Currently Unraid server sits on a Supermicro X10SRA-F with a Xeon E5-2640 v4. This has been rock solid for my use case over the last 7 years but now I am getting rid of pay TV (will still have Amazon Video plus the streaming services I get free with TMobile) and instlaling an OTA antenna. I will be running the Antenna to network tuners (I have 3 HomeRun CONNECTS that I bought several years ago when I was considering doing the same thing, will just use those for now and may upgrade later.) I will then be setting up an OTA DVR on my unraid server (likely Plex, seems to be the best option with what I will be streaming to.) The TDP on my CPU isn't awful, but I am still thinking the power consumption benefit would be there for the inconvenience of replacing my motherboard, CPU and memory as any GPU I put in that will handle transcoding (even though not conerned about 4K streams right now I want to future proof) will consume a significantly larger amount of power than upgrading to and Intel processor that is iGPU quick sync capable. I am thinking something along the lines of a 13500 would be my best bet, offering the capability to easily transcode 4 4k streams simultaneously and not impact me performance for the other tasks the server is performing over my current E5-2640. This would also reduce my over all power consumption rather than increase it by adding a GPU. The only thing I am really giving up is the registered memory. Does this sound about right, or am I missing something?

Problem with the bios controlling the fans is that it can not key off hard drive temps.

The script as I have been using it is attached. One note, it seems the X8SIL-F has a built in fail safe as mentioned in one of my previous posts. I initially thought it was just on fan port 1, but it is in fact on all the fan ports. If you set the fans too low, the motherboard will kick PWM back to automatic and the fans will go to full speed. This happens pretty quickly, so it is easy to test and find out where the limit is. unraid-fan-speed.sh.zip

Been using this script for 5 days now with good results. Definitely a good option for anybody using an X8SIL-F with PWM fans. The 3 120mm deltas I replaced the 4 stock 80mm fans that came with the Norco 4220 run quieter then the other equipment in the room 80% of the time. The other 20% has been running at the medium speed which isn't at all bad either. It has not yet needed to kick the fans up to full.

I have been playing around with this script a little bit on a Supermicro X8SIL-F-O. The fan speeds can be set through pwm2, but it would seem that the implementation has a fail safe built in. If I try to drop the fan speed too low (100 is fine, but 50 or 0 are not), pwm2_enable goes from 1 to 4 (which is apparently automatic) and the fan speed kicks back up. I don't think this will be too big of a deal, but was curious whether I am missing something and there is a way around this. Edit: It seems this is only a problem if there is a fan plugged into the first fan header. The other 4 don't exhibit this behavior. So likely a built in fail safe for the CPU fan.
