Even in full fan mode, I can't get my 6028U-TRTP+ fans to go HIGHER than 9k rpm. Anyone else have this issue?
I have tried forcing it with raw IPMI commands, along with rebooting and resetting the BCM but it always tops out at 9k.
I have other SM servers X9/X10 and they have no problem hitting 20k+ rpm when in full mode but this particular server seems to be getting limited by something and I am stumped. Is there an unlisted jumper or setting somewhere limiting this?
I would be curious to hear if anyone else with this model is able to get faster fan speeds.
Edit: I'm an idiot. I finally took a fan out and Googled the part number. It turns out the fans have a max RPM of 9K.
I should have done that in the first place but I just assumed the max RPM in the IPMI matched the actual fan limit.
