Build’s Name: Chess Workstation / Home Edition
Operating System: Windows 10
CPU: Dual E5 2683 v3, CPU-coolers: 2x Noctua U9DX-i4, standard front to back fan orientation, low noise adapters
Motherboard: Supermicro X10DAX
Chassis: Supermicro SC732D4F-903B, Mid-Tower. Case fans: 1x exhaust case fan SM 12 cm (came with case), 1x intake Noctua 12 cm.
Drives: SSD, Crucial MX200 - 1TB
RAM: 128 GB, 8 x Crucial 16GB DDR4 2133 ECC
Add-in Cards: Asus NVIDIA 760 mini
Power Supply: PWS-903-PQ, 900 Watt, 80 plus Gold (came with the case)
Usage Profile:
Extended chess analysis, using standard chess GUI and chess engines, e.g. Stockfish 7 and Komodo 10. Optimal analysis with chess engines typical uses all CPU resources. System should be stable under full load 24/7 but still be relatively quiet, as the box is sitting in a living room/apartment.
Build and Performance:
Build was easy, system is performing to specs, 3300 CPU-score in Cinebench R15, Chess benchmark: Stockfish chess engines >30'000 kN/sec in base chess position (multithreading off, as suggested for chess analysis). Typical max core temps under extended full load are stable at 54 C and 64 C for the 2 CPUs, CPU fans spin at 1300 RPM, case fans at 950 RPM
Noise Levels:
System can be reasonably quiet even when under full load from chess analysis, exhibiting moderate levels of typical low frequency fan noise, but only if side panel is off/removed. PROBLEM: when the side panel is mounted and system is under full load (as it will be most of the time) noise level increases slowly by about 10 dB (guess using a phone) as opposed to full load and no side panel mounted. The additional noise is annoying and distinctively different from the CPU fans and case fan noise. Opening the side of the box halfways, giving the PSU breathing space, eliminates the noise problem.
Other observations: Side panel mounted/off does not influence core temps or fan RPMs. Disabling the CPU hyperspeed options in the BIOS the X10DAX to reduce power consumption did not help. My guess: the additional noise seems to come from the PSU/PSU fan, due to a combination of relatively high load and and high ambient temperature.
Any ideas how to reduce or eliminate this additional noise? Some ideas: (1) Replace PSU (costly, outcome uncertain) (2) mod the case and flip the PSU on its back to let it take in fresh air from the top (add dust filter), (3) mod the side panel and add an intake fan to the side panel (4) simply use the system without side panel.
Thank you.
