Default Weird Laptop Fan, CPU

Hello TF members long time no see.
Okay this problem has been happening in my laptop for a while. Its fan almost never shuts up except for very rare occasions. Even when the laptop is idle, it still produces a sound. Sometimes it even screams on running not very demanding apps.
Also, in Safe Mode, this fan doesn't shut up! And when I put my hand next to the air vent, there's actually hot air coming out.
Also when I try to turn off the PC from safe mode, it gets stuck at "windows is shutting down" message and I have to turn it off manually from power button.
The sound isn't very bothering and the temps aren't too high, temp at idle is 34C for core 1 and 36C for core 2. It's just I feel this fan is gonna be fried!
One more problem (hehe) in CPU-Z, it shows that this laptop doesn't go below 1899 MHz ( full speed )
My laptop is very unknown, Daewoo DB-4108s
Specs :
T3100 Dual Core CPU @ 1.9 GHz
1 GB 667 MHz DDR2 Ram running at 768 MB only because 256 MB are reserved for Sis672 integrated GFX
Sis672 integrated GFX 256 MB
Thanks in advance.

Did you clean the fan out, at all? That may be why it's screaming so loud. Also, the ball bearing could be off.

Cleaning the fan? I don't see any dust in the air vents. It's not very loud actually unless I'm playing a game.. It's just I'm afraid that because the fan is working a lot it might be fried thus frying the CPU making the laptop useless.

During gaming, it should blow loud. Your temps go up as you play.

Yep I know of course. But, even in idle ( and according to Realtemp the load doesn't exceed 2% ) the laptop fan keeps spinning in a heard voice and shuts up very rarely. I'm afraid this might damage the CPU fan. I'm thinking of getting a laptop cooler if this will help.

It is a problem with the BIOS, that controlls the fan speed, or the fan itself that is bad.

My Bios is very basic with no such options.
Are fans replaceable? Or if this one goes bad then my laptop is gone? Should I get a Laptop Cooler?
And if you know the answers to my other questions, please tell me
Thanks so far for the help.
EDIT : I just noticed the laptop whistles! it's producing a weird whistling sound! A Sound similar to that of the sound of your ear when you feel your ear is whistling.

get a new fan. Open the thing up, get at the fan, measure its size, and get one off eBay or something.

So it's 100% the fan? I just don't want to buy a new fan atm without it being important as I'm saving every $ currently for a new fan, heatsink, PSU and possibly a GPU for my PC

The fan could cost just $5. Buy one, or deal with the sound. Those are your choices.
