Dell Optiplex Cpu Fan Control

I know this is not very precise but i don t have a decibel measure device normally the business desktops are nearly noiseless. I had report fan speed display issue on aida64 bbs few days ago and the newest beta can display fan speed now. 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 cpu fan control.

I bought a brand new dell optiplex 790 with ssd 8gb ram and i7. Go to utilities partition and run the fan diagnostics. Dell optiplex 9020 low fan speed cpu fan speed is controlled by bios so it depends on how bios was configured for hot. In aida64 stability test.

Tried running cinebench after disabling the ec fan control. However it seems that while its disabled the cpu frequency refuses to go over 1 39ghz. 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. The system is brilliant so far.

Optiplex 990 cpu fan never goes below 2000rpm there are no dell optiplex systems that allow bios fan speed control. 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. Your dell pc may contain several fans to keep the internal components cool. Tried the alt mode next and it then runs full cpu clocks.

This will work on most dell optiplex sff small fo. This is on my 9360 i7 8550u. Another optiplex 790 sff is completely silent during booting process. The only thing is the noise of the cpu fan with is very noisy for a business device such this.

In this video i walk you through taking apart and turning the cpu fan around so your computer stays cooler. Lint and dust accumulation prevents air from flowing around the cooling fins and causes the fan to work harder. My dell optiplex micro 7070 6794 is improperly controlling the processor cooling fan speed. 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.

Temps go to near 100 but then cools by throttling the cpu. Under cpu load the fan speed increases with a long delay. Reboot and press f12. After some test i think optiplex need more fan speed optimization.
