Wow, thanks. Much better than ipmitool.
Can someone comment on what the 300 300 400 numbers refer to? The reason I ask is that when I look at the fan sensor thresholds on my board (X10SDV-7TP4F) it shows me 4 values not 3. They are Low NR, Low CT, High CT, High NR.I've built a Supermicro Avoton NAS with two Noctua NF-A9 PWM and one Noctua NF-A14 PWM. Also had the fan problem but configured the RPM thresholds according to the fan specs like this:
ipmitool -I lanplus -H nas-sol -U ADMIN -P ADMIN sensor thresh FAN1 lower 300 300 400
ipmitool -I lanplus -H nas-sol -U ADMIN -P ADMIN sensor thresh FAN2 lower 300 300 400
ipmitool -I lanplus -H nas-sol -U ADMIN -P ADMIN sensor thresh FAN3 lower 200 200 300
docker run --rm -it ubuntu bash
apt-get update apt-get install -y ipmitool ipmitool -H "<IPMI IP>" -U "<IPMI USERNAME>"-P "<IPMI PW>" sensor
ipmitool -H "192.168.1.81" -U ADMIN -P "..." sensor thresh FAN1 lower 100 150 200 ipmitool -H "192.168.1.81" -U ADMIN -P "..." sensor thresh FAN2 lower 100 150 200 ipmitool -H "192.168.1.81" -U ADMIN -P "..." sensor thresh FANA lower 100 150 200
Maybe an old thread, but yes, I believe this is the solution. For example a Phanteks PWM Hub Controller uses the SATA 12V connection to the PSU as the power source, and then connects a 4-pin PWM header to the motherboard to receive the PWM signal. Then case fans are connected to the fan controller hub and are accordingly increased and decreased in speed as instructed by the PWM header from the motherboard that is responding to thermal/temperature of the environment (usually the motherboard temp). However, the important aspect is that motherboard PWM fan header is not being used to power the fans, but merely to instruct the the fan controller to spin up and spin down the fans.Another option (although a bit more expensive) is to use a fan controller that is capable of handling high-wattage fans, such as the Aquaero 6 which has 4 PWM channels that can handle up to 30W each. The version I put in my SC846 is at http://shop.aquacomputer.de/product_info.php?products_id=3092
I put the front 3 fans each on their own channel and put the rear fans together on the 4th channel. The LCD panel is removable, so I took it off and mounted the fan controller inside the case and connected it to an internal USB header.
The software included with the controller lets me set a custom fan curve for each channel based on temperatures from the thermal probes connected to the Aquero or based on temperatures reported by hard drives and the CPU. It is a bit expensive but very customizable and with it, the case is nearly silent when idling with SQ PSUs installed.
Which fan controller did you install? TIAThank you sir. I've quit for the day and am now chillin' with a beer. Will give it a try in the morning.
I did hook up a fan controller just to see if it would work and it does. I put 2 humongous Scythe fans in it and can control the speed from silent to wind noise, not too loud but can be heard. And no more oscillating between low and full blast. The reason for all this is because my CPU temps are on the high side, upper 50's at idle. I've got a pair of SM active coolers on the way. Seems these Dynatrons just can't cut it. Right now one is a 42 and the other is at 50. That's with the 2 Scythe's barely audible. Temps drop even more when I crank them up. I'd rather have the MB control the fan speed but I'll settle for what I have if need be. The dynatrons are very quiet, can barely hear them when the room is quiet, but they just don't cool very well. The 2 Scythe's are awesome fans, they push a tremendous amount of air and do so as quietly as it gets. Highly recommend them.
