Admit it, you'd fashion some fancy chrome knobs on it.

i did leave off building it yourself you're right.

beautiful work as always.

Tbh I have a d5 Vario and it’s really difficult to reach back there and mess with the setting...so I need a way to regulate it without reaching back there.

And I got it set up. It works. I’m Testing now to make sure my house doesn’t burn down.

That'll probably work out OK.


The D5 has a fairly sizeable electrolytic cap on the power feed, so it's going to integrate the pulses and act more like voltage control electrically than actual PWM, but as long as it works, is what counts.


A number of folks used high power variable voltage fan controllers to vary the speed of the Vario D5 with the red adjuster set at 5, so the interesting thing is going to be to see how much range of control you can effect.


Been a bunch of years, but my best recollection is that you could slow the D5 down to about 7.5V, but it wouldn't start with less than about 9V, and the usable RPM range was somewhat less than you could slow it down to with the red adjuster set at 1 to 2.




I did try a similar idea with a pair of D5 Strongs on a PWM controlled 24v supply, and while the D5S has a top rpm of about 6100 with a 24V supply, I could never get it to run reliably below about 3800-4100 rpm


Keep us posted on what kind of speed range you can get, and what minimum speed setting you can get it to reliably start at on power up.

I was able to control it quite a bit. I had it connected to an external psu and it was working fine. I got a decent range. Yes I had to turn it about halfway (6-8v I suppose) before I saw any action, but I was able to get the full speed at 5. I’ll try connecting my multimeter to see exactly what voltage I’m getting out in a bit.

I need to get a better case for this thing because I used double sided tape to mount it in my case and connected it to my internal psu...and it shorted when I moved the case. I guess there was some contact with metal...it came back online in a few min but I had this sort of thing happen before too. I’m wondering what it could be...

If you connect a 75W rated potentiometer to a device drawing 24W from a PSU rated at 750W max, you shouldn’t have issues right?
Trying to eliminate sources of error.

Where did a potentiometer come into this?


Are you looking to put it in series with the pump to reduce the voltage going to the pump?


You size a potentiometer by the resistance you need to do what you want to accomplish with it, and then specify a power rating, (W) based on the worst case power drop across the potentiometer.

A voltage regulator is a potentiometer, right?

Yes. I have it set up so Power goes into the potentiometer from the psu and out to the pump to reduce the voltage going to the pump.

Power drop worst case is 24 watts so I guess my equation is (P=V^2/R) = 24W /144V = 0.166kOhm?

About to embark on another water cooling journey soon. Just waiting for more components to arrive.
