I also have 8 HDDs. I checked my drives physically, and they are mostly Seagate LPs, something like low power. I have Seasonic PSU, with fan intake also at bottom of the case. Front dust filters are also installed. The pictures I'm showing are either from my Unraid Dashboard, or IPMI Plugin I installed. I am also running out of options as of now. I never thought adding new fans to cool down the drives will be such tedious. Please don't give up on me yet guysJust to clarify my setup I have two fans cooling the 8 hard drives in the storage compartment of the case, both Fractal Design Silent Series R2 (intake is 120mm, 1200RPM in the upper position and exhaust is 140mm, 1000RPM at the back) connected to the motherboard fan headers of a Supermicro X10SLL-F and the fan control mode set to "Optimal". The front dust filter is installed, and the power supply underneath the drives is a Seasonic G550 with the fan intake at the bottom of the case.
Your drive temps are really odd if they are low power/green, unless your ambient temp is super high. What are you using to read the drive temps?
K D, I'm using Supermicro X9SCM-F motherboard, and using Xeon E3-1240 V2. Sounds like a plan. I hope it works. Will do it another day since it's late. Thanks for keeping hope aliveLooking at some of your screenshots, it looks like you have a SuperMicro board. Please confirm the motherboard and CPU. If so, try these steps
- Connect your CPU and fans on the motherboard side to FAN1 - FAN4 headers on the motherboard.
- Use a Fan splitter cable to connect all 3 fans marked in Post #4 by @marcoi to connect to FANA header on the motherboard.
- Reset your BMC to factory defaults. (Maintenance -> Factory Defaults -> Reset)
- Once the BMC comes back online define the fan thresholds manually with the commands 1 and 2 below.
- ipmitool sensor thresh FANA lower 200 250 300
- ipmitool sensor thresh FANA upper 1300 1400 1500
- This should set the thresholds for the 3 Noctuas
- Restart your BMC (Maintenance -> Unit Reset -> Reset)
- Set the fan speed to Full
K D, where do I execcute IPMITOOL RAW commands? Do I ssh into the BMC IP address?See resource by @PigLover at Supermicro X9/X10/X11 Fan Speed Control
You can use IPMITOOL RAW commands to set cpu zone and fan zone speed independently now that you have hooked them up correctly.
40c avg at idle is still high. I try to keep temps at low 30s during idle. It could be that the P12s are not enough. Alternatives that I'll recommend are Arctic F12, Noctua F12 or even better Noctua iPPC 3000.
He's talking about the cooling zones on supermicro mainboards:Additional question: What do you mean by now that fans are connected corretly?
Additionally, The noctuas at full speed dont seem to be enough to cool your drives. So reducing their speeds is not going to help cool the drives. Looks like then fractal fans helped and you are set now.At 750 RPM though, Noctuas won't be enough to cool my hard drives. In the end, what cooled my hard drives are the original fans that came with the Fractal case, all 3 of them connected to the HDD side. All those fans have 3 pins, that I connected to the fan switch that came with the case, set to High. That took care of the fans blowing the HDDs. Since I have a dedicated CPU Fan, the motherboard side of the case, with Fan A (Noctuas) blowing at low speed, it doesn't really get hot.
