D5 vario pump

I used to be able to do mine with a finger nail.

Anything that you can turn it with really. So you know, it's a very smooth thing to turn - if you're having difficulty, make sure you aren't trying to turn it the wrong way.
 
Yeah I use a thin flat head screw driver. dont twist it too much though its easy to keep turning and break it. Just have the arrow pointing to the number you want it at
 
Oh wow. My vario starts at 2 then goes 1 0 5 4 I guess manufacturer failed at numbers?does that mean my two is 1 and my 3 is at 0?
 
That sounds a bit stupid :lol:. Mine goes 1, 2, 3, 4, 5 as you'd expect.

Despite the order that's labelled, I'd imagine the real settings are still in order, otherwise the manufacturers would have really had to go out of their way to screw it up lol.

Oh yeah, and I use a flat head screwdriver.
 
How much power does a d5 pump have? enough to pump from the front drive Bay Area to top quad rad? My d5 is pushing at a extremely slow rate
 
D5s are pretty much the strongest pumps people commonly use for watercooling. My loop consists of two radiators and three blocks, the pump is on the second lowest setting, and my temps are perfect. I've tested it on the lowest setting and it still flows fine (I have a flow indicator) but I can't hear it on setting 2 so I might as well keep it on the higher setting.

Unless you have an insanely complex loop you're never going to run into a problem with a D5.

well this is my computer right now. its a dual loop consistanting of gpu and cpu seperatly. found a leak on the gpu loop so i tested the cpu loop. it goes from rez to pump to flow indicator to top rad to cpu to mobo to t splitter which goes to a drain port in the front and also the rez. any help would be great

I have a similar res :)

I'm not sure what your question is, what would you like help on? Do you mean to find the leak?

I'd suggest that you remove everything from the power except the pump, and jump start the PSU using the 24 pin motherboard connector (Google how if you're unsure, or I can try explain it in words). Place plain white kitchen roll under all the places it could be leaking and when any drops hit it you'll be able to narrow down where it's coming from.
 
Oh sorry if I didn't state my question or not. My question is I feel the d5 pump lot having enough pressure or something cause when I'm doing the leak test it feels like its struggling against gravity or something
 
Oh I see, I underestimated the complexity of your loop from how you'd described it before :) Can you not just put the pump on a higher setting to see if it improves?

I'm having trouble deciphering your loop by the way. Is it two loops in parallel, one for the CPU, and one for the GPUs, but then going through the same pump and reservoir?
 
That's why I asked if the d5 pump is strong enough for the loop which I described in my previous post

I believe it's on the 5th setting already

After the first bend out of the pump the loop is going straight up. Idk if the pump cAn handle that or not

Just a heads up, but it's better if you use the edit button at the bottom of your last post rather than posting thrice in quick succession.

If you have two loops in parallel from the same pump then that will probably be making the pump work much harder than it would if they were in series.

Just to clarify, is this a problem that has developed over time, or is the loop a brand new build and it's not been up and running properly yet?

Have you got the tubes going to the correct ports on the pump? i.e. coolant going into the inlet (the centre hole on the pump), and coming out of the outlet (the port that is either off centre, or at right angles to the centre axis of the cylinder housing)

Sorry. The two pumps are completely seep rate and this is a brand new build. My first water cooling build actually and they are correct holes
 
Okay so if you have two pumps powering these loops, then the D5 should easily handle the CPU loop. Did you check that you have the inlet and outlet configured correctly?

Have you properly bled the loop of all the air bubbles?
 
When there is still a lot of air in the system pressure from the pump could be lost to compressing the air slightly rather than contributing to the coolant flow, so once the system is fully bled the flow should improve. Are you holding the cases at different angles and gently rocking it to help the air on its way out?
