance. Didn't notice much if any difference in temps to be honest.

And yes a single D5 is fine. I have mine running 2 480's, 1 240, 2 GPU blocks and cpu block all on setting 3.

shonik09 · 18 Jul 2016 at 19:12

Ah wow. Yeah I actually do have a couple of fan controllers, one of which is PWM along with all sockets on my board, so I have a pretty good system for fan control. My pump is actually PWM, but great to hear I will not need to worry at all about it pushing the loop. I'll take a look at some other fans, as yeah the 3000's are defo loud...

archerz · 18 Jul 2016 at 21:32

don;t forget to take some pics when you've build it

shonik09 · 19 Jul 2016 at 14:04

Haha yeah will do. Do you guys have recommendations for good fan speeds to keep an OC'd loop cool with 2xGPUs and a CPU (basically the loop I've been describing)? Was thinking either 1450 or 1850... Guessing any higher would be overkill? Thing is I have the EK 360 XE rad, which is 60mm thick, so I think I'll need some relatively good fans to cool it properly. I also wasn't planning at the moment to add a rad, so it'd be that single 360 for 2 GPUs and a CPU...
