Hi All,
I've been doing a bit of reading on how to use impitool to adjust the fan thresholds on my motherboard, to prevent the spin up/down issue that some people have previously reported.
The basic steps I took were as per Decrease Supermicro IPMI Fan Threshold
This MB has 5 headers, FAN 1, 2, 3, 4 and FAN A. In my chassis, I have my CPU cooler fan on FAN 1, 2x 120mm chassis fans on FAN 2 and 3, a 90mm chassis fan on FAN 4 and another 120mm fan on FAN A.
What I am finding is, with my thresholds all set the same as per the above mentioned link, if I have the 90mm fan connected at all, it reintroduces the cycle up/down issue I was seeing before.
I suspect this is because this fan has different RPM limits compared to the 120mm fans, but I can't wrap my head around how to adjust the thresholds accordingly so that I can have this connected with lower than default thresholds and prevent the spinup/down issue.
Can anyone assist me in tweaking the IPMI thresholds to accomplish this?
Thanks
Eds
