Dell XPS 13 9350 fan noise even at light tasks
Hi,
got a Dell XPS 13 9350 (i7 iris 540 / QHD) and was pretty excited.
Installed all updates (driver/BIOS,....) and even did in right order for WD15 dock.
Only Chrome and Steam installed.
There still seems to be a weird fan control issue with this device:
- Fan stays quiet (off) when doing nothing or only browsing the web. (+/-52°C)
- Watching Youtube (even 720p only) and the fan kicks in after the device gets heats up. When unplugged the temps are about 70°C when the fan starts. Noise is very annoying even at lowest speed. I don't know why a high end device like this isn't capable of doing basic tasks cooled passively. Even a FireTV Stick , every phone or Raspberry Pi can do this. So very disappointed.
- When plugging Dell WD15 (USB-C) dock into the XPS 13 (external monitor, GBe, USB, Charging via USB-C) the temps raise from 50°C to 60°C immediately. Fan starts earlier at +/-60°C. Why?
The fan cools the device to 49°C and then stops for a while, starting again at 50 or 55°C. I can't see a pattern. When doing light tasks (Youtube 720p) the fans run constantly and may raise to >70°C.
XPS is in this case always loud and my main complaint.
- When playing games with attached WD15 dock the fans are at full speed (very loud). This is expected, as the heat must go away somehow.
- Already tried many different energy settings (balanced/quiet/....), but the fan control stays always the same.
Read about a BIOS update 1.20 for Dell XPS 15 at "WD15 FAQs", where the fan control seems to be optimized with WD15 dock use.
I'm hoping for a XPS 13 9350 BIOS fix to optimize fan control with WD15 dock and even fan hysteresis.
My suggestions:
- XPS 13 fan should start at a later temperature measurement, to be able to do light tasks without fan noise.
- XPS 13 fan should start at a later temperature measurement when connected to WD15 dock. Seems the fans start more often when the device is charged, so when using USB-C dock it's always the case and not user avoidable. Dell please disable this behaviour!
- XPS 13 fan should stop earlier again (eg. colling down to 60°C and not <50°C)
Dell Command Power Manager "Quiet" setting doesn't change fan control in comparison to "Optimized" setting. So why call it "Quiet"?
I really like my XPS 13, but the fan noise is making me angry after 2 weeks of use. It's not useable for continuous work. :emotion-6:
Already reset BIOS to defauts, did a Windows 10 recovery and ran Dell diagnostics witout errors.
Don't know further helpful steps.
Please help.

Today updated XPS 13 to BIOS v.1.4.3 (including USB-C controller update).
The temperature seems to be a bit lower now with Dell USB-C WD15 dock.
The fans start at the same temperature, and seem to run for a longer time until <40°C.
So fan is always on practically. :(
