HI there! I have a supermicro server with a X11DPH-T motherboard. chassis is CSE-847BE1C-R1K28LPB. I’m running trunas on it.The fans are noisy. I understand I could move it to a location where it wouldn’t be a nuisance, but i dont really have that option. I dont really want to replace fans with quieter fans unless I really have to. I was just hoping there was a shell command i could run to turn fans down without harming anything? any help would be greatly appreciated
Maybe you find a solution in this thread
I have two CSE-836 chassis and found “quiet” versions of the power supplies and fans on eBay. I ordered up some and dropped my noise levels by about 50-60%. There are also some videos on Youtube that mod the chassis fans with the quieter ones you can find on Amazon. Below are the ones I purchased for my systems.

Thanks! I appreciate the help! what did you do for housings for the fans?
I was able to get them to fit in the factory housings. Just remove the current one and replace with the new one.
Nice! does the server stay plenty cool?
yes it does and runs 24x7. i’ve not had a thermal event at all after upgrades. the biggest quieting was with the SQ power supplies as the fans in the normal ones screamed. I’d suggest starting with those and moving on.
also make sure to double check your part numbers as the ones i noted fit my chassis. i didn’t confirm that they fit the CSE-847 chassis as well.
So, I’m just wondering how the system reacts to these. If they spin at lower RPMs than stock fans, does the system not try spinning them up to the speed of stock fans? Also what would happen if I got a fan controller and turn stock fans down to 1500 RPM or whatever keeps it cool?
For my CSE-847, I removed 3 of the most forward fans. My chassis came with SQ PSUs, so they are already very quiet. Thermal control from the mobo (X10SRA) handles the rest. I rarely see drive temps rise above 45 C during scrubs or lengthy incremental replication tasks to my outboard backup disk shelf. The CPU with the stock SM passive HS keeps the CPU below 50 C under load with an avg no load temp of 37 C depending on ambient room temp. The noise level is actually very acceptable for me in a somewhat used living area. A deep freezer in a nearby utility space is louder than my rack. This motherboard has some level of temp / fan control at the BIOS level, and it actually does pretty well. I haven’t felt the need to change anything via IPMI. Granted at boot POST, the fans absolutely SCREAM!

So Same chassis as me right? So simply removing 3 fans made it quieter? plus the already S Q PSU. Its hard to tell where the noise is coming from. Most of the fan noise is coming from PSU fans then?
I can’t speak to how loud the non-SQ PSUs are, but yes, removing 3 fans made a big difference for my noise levels. The SQ PSUs are nearly silent.
