July 5, 201313 yr I have the following MB/CPU: Supermicro - X9SCL/X9SCM Intel® Xeon® CPU E31230 @ 3.20GHz - 3.2 GHz (Retail - CPU/FAN) and the CPU Fan is only running at 2000 RPM and the MB still warns me of CPU temp overheat - right now its at 36C should this CPU fan run faster than 2k or do I have a fan failing? Opinions please... Thanks Myk
July 5, 201313 yr 2000rpm is the base fan speed for a stock Intel heatsink. 36 degrees with a Sandy Bridge E3 with a stock Intel heatsink with the fan running at 2000rpm in the summer time is perfectly reasonable. Not sure why you're getting overheat alarms. Where exactly are you getting these alarms?
July 5, 201313 yr As mrow noted, 36 is a VERY reasonable temp for your CPU, so you should NOT be getting warnings. Check the BIOS thermal control settings ... fan control, temperature alarms, etc. You may have somehow set the alarm threshold far too low.

Thanks for looking Myk
July 5, 201313 yr Author I looked for alarm threshold the other day and didn't find anything, granted i didn't have much time and looked very quick. I will look again tonight when I get home from work. Thanks Myk
July 5, 201313 yr Hopefully this will prove to be a simple case of a miss-set alarm threshold. Definitely strange !!
July 8, 201312 yr Author Ok, spent hours last night to no end - there is no alarm threshold settings in my bios, current version is at 2.09 I got the lastest bios (2.17 i think) and made a bootable flash drive, books just fine on my windows machine, but for the life of me I can not get it to book on the unraid box. So I have to figure out another way to get something booted. My windows machne can falsh from a non bootable flash drive using its F key during boot. Why does supermicro no do the same. They make it so hard to update ANYTHING.... Suggestions? Myk
