I’m completing my 2nd NASKiller 4.0. This time I’m building a basic NAS backup server
CPU: Xeon E3-1260L
Motherboard: SuperMicro X9SCM-F
CPU temperature sensor always seems to improperly present that it’s at “Medium”. This causes PWM fans to always fun at a high rate even from cold boot, which is then extra annoying noise.
The SuperMicro X9SCM-F IPMI/BIOS only has 3 temperature levels that it displays “low”, “medium” and “high”. It never displays actual temperature.
I’ve fairly thoroughly tested this to isolate it to being the CPU as the issue or at least the CPU not being perfectly compatible with this motherboard.
I have a working build with a the same model SuperMicro X9SCM-F motherboard and a Xeon E3-1270V2, this works properly as expected and the true CPU temperature is communicated between the CPU and motherboard. I swapped the CPUs between my working build and my non-working build. The result is that the Xeon E3-1260L improperly communicates its temp as medium or higher and causes fans to run at higher rate. I’ve returned this specific CPU for a replacement, hoping that maybe that particular one was faulty, however the same issue occurs with the replacement.
I would have liked to use the E3-1260L for lower power, and i suppose I could try the E3-1265Lv2. However, that’s much more expensive and may end up having the same issue because maybe this issue could occur with all 45W TDP CPUs?
Is there any insights or solutions for this?
