Re: Allow laptop fan to stay on

Have you tried software such as Speedfan? That allows you to control various aspects of your CPU fan. However CPU fan control software has to be supported by the system's MOB and usually does not work on most laptops. Worth a try but don't be surprised if you have no success. Have you tried updating the BIOS as sometimes an upgrade has better fan control.

For what it's worth I have the 5575. And there is a BIOS update available dated a few days ago which offers enhanced BIOS features. My fan comes on intermittently at some strange times like startup when the CPU is obviously not stressed or overheating. I assume that is just a power up fan test. Have never had the system shutdown though from heat such as a long session playing WoW.

If you update the BIOS let me know how it goes and if any new features are added.

Re: Allow laptop fan to stay on

Thank you for your message. I am afraid, there is no applications or options available from Dell for fan control. There are 3rd party applications available, they have not been tested by Dell & do not recommend them.


What is the BIOS version installed?  What is the Temperature status in BIOS?  Does the system heat up & shut down when using applications?
