Pump and PWM

Hello

I have 2 pump D5 PWM (the same) plugged in PWM on the 4pins Water Pump of the R5E10 (blue and yellow file)
Can someone explain me how the PWM works on the R5E10?

Example

60589

I do not know if for 30° for example, it is up to 30°, from 30°

And for Middle and Max ?
Is the PWM related to CPU or CPU Package temperature ?

Thanks for your help
Sorry for my english 😄

You have three settings pretty much.

The top is the temperature your CPU will hit when you want your pump to work at 100%. The second and third are the same way. I have the bottom one set on mine at 60% which means pretty much when my computer starts up and as long as the temp is below 50C my pump will run at 60% speed. The middle one I put at 75% for when my CPU temp hits 65C. The top one is if my CPU hits 66C the pump will run at 100%. Of course different people will set their pumps at different rates. Many keep it running at 100% all the time. It is really up to you. I have mine running at 60% most time because it is dead quiet at that level and unless I'm gaming I don't need it to run faster.

OK thanks
That's how I set up, but after a while, in idle, I was found with the pumps less than 20% (I think) while the mini was at 60% and 35°
Can be a bug

Otherwise I have the 2 pumps on the same 4pin (Water Pump) connected with a Y
It is better that each pump is connected to a 4 pin or not important ?

Thanks

Hi Tistou.

I have also 2 pwm pumps (alphacool previous version to latest ones just released) in my RVE, each connected to one 4 pin (cpu and cpu opt) and their respective molex's.

The pumps will reach rpm's according to cpu temperature, if you have a minimum of 30 degrees and 40% for example, the cpu at 30º will make the pumps run at 40% (of 4800 rpm's máximum).

But sometimes when rebooting, I found that RVE (and also RV10) did not manage to control the pumps correctly, letting them almost off and even forcing the bios to show the cpu temperature warning.

Check your "y" cable just in case, and verify the connections are ok.

Best regards!!! 😉

Hi

Thanks for your help
And thanks for confirming CPU temperature, I was not sure it was related to that one

The pumps are well connected, I have a flow meter and it is good
I will leave with the Y on the 4pin Water Pump

I regulated like this in the bios

Mini: 60% / 35° (if I set to 30°, even with the CPU at 27°, I'm at the higher speed per moment)
Middle: 80% / 50° (the pumps are between 60 and 80% up to 50°)
Max: 100% / 60° (temperature does not exceed 50° with current ambient temperatures)

As the other mate mentioned, you have 3 temperature points, max, medium, min and their respective rpm percentages.

If you have max 70-100%, 50-80% and 30-50% for example, the cpu at 30º will run at 50%. Over 30º and until 50, it will increase to 80%; over 50º the same until 70, when the rpm's will be maxed reaching 100%. I am not sure which specific temperature is used, I would bet it needs all the cores over the checkpoint to reach the selected percentages.

In regards to the failure I mentioned, I saw it used to show up when selecting close percentages, for example 70-100%, 50-90%, 30-80%.
