    The fan will not come on at all even after I replaced it. The bottom gets extremely hot and the screen flickers.

Which side of the laptop is getting hot?
if it is the left side, check the bettery. it may need replacement.
if it is the right side, then the HHD need is on its way out, better backup all your files NOW and get a new hard drive.

I have a Dell Inspiron 1525 and recently the fan is showing some noise and its heating up the Lappy


Get a can of compressed air and blow out the vents on the bottom and side of the laptop. The fan could just be out of balance with dust. It it still makes a noise afterward, the fan itself may be going out and need to be replaced.

Laptop Fan noise:

This seems to be a common problem with laptops over a couple of years old. Dust gets trapped in the copper fins and the fan of the CPU heatsink and reduces the efficiency of the cooling, which results in regular power off's by the laptop as it gets over it's upper temperature setting. The fix is relatively easy, just remove the heatsink unit, blow it clean with compressed air, clean the old CPU heatsink paste off with isopropyl alcohol (IPA) and spray a thin film of heatsink paste on the CPU.


If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

A common problem with all laptop is dust. Sounds like you have 5 years worth of dust stuck in there. You should get a can of compressed air and blow though every vent you can! You want to loosen the dust that's in there and possibly try to blow it out and/or get it closest to the vents.

After that you should take a vaacum cleaner and **** out all the dust you can!

Dust inhibits air flow, alot! Its the number 1 killer of old computers.

I was going to say dust is whats causing it but then i relized you have opened your computer. So nevermind that.

The fan speed is controlled by the motherboard. The Pentium 4 processor tells your motherboard how hot it is. so then the motherboard turns up the fan faster. Thats why its louder when the CPU is doing alot and is quieter when its doing nothing. You can try replacing the fan yourself but i would recommend just getting a whole new heatsink.

Sounds like the fan is wearing out, as it heats up the fan needs to spin faster and if the bearings are wearing out it will start getting louder and it will also get hotter because the fan cannot keep up the heat being produced. You can replace the fan, most computer shops will carry replacements, also get a can of compressed air and give the inside of the computer a good cleaning. This will help keep things cooler as well. Also make sure that the air vents on the outside of the case are clear as well.

Is it normal for my laptop to blow hot air from the blower fan and doing some noise every 20-30 seconds?


Not sure which laptop you have but this it is common for this to occur. The noise is the internal cooling fan coming on and this is why you get hot air coming out. In warm conditions some laptops have their fans on all the time.

My dell inspiron laptop runs very hot and is very noisy


The way i see it you have 2 solutions:

Either go to your retailer and get them to dust the laptop and clean it`s fans. (You didn`t specify if it`s still in warranty)

Or solution number 2 would be to buy a special support for laptops.. most have 2 or more fans incorporated so that u get more ventilation. Of course that will not solve the noise problem really..

You also didn't specify how long have u been using your laptop as... with age they of course degrade and there is really no solution for that.

Hi the prob is not with the fan all you need to do is take the cover where the fan is and clean it with a paint brush so all the dust is gone.
