Summary0001720: Sets Dell Optiplex fan speed to be very high, cannot change
DescriptionHello - I don't know if this is a bug or not but I couldn't find how else to get support. I have a Dell Optiplex 755 (small form factor PC) with a dual core Intel CPU. It has Vista Business SP2 and 1 GB of RAM. Anyway when I launched SpeedFan originally it only showed my CPU core temperatures which were 21 and 22 degrees C as well as my HDD temp. It did not show voltages or fan speeds or anything else. I went into the configuration and selected to enable Dell laptop support (since this is a small form PC it has many laptop parts). When I closed and re-opened the application the system fan(s) came on full blast. Now I could see the fan speeds (but not voltages) on the main page and they were both around 1800 RPM. the fan is on the front of the PC as an intake fan and I could feel it from where I was sitting! It was very loud. I have never heard them that loud before; it sounded like an airplane. CPU core temps dropped to 17 and 18 C within a minute. I closed Speed Fan, opened it and tried disabling Dell support, playing with what I thought were the fan speed controls but it made no difference. I had to reboot the PC to get the fans to slow down back to normal. I have Windows Steady State so rebooting also erased the Speed Fan program completely off the computer. Now I am afraid to reinstall it but dell suppport wants me to monitor my computer temp. Help?
Steps To Reproduce- went into configuration
- selected to enable Dell laptop support
- closed program
- re-opened program
- now cannot get fans to tune down. Had to uninstall program.
Additional InformationI don't know what model my motherboard is but here is a link to the manual.
