Zitat von »Shoggy« The alarm header only sends a static tacho signal as long as the electronic says the pump is OK. So it is just a "I am alive" signal and can not show the real speed. Yeah, i've figured it But are there any way to send real pump rpm to cpu fan header? I need this to make my Asus Front Base show realtime pump speed which it reads from cpu fan header. I know pump rpm signal goes through aquabus and usb cables which uses their own signal protocol.

Hello. Are there any way to send correct pump rpm value to cpu fan header of the motherboard? Using 3pin alarm header of the pump gives wrong rpm signal. Here's screenshot: on top is the correct pump rpm and on the bot is rpm sent from alarm header of the pump to cpu fan header:
