Good to know!Just as a FYI - the lowest Xeon D CPU is spec'd for 80C but most of the storage/ networking/ and etc SKUs are now spec'd for 85C-96C operation since Intel is targeting embedded applications.
This is so key I think. With my D-1537 direct airflow makes about a 30C difference. With a duct blowing one of my 80mm fans directly at the CPU I'm getting about 52C idle where as with no duct my temps go up to over 80C.Not a D-1541, but...
This weekend I moved my X10SDV-TP8F (flex-ATX D-1518) from the 1U SC113 chassis I tested it in to its more permanent SC113M. Temperatures rose from a comfortable 38C idle t0 a more worrisome 65C (still idle). I haven't even tried to run it up to load to see what would happen.
The key differences are (1) no airflow shroud present in the SC113M and (2) lower airflow fans - the SC113 had 4x duplex 40mm fans (FAN-0086L4 40x56mm) vs the SC113M with smaller simplex fans (FAN-0065L4 40x28mm).
The fans in the SC113 sat at low-speed (5400RPM vs 12,000 RPM max) to get the 38c idle.
The fans in the SC113M sit a little over half speed (8500 RPM vs 13,000 max) to get the 65c idle.
I think the big difference is the shroud. These D-15xx motherboards seem to absolutely need directed airflow over that (probably too small) heatsink.
I've ordered a shroud for this older recycled chassis - I'll update when it arrives later this week.
@PigLoverI got the SM 1U shroud for the SC113, After installation the idle temps dropped to 45cC. Amazing the difference a bit of directed airflow seems to make on this little low-power CPU.
@PigLoverFans have dropped to ~5k RPM, which is the slowest the Supermicro BMC will let them run.

I must have missed that post, do you have a link to this mod?I'm running an X10SDV-8C-TLN4F with Patrick's Noctua mod and getting idle temps around 50°C and load about 71-72°C. Is that normal/typical? What temps are people generally getting on these Xeon-D's?
