The current information in my database provides me few information in regards to the BXTS13X Liquid Cooling solution. I am going to work with my upper manager in order to get an answer to your questions. Please give me a couple of days.
1) The Speed will vary depending on the temperature reported from the processor to the motherboard. Speed range 800 – 2200RPM (PWM)
2) The cooling solution does not have a built-in sensor. The processor has sensors and it will send the signal to the board.
3)The Cooling solution uses the Fan header in the mobo. The pump pressure is the same always.
I appreciate your research, thank you.
Just to confirm:
The fan relies on the motherboard fan header to control the fan speed in response to how warm the processor is - just like a regular heatsink
The pump unit is not modifying the PWM signal - just passing it straight through to the fan.
The pump simply runs 100% full time and only uses the power from the motherboard fan header - it ignores the PWM signal.
