So I have already purchased all the components and I should have asked this question sooner but...

I want to use 18 2200 RPM PWM fans that have a current draw of 2.16 W each. I don't plan to use them at that speed most of the time. They will be hooked up to a 3 way PWM splitter for each fan header on the motherboard. I also want to use 2 D5 pumps with variable speed control. that's a total of 8 fan headers needed. (I think)

My question was, should I have purchased a PWM D5 pump instead of the variable D5 pump? Can I still control the variable speed D5 pump in Fan Expert 3?

Also, am I making a very big mistake somewhere in my build?

Thanks for advice in advance.

18 fans sound alot - you are going to run 2 loops, right? what case are you using and what size radiators. I believe that you don't need to control the pumps and fans. Setting the pumps to flow at about 75-80% should be constant. Your fans can be controlled with Fan Expert . The biggest thing is planning your loops - draw it out first and make sure you have space to work even after you have installed the loops. Have a good and easy draining system. Then just worry about how good you want to make it look - a good water-block for your cpu is also recommended.

I plan to run a Sportswood compact workbench and 3 360 radiators in push pull. I am cooling one CPU and 3 GPU's. (possibly 2 GPU's) I plan to do just one loop with 2 pumps. I still should attach the pump to the motherboard header right? Would the pumps variable speed control override the Fan Expert 3?

It's gonna look like the triple stacker one.

How are you going to run the loop - Res - pump - cpu - radiator - gpu'S - radiator - back to the res? where are you putting the 3rd radiator - then the dual pumps - where are they - i would run with a XSPC Twin D5 Dual Bay Reservoir Pump Combo - if you place two pumps independent in one loop - and control both I believe could cause huge problems, I would not risk it, but because your loop is long you must use a dual pump system, to keep the pressure and flow - I would just connect the pumps to my psu and not control them over this distance -

Thanks for the reply. I got a EK D5 dual top with Res on top. They are going to have a base that they can sit on anywhere connected to the bottom outside of the case. I haven't quite figured it out yet but I was thinking...

Res - pump x 2 - bottom rad - botoom rad - middle rad - CPU - GPU - GPU - GPU - back to the res.

Or

Res - pump x 2 - bottom rad - bottom rad - CPU - GPU - GPU - GPU - middle rad - back to Res.

Ok I will just connect the pump to the PSU and not hook it up to the mobo?

always have it going to a radiator before going back into the res - I don't really know if running it through the 2 radiators in the beginning will make a huge difference - I would tried to do cpu - radiator - gpu's - radiator to get the temp down before going through 3 gpu's - after 4 components the fluid will get pretty hot - you can connect the pumps to the mobo if you want to see what they are running at, but would not control them.

I see I see... Very Good advice. I am glad I asked then. Thank you.

if the fans go over 1A in total per fan header, forget connecting them to the mobo fan headers.
best would be a fan controller TBH.
and if i was you i would get a temp probe to the loop to monitor the water temp.

pump/res -> cpu -> rad -> gpu's -> rads -> pump/res.

I am asking EK what ampere the Vardar 2200RPm 's are now. I cant seem to find the info on the interwebs.

1A to watts calculation with voltage of 12V DC

For DC power supply, watts are equal to amps times volts.

watts = amps × volts

watts = 1A × 12V = 12W

So I should be under 1 ampere with 3 fans to one header I beleive.

The X99 deluxe comes with one temperature probe but how would I set it up to the loop? Should I tape it onto the outside of res or something?

Also I have one more extra 360 rad that I can use ontop of your sudgestion.

Thanks,
