D5 Pump Limitations

A D5 is more than enough for that loop. The only resistance it's really facing will be from the GPU and CPU block, and with only one of each, it's more than capable. Your best bet right now will be to boot your system normally with the PWM pump cable connected to some fan header on your mobo (could be fan, w_pump, cpu_fan, etc). Depending on your motherboard, you might still be able to view the RPM's in the bios itself without booting into an OS. Max rpm of an EK D5 should be around 4800rpm (at least my pump is). Crank the pump all the way up to 100%, make sure RPM's are somewhat around there, and monitor cpu/gpu temps. 

If your pump is significant low, you likely have a defective pump or defective power source, whether that is the molex cable or psu itself.

Hey all,

 

I'm currently in the process of bleeding a custom loop I just put together (my first). It's a full cover 1080 Ti block, 360mm x 29mm rad (Nemesis 360GTS), CPU block (EK Supremacy Evo), 240mm x 38mm rad (EK 240 CE), and a pump/res combo also from EK, in that order. The loop is soft line and has 4 90 degree fittings. The pump has both a molex and a PWM fan header, but it gets only power from molex and only the PWM signal from the header (I think), and it's currently only plugged into the molex, with the 24-pin jumpered.

 

The flow I'm getting is laughable. Imagine a piece of soft line with the smallest trickle of water flowing down it, and that would be the kind of rate I'm getting (I can see this exact thing from one of my tubes that has an air pocket I'm having trouble removing). I can only guess that this means I'm reaching the limitations of head pressure (or just general resistance) of a D5 pump. Would anyone else be able to confirm this? If this is the case, I'm assuming adding another pump inline would alleviate the problem. I have a spot in the loop where this would be relatively easy to do; Should I go ahead with it, or am I just missing something?

A D5 is more than enough for that loop. The only resistance it's really facing will be from the GPU and CPU block, and with only one of each, it's more than capable. Your best bet right now will be to boot your system normally with the PWM pump cable connected to some fan header on your mobo (could be fan, w_pump, cpu_fan, etc). Depending on your motherboard, you might still be able to view the RPM's in the bios itself without booting into an OS. Max rpm of an EK D5 should be around 4800rpm (at least my pump is). Crank the pump all the way up to 100%, make sure RPM's are somewhat around there, and monitor cpu/gpu temps. 

If your pump is significant low, you likely have a defective pump or defective power source, whether that is the molex cable or psu itself.

No dice. Tried a couple different headers. I can feel the pump ramp up, and the BIOS does show it running at 4750 RPM, give or take. No difference in the loop though.

 

Edit: It's possible there is a problem in the CPU block. The trickle of water I mentioned is on the outlet of the CPU, betwen it and the front 240 radiator. I when I changed out the jet plate, I may have installed the cold plate 90 degrees off, so it's blocking flow rather than directing it. I guess I'm gonna learn how to drain a loop now... And to think, I almost didn't add a drain port.

8 blocks and 3 rads on a single d5. The pump isn’t the problem. 

 

If you are jumping the psu and have the pump signal plugged into a header, that is an issue. 

 

Keep that unplugged. 

 

I tend to just boot my pc like normal. Get into windows and turn the pump speed to max. Or on some of my boards, I have optfan headers, which run my pump at max and bleed the loop quickly. 

 

So id start at the loop itself to ensure there isn’t a massive kink, then ensure pump speed is at max.

@Airdragonz @Mick Naughty Thank you both for the help. I did indeed have my CPU block assembled incorrectly. Got it all put back together and it seems to be working as expected. Thanks again.
