October 10, 20205 yr Hi all. This is long overdue. My Lian-Li build has had fans on constantly for years now. I’ve always meant to look into why, but thought it was probably just it’s environment (in a large cupboard under the stairs). But we recently opened up said cupboard to change its configuration and haven’t noticed any change in temps or noise. Build: LianLi q25b ST30SF PSU 2 Gelid silent pwm fans ASUS H81I-Plus motherboard 8gb ram 120gb ssd 4x 3TB drives (WD greens/reds) i5 4670k Applications: usual plex/nzb dockers home assistant vm Average drive temps are 45C Cpu is 48C at 6% load Fans are 2700 and 860 rpms Im open to suggestions. It’s just something I know very little about. If it’s a software tweak, or a hardware change, just throw ideas at me. When we build up the under stairs again I’m going to have a little area at the top. So I might install in and out vents under there to bring the temps down if I can. Thanks for your time.
October 10, 20205 yr Does filter install at FAN, pls ensure they are clean. And better provide est. surrounding temperature.
October 10, 20205 yr You means no any dust filter in Q25b ? Case have 5 disk slot, pls empty the middle slot for 4 disk install. BTW, temperature reading not abnormal high, surrounding and case temp are key factor. I even haven't install case fan in Lianli Q11 for a standard 65w CPU. ( Always light load ) For about noise, If FAN at 2700 then it will be the source. Edited October 10, 20205 yr by Vr2Io

Your motherboard supports PWM fan control if enabled in the BIOS and the fans are connected the the fan headers. There is only 1 header for CPU and 1 header for Case fans. If the fans are connected directly the PSU, you either need to buy a fan controller, a low noise adapter (basically a resistor that connects in line with the cable), a fan with a lower speed or switch to PWM (4pin) fans. I've used ARCTIC P14 PWM PST (120mm) and ARCTIC P12 PWM PST (120mm) fans as these allow you to piggyback a connector onto a single header.
October 11, 20205 yr Author Thanks. I honestly can’t remember, but I’m sure I connected to the header on the motherboard. I’ve checked ambient temp, it’s 25c a few inches in front of the case.I’ll check my fans and your suggestions, although it’s a pain to get to bios as I have to rip it all out and connect it to my tv. But I’ll have a go.I was going to upgrade the case and move to Matt for a graphics card, but apart from plex hardware decoding, I no longer have much of a need for it (I was going to do some 3d work at home, but now I can just vpn into the studio thanks to covid). But a bigger/better case would have given me better airflow.Sent from my iPhone using Tapatalk
