Mitac 8640 Laptop Processor Cooling Fan

I have a Mitac 8640 Laptop. The fan has been making a lot of noise for a few months. Now it runs for about 10 minutes then suddenly shuts down. I reckon the fan is shot and the processor is overheating. I'm not even sure how to get to the fan though.

How do I:
Remove the old fan.
Order a replacement.
Fit the replacement.

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.

My laptop fan had been making noise for a few months and now just stoped working!!


Hello:
Generally, all laptops cooling fan start for a second just after power on and you may notice noises. These noises, comming from the fan, are because it is dirty. So, it may be jammed by dust excess. If this is the case, you need to take apart it and inspect the fan while booting the machine. Removing the keyboard would let you see the fan and clean it. Try to move the vane with your finger to make sure if it is not obstructed. Maybe, you need to take the fan out and oil its axle. Besides you can check if its power cord is attached correctly. It is not recommended to operate the laptop with this malfunctioning fan.

I hope this helps you. Thanks

Fan noise after a few minutes running.


Fans are typically a little noisey. If it's exceptionally loud or continues for a long time it may indicate the fan is no providing the proper cooling. Purchase a laptop cooling pad to place under the laptop while your useing it and make sure nothing is interfering with the airflow around the unit.

Hi, my compaq CQ50-115NR used to make great fan noise...now, nothing and it gets hotter and hotter...what should I do?


Have the fan replaced.

The 'great fan noise' you heard was the fan's bearings.
The looser the fan bearings became, the more the fan tilted, allowing the center hub of the fan to rub against the bearing base.

A laptop has a poor cooling system. All of the hardware components, are crammed into one tiny box. Air is the only cooling medium to keep these components cool.

The Processor, and the graphics chip are the two components that give off the most heat.
When a Processor becomes too hot, it turns off.
(BIOS turns it off)
This is a Fail Safe feature built-in, to keep the processor from burning up.

I would advise not using the laptop until this has been corrected.
Is the laptop still under warranty?

My Sony Vaio laptop makes a lot of noise mostly it seems from the fan. This is intermittent but seems to happen when I have had the laptop on for a long time. What might be causing this and is this serious...


Your processor is probably getting too hot. When it gets hot, the fan speed will increase. You will heed to have the processor heat sink checked, cleaned, and new thermal paste applied to it. You will also need to clean your cooling fans if they are dirty.

The fan is making a lot of noise. this has


Is the laptop dirty inside?

If it hasn't been cleaned out regularly, with a can of compressed air for computers, more than likely it is.

Laptops typically have a poor cooling design. For one, everything is crammed into a tiny box.
For two, there is a small duct, (Air Intake Duct), that draws air in.
For three, laptops typically just have 1 small fan.
For four, the Air Intake Duct is located on the bottom of a laptop, or on the side.
This is an excellent (?) area to draw foreign debris in. Another word for foreign debris, would be CRUD.

Hair, Food Crumbs, Lint, Dirt, Dust, and so on.

A laptop's cooling systems primary function is to keep the Processor at a certain temperature. If the processor becomes too HOT, it turns off. (BIOS turns it off)
NO Processor, No computer!

1.The excessive fan noise can be that the fan is spinning at top rate, trying to keep the processor cool. It's having a hard time doing that, because the fan cannot draw enough air in. (Clogged Cooling System with Crud)

2.The excessive fan noise could be that the fan's bearings are bad.

3.The excessive fan noise could be that the Processor is running at 100 percent, (100%), and the fan is running at full speed, in order to keep the processor cool.
Perhaps caused by a virus, or some sort of anti-virus program, or running more than one virus program. (Installed a new anti-virus program lately?)

Noisy fan


You need to replace the fan. Measure the fan you have now and buy one the same diameter. Then remove the old fan and put in the new fan.

Laptop switched off while i was working on it


After the notebook shuts down do not turn it back on for 15 minutes and then test it again. Will the notebook work longer if you let it cool down for a while? Isn’t it hot if you touch the bottom? Can you hear the fan running?
Most likely you experience a laptop overheating problem and it would be fixed by cleaning the cooling module – the heat sink and the fan. The notebook processor produces a lot of heat when the notebook is turned on. The cooling module helps to keep the CPU cool when the laptop is working. The cooling module includes two parts: the heat sink and the cooling fan. The heat sink is attached to the CPU and helps to conduct the heat from the processor to the radiator. The cooling fan blows on the radiator and helps to disperse the heat produced by the CPU. The laptop will overheat if the heat sink radiator is clogged with lint and dust or if the cooling fan stopped spinning.
If your laptop shuts down after some time without any reason and warning, check if the cooling fan spins. Usually it makes some noise and you can hear it. If the fan works fine, then check if the heatsink is clogged. In some cases you can clean the heat sink with compressed air, just blow inside the fan openings on the laptop bottom. If the heatsink is completely clogged, then it is necessary to remove the heatsink for cleaning.

Fan Noise on Dell Dimension 8100


All computer fans have a general design.  The name in front of "fan" really refers to the designation.  You'll see case fan, processor fan, CPU fan, cooling fan, etc.  In the case of CPU/Processor fan, some are sold with heatsinks (the metal block sitting on top of your CPU).

The first thing you want to do is make sure the fan is clean.  Chances are dust buildup is causing the excess noise.

If that's not the case and you're looking to replace the fan, then you first need to find out the size of the fan. General sizes(diameter X width in mm) are listed on this page:

http://www.svc.com/case-fans.html

Generally, you're looking for something that will match the size of what you're replacing & push enough air at a reasonable noise level to cool the heatsink/CPU.  You want to stay in the area of 30dBA max for noise.  You also want to see if it has a 3-pin or 4-pin connection.

For example, if you have an 80mm fan, I would suggest something like this:

http://www.svc.com/saf-b82-19.html

It's pretty quiet with good airflow.  Also, it has a 3-pin connection, but includes an adapter for a 4-pin connection.
