Dell Optiplex Cpu Fan Control

Your dell pc may contain several fans to keep the internal components cool.

Dell optiplex cpu fan control.

Tried the alt mode next and it then runs full cpu clocks. However it seems that while its disabled the cpu frequency refuses to go over 1 39ghz. Temps go to near 100 but then cools by throttling the cpu. In this video i walk you through taking apart and turning the cpu fan around so your computer stays cooler.

The only thing is the noise of the cpu fan with is very noisy for a business device such this. Dell does not support 3rd party software. Go to utilities partition and run the fan diagnostics. Desktop pcs have more than one fan processor cpu dedicated or discreet video card gpu power supply psu and one or more chassis case fans.

Because of this the processor heats up to 100 c and its throttling reaches 30 until a sufficient increase in fan speed occurs 1 min. The system is brilliant so far. Tried running cinebench after disabling the ec fan control. Lint and dust accumulation prevents air from flowing around the cooling fins and causes the fan to work harder.

I bought a brand new dell optiplex 790 with ssd 8gb ram and i7. Cpu fan to full speed at startup before settling down to normal operating speed this is really annoying because the loud noise from the cpu fan with full speed and lasts 5 8 seconds when it is powered on before settling down to normal operating speed. Dell optiplex 9020 low fan speed cpu fan speed is controlled by bios so it depends on how bios was configured for hot. After some test i think optiplex need more fan speed optimization.

My dell optiplex micro 7070 6794 is improperly controlling the processor cooling fan speed. Another optiplex 790 sff is completely silent during booting process. Reboot and press f12. I had report fan speed display issue on aida64 bbs few days ago and the newest beta can display fan speed now.

I know this is not very precise but i don t have a decibel measure device normally the business desktops are nearly noiseless. This is on my 9360 i7 8550u. This will work on most dell optiplex sff small fo. 1 when cpu s temp is between 30 70 86 158 the fan speed have no change at all cpu fan is 11xx rpm system fan is 14xx rpm.
