Help with Pump choice

[Yatys 93]

Hey all

 

So I am planning a liquid build in the future, not any time soon as the price list has past £5000 right now, and that is going to take a little while to get together, its going in a 900D and will be mainly hardpipe bar in the basement to make it a little easier to link everything down there, my question is will my pump be strong enough to work with my build.

 

Parts are a 60mm 480 rad, a 60mm 240 rad and a 30mm 480 rad, a EK supremacy CPU block, a EK X3 250 res and 3 GPU blocks, at the moment I am thinking 3 Fury X's with the full cover EK blocks, the Pump at the moment is the D5 PWM from EK (Link https://shop.ekwb.com/ek-xtop-d5-pwm-plexi-incl-pump ) although not sure if the PWM or the Vario is the better option, although I do know the PWM version can be a pain to initially fill the loop. 

 

Thoughts?

The D5 pump would be a great option, the PWM or Vario version is mainly a matter of choice if you want software controllable pump speed but I find for the vario just leaving it on the lowest speed works great and you can ramp it up during initial fill/bleeding with the little dial.

I'd go with the Vario. Best to be able to fix it at a speed that you like from a noise standpoint. Changing the speed of the pump doesn't effect temps much, if at all, so there's not a lot of point in having the PWM.

With that many restrictions, wouldn't be a terrible idea to use 2 D5s....they're not known for their head pressure....

I'm not sure where you got that from but D5's have amazing head pressure and flow, it's capable of ~4m or ~12ft of vertical head pressure.

The D5 has great flow rates and average head pressure.  The DDC has great head pressure and average flow rates.  In high restriction loops, the DDC is the better option (unless you go with 2 x D5s).  In low restriction loops the D5 is the better option.  I run 2 x D5s in my loop, because it has a lot of restrictions.  Well, and I prefer the D5 pumps.

The difference isn't that much but yes the DDC does have even better head pressure to the D5 but both aren't what I would consider bad by any means.

Noooo, neither of them are bad.  Just that in a loop with a lot of restrictions, I always prefer to steer on the side of caution, rather than not, and end up sorry I didn't.  /shrug

4 water blocks isn't that much restriction. even with VRM and RAM blocks the

single D5 is still the best option. dual for redundancy and epeen.

I assume if I were to add 2 pumps, I would fill using the first pump until the loop is fairly full then power the second on up to avoid damage?

You can basically use the pump closest to the res to fill the entire loop and then run both once everything is good, or do both at once as long as they both get fluid.
