Fans in a computer should not stop when the system is running.

Which fan stops running in your computer?

Hi Hashir, in Dell laptop you have mentioned fan will work if CPU has reached certain temperature. Most common question is why it is on high setting when laptop is idle. Please could explain your problem or what you are truing to achieve?

If laptop is not in heavy use the CPU will be at about 50C, if you start watching film or play a game the CPU will start to work and produce more heat the fan will turn on. When the temperature drops bellow 50C it will stop working.

Hello Hashir,

In addition, check your advanced power plan settings to make sure that you have System cooling policy set to Active for both "On battery" and "Plugged in" like below to see if that may help some.

Sorry I made a mistake. I thought we were working with a Desktop.
Do Laptop fans ever turn off when the laptop is in use.

That seem crazy to me because laptops don't cool all that well when the fans do run.

I bet you all can tell I'm not a laptop user.

On my laptop they turn off and on all the time as needed. As the CPU and GPU gets hotter, the fans will run more often or faster.

 

[Layback Bear]

Well I learned something today. I like that.
Thanks Shawn.

I under stand PWM fans with very in speed with temps I just didn't know off was a option when the laptop is on.

 

[Brink]

Well, when the laptop had been running for a while, the fan pretty much stays on low all the time with an occasional boost of speed as needed.

During image backups, I have a fan aimed at the desktop
And, my laptops each have an external USB-powered notebook cooling assembly [with a giant fan].

 

[Layback Bear]

Ronald if you need a big fan blowing on a desktop you have a case air circulation problem.

I noticed this in your system specs. Why do you have so many anti virus programs on one system at one time?

Antivirus Avast, Avira, CIS - scheduled scans

 

[RolandJS]

Layback bear, yes, the den gets quite stuffy and warm from time to time.
And, only Avast AV real time shields are on, Avira and CIS only run nonoverlapping scheduled scans.

The fans in all of my laptops are set in the BIOS to always on.

Heat issues?

Well for my own laptop:

Cleaning the fan and vents helps. I've even replaced the fan recently. As for what makes it hot - I suppose it depends upon what's actually running.

In the past I've used TThrottle in order to regulate temperature and prevent overheating. It does need to be configured though if you don't want performance issues when running data intensive applications.

Simple settings are - set core temperature and let the program handle the rest.

TThrottle Manual

It would be better to sort out your software issues.

Laptops get hotter and hotter until they melt

Clean it out with compressed air and use a chill mat.

 

[Layback Bear]

Sometimes you need to go inside a laptop to clean it properly.
If you don't feel good about doing such a thing. You need to find a shop that can do that for you.

 

[billmcct]

I have to agree. I've had to take many apart because people tend to set them on beds, couches etc and they will suck up a wad of junk that compressed air want move.
