Hello. I have a X470-F based system that is water cooled with a custom designed loop. In the loop is a Koolance INS-FM16 paddle wheel flow meter which is a good visual indicator that the water is flowing. I just added a ADT-FM03 frequency adapter which multiplies the very slow frequency of the paddle wheel output to a frequency on par with a standard fan, and connected it to the CPU_FAN monitor input. The obvious goal is to cause a shutdown of the system if the water flow ceases, such as if there is a pump failure. However, there is an inherent delay as the pump starts up and begins to move the paddle wheel. The CPU fan monitor is causing a boot failure to BIOS because it is not seeing a valid fan input soon enough. A 2-3 second delay in fan detection would solve this problem.
Has anyone had this problem, and how did you solve it? Thanks.
