So I have a Dell Inspiron 3521, I tried to modify the fan speed with different programs, but couldn't, is there a way to do this?

Check the BIOS, sometimes you can from there.

There is a high probability you can not change the fan speed, OEM bios are always locked down on laptops.

Even if you could modify the fan speed, the laptops fan is incapable of pushing enough air to run games.

Desktop PC's are gaming machines. Not laptops.

Well I need it for web browsing, it moves like hell when I try to browse more than 5 pages online or when downloading. I need my laptop to browse the internet fast. And for now my laptop is very annoying. I don't know what to do, I need it for my studies.

Don't fix the symptom, fix the problem. The fan ramping up is a result of heat, if you could lower the fan speed you may end up doing damage.

What temps are you getting?

How long have you had the laptop? Have you cleaned it out at all (physically and software)? Where do you use it? i.e on a desk, tray, bed... etc

The system is running out of memory, and swapping pages out the the hard drive. Find out if you can double the amount of memory in the laptop. If not, replace the hard drive with an SSD.
