While having fortnite up I decided to see how slow I could run the pump and have it still hold the CPU temp at 104F.
I used a variable voltage DC supply and connected the ground to the ground on the power cable the pump normally plugs into so that the tach would work properly.
I found that I could greatly reduce the pump's speed while keeping the CPU temp steady.
Are there any higher current pump controllers that take the standard 4 pin molex plug for the input and pump output?
I'm tempted to use a LM-317 variable voltage regulator with heatsink and a variable resistor to control the voltage but that is a bad way to do it in my opinion if there's a proper controller out there as I don't want to risk damage to the pump board.
EDIT:
I ordered this.
12v to 5v Buck Converter, DROK LM2596 Adjustable DC Voltage Regulator 4-40V 24V Step-down to 1.23-37V 12V Volt Reducer Board 3A Power Supply Transformer Module https://www.amazon.com/dp/B078XQ5MW...t_i_SMAAZFXTWT9W7KVQR9ZS?_encoding=UTF8&psc=1
That way I can set the coolant flow rate to what is needed to keep the CPU cool.
When I upgrade the video card I'm going to see if there is a water block for it and if so I'll use that on the card.
The motherboard video. Since it's disabled in BIOS does it still need a fan on it?
