I received a brand new Inspiron 15R 5521 on Wednesday. It's running Windows 8 and around 30 seconds after starting Windows, the fan starts up and then never stops. I haven't installed any programs and the fan starts without opening any programs or apps. I've gone through the device manager and checked that every device has the latest software as well as installing any Windows updates. It already had the latest bios but I tried re-installing that with no affect. I've ran through the diagnostics from the boot menu and everything passes. The computer is not even warm to the touch when the fan starts and the CPU usage is in single figures. I've also re-installed Windows using the backup image. What could the problem be and how do I go about fixing it?
What's the problem? The fan blowing means the PC thinks it has some reason to keep cool. This could be related to the ambient environment.
The problem is that the laptop is very noisy. I have two older Inspirons at home (one of which is over 6 years old) and they don't behave in the same way. I'm at work now so can't check the temperatures till later but the CPU temp was at least 10 degrees cooler than yours is displaying
"Noisy" is a matter of opinion, so I'll leave that to you. But from experience, my Dell, HP, and Toshiba laptops have all had episodes of high fan usage for (apparently) no reason. Personally I let my PC decide when to cool itself and when not to *shrug*
As far as the noise issue goes, my laptop's very quiet—even with the fan running full speed. When it's idle, if you stick your ear close to the keyboard, you can "just" hear the HDD spinning.
When the fan's running flat out, you can hear it—but it's certainly not intrusive, and oftentimes no louder than the ambient noise around the house during the day. When I'm playing videos or DVDs, I can't even hear it.
We're also running a brand new Toshiba laptop (and an older one) and the DELL's noise is no more or no less than either of those machines.
And as Judah has already said—and I agree—noise is very subjective, and a matter of opinion.
Things you might want to try.
> Run the task manager and check the CPU load - if no program is running it should be less than 5%. If the
the CPU load is much higher let the system run for at least 2 hours to make sure that Windows can download and install all necessary updates ! (this update procedure can keep the CPU quite busy - you can manually initiate the windows updates: open charms/click search/choose settings and type "windows update")
> Try running the system in BIOS mode (usually F2 at powerup) with the mains power supply connected to the laptop and observe the fans behaviour.Then test the system again this time only powered by the battery.
> Under "Power Options" activate temporarily "Power saver" (or whatever is available) to see if it makes any difference
> It is a brandnew system so it is more than right to be suspicious
> to my mind it's unusual for a fan to spin constantly (not very energy efficient if you use your battery)
> Yes - it could be ambient temperature (as Judah pointed out) but it could also be a not properly attached heat sink.......
I just got an Inspiron 17 model 3721 (the brand new one) and I have the same noisy problem with the FAN. BTW I had a lot of laptop in the past, and I never saw any doing such noise like this one. The sound is VERY intrusive and much more louder thant the ambient noise.
And it start just after Windows 8 finish his initial setup and never stoped. So what I will do, for sure
1. Remove Windows 8 crappy OS, and replace it with Windows 7.
2. I will install (Speedfan) and monitor the temp and fan speed.
3. If the laptop will still do that noise, I will return it right back to Dell with a refund. In 2013, such noise from a laptop fan is unacceptable, even for a 600$ laptop.
BTW, everything is up 2 date, including bios. I just now know that at full speed, this fan is very noisy.
Latest BIOS has been updated or Inspiron 3721 on our support site to fix this issue.
Note: Please save any unsaved data as your system will restart automatically after updating the BIOS. Disconnect all the external peripherals like printer, camera, scanner, external hard drive, flash drive etc. Also, the battery should be charged 10% or above.
Please update the BIOS and share the findings.

I am having the same problem with the fan speed with my new Dell Inspiron 5521 i7-3317U, Full HD with installed Ubuntu 12.04. I PURCHASED THIS LAPTOP YESTERDAY. The FAN is too noisy and 1 min after starting the Laptop, the fan start and is not stopping and is not changing the revolutions at all. What should I do, to return back the Laptop. I saw that there is new version of the Bios AO7.
DELL PLEASE HELP!
