![]() ![]() ![]() Quiet-PC freaks like me turn to fans that turn slower, yet still push a lot of air. Have pulse width modulation (PWM) speed control – the motherboard can control the fan speed based on how hot the server getsįans like this rely on very fast rotation speeds to push a lot of air, but the faster the blade spins, the more noise it makes.Scream at 57 decibels – not quite as loud as yo momma, but close.Move up to 150 cubic feet of air per minute.The stock fans are Nidec BetaV TA350DC 92mm fans that: I can’t run cables inside the walls since it’s a rented condo, and I can’t run cables along the floor because I’ve got a girlfriend with a keen sense of design. This wasn’t a problem when I had the server in the basement, but now that I’ve moved to Chicago and my “datacenter” is my home office closet, it’s a problem. I couldn’t carry on a conversation next to this server, let alone record a podcast. They’re temperature-controlled, so they don’t go full blast unless the server’s working hard, but even at very light loads they’re just way too loud. It’s got 6 92mm fans that can wake the dead. Seriously, the case is bulletproof and gawdawful heavy.īut it’s loud. Two quad-core CPUs, 16gb of memory, six SATA drives in a RAID 10, and about a hundred pounds of solid steel. Quest got me a Dell PowerEdge 1900 to use as a virtualization host, and it’s been great. I’ve blogged about how to build a silent PC, but today I’m tackling another noisy beast – an off-the-rack server. I like running my lab out of my office closet, but I don’t want to hear any of them running. # chmod +x /scripts/dell_ipmi_fan_control.I’ve got a few servers in my home lab and I’ve always taken steps to make sure they’re quiet. # echo "*/2 * * * * /bin/bash /scripts/dell_ipmi_fan_control.sh > /tmp/cron.log" > mycron You may have to adjust the time frame depending on your server usage. I wrote a small script, that will check the servers temperature periodically (crontab) and disables or enables the dynamic fan control based on a temperature threshold.

So basically a 11th, 12th and 13th generation PowerEdge. I tested them with my R210II, T620 and T330. These are already widely known, but I wanted to list them again. I read threads on this sub and other boards and found a lot of commands. I did some research on how to manually controlling the PowerEdge fans. There were some threads complaining about server noise in this sub the last days. r/HomeNetworking - Simpler networking advice. r/pfsense - for all things pfsense ('nix firewall) Might be able to find things useful for a lab. r/hardwareswap - Used hardware, swap hardware. r/buildapcsales - For sales on building a PC r/linux - All flavors of Linux discussion & news - not for the faint of heart!
