Fan controlling in both zones (CPU and HD) can be switched on and off independently. But the FANs in the zones defined by IPMI and it cannot be changed AFAIK. When you control CPU zone all FAN1-FAN4 fans will change their rotation speed (and same goes for HD zone with FANA-FANB).Alright, that's what I thought. I will try to group the fans by zone, thanks!
the fan control script needs to run via cron and at boot to set the fan speeds. The motherboard will override the fan speeds on a rebootI've set thresh holds for the correct fan sensors but I can't get the fan control to stick, any tips? Rebooted the BMC and power cycled the mobo. Do you need to be in an OS for them to stick ?
I'm just sitting in a Windows install now to copy some files off NTFS disks (unraid is being annoying because they have a windows software mirror on them) and the fan speeds keep resetting. It's ****ing irritating. Per the thermal sensors, nothing is overheating to the point that it should be triggering a reset.the fan control script needs to run via cron and at boot to set the fan speeds.

Interestingly I got threshold problems in low temperature situations (with an open window winter time) in the past, meaning the the fan reached the lower threshold value.I'm just sitting in a Windows install now to copy some files off NTFS disks (unraid is being annoying because they have a windows software mirror on them) and the fan speeds keep resetting.

Anyone have any tips? Again, the thresholds are set.
edit; so apparently I didn't read the OP article that closely, lol, but if you have anything other than "full" selected, the system will always still try to manage the fans. Yikes. So I set it to full, and applied the commands, and boom everything's great.
Ofc, you can use splitters for your fans. In the definition of the Super Micro IPMI modes:...
This motherboard only has two "HD zone" fan connectors, and four "CPU zone" fan connectors, but given the descriptions in this thread and the massive differences between my fans I don't think I want to put them all into the CPU zone. Would I be better off getting a PWM fan splitter so that I can connect all three case fans to the "HD zone"?
You may read the very first post in this thread for better understanding.Where did you get this info?
I have similar motherboard, the X11SCH-F, and there's no mention about this in the manual besides dual cooling zones. I have no idea what that means.
You may use ipmitool remotely since IPMI/BMC is an independent subsystem. You can configure things from a different Windows or Linux PC.Yea I have since noticed.
But anyway, is there any way to set the FAN speeds on a server running ESXi? There's no ipmitool.
Those scripts were created for local execution indeed, but you can hack ESXi with ipmitool remote access if you really want to.Oh, ok.
But I am slightly confused with the first post/article. The author says he has a script apply the settings every time during boot.
Setting up IPMI fan control mode, or fan thresholds are persistent configurations. If you configured once they will stay while the BMC is not reset.I mean, do I have to apply those settings on every boot of the server?
