Hello All,
I just put together a new server from an Intel P4000RP barebones chassis which comes with the S1200RPL board. On first power up it sounded like a jet engine and remained like that until I updated the bios, redetected the chassis, and did all the usual steps recommended. Now the fan speeds are totally fine when idle or under light load, but they increase to an irritatingly loud volume when running at high load.
Acoustic mode is already turned on in the BIOS, but I would like to go further as I am pretty confident I could half the max fan speed values and still be no where near overheating. The server has no hard drives, just SSDs, so there isn't much to keep cool in there other than the CPU. Unfortunately it will live in a room with 4 working people, so keeping the sound to a reasonable level is a priority even under max load. Obviously I will do some tests to make sure there is no danger of overheating.
Anyway, the issue is that I'm not sure which entry to modify. Unfortunately this being a newer board, the entries don't correspond to some of the past forum posts / tutorials I've read online. An example section from my S1200RP.sdr follows below. I'd ultimately like to adjust sys fan 1 and sys fan 4 while leaving the CPU fan settings alone. I see that "Temperature Threshold Boost Value" and "Ramp Step" are both 64, hexadecimal for 100. Is one or both of those what I need to decrease, or am I in the wrong place?
Really appreciate anyone's time and effort on this. Thanks!
