Every once in a while i use my air compressor to blow out all the fans. i guess if you dont have access to a compressor you can always get one of those cans of compressed air at any electronics store or hardware store im sure.

Laptop crashed


Really need more information, but my guess is dirty fan. If fan is blocked by dust, it may make noise and may run at high speed all the time because the CPU is overheating. If CPU gets hot enough, the laptop will shut itself down without warning. If dust is the problem, get some canned air. Before blowing into the air vents, try to spot where the CPU fan is and gently insert a toothpick to block the fan and prevent it from turning. A long blast of compressed air can spin the fan too fast and burn out its delicate bearings. Blow air from underneath and also from the side vent until air blows clear. In some bad cases of dust, the bottom or top cover must be removed to get it all out.

Laptop fan making noise


You need to clean the fan blades to stop it. Due to blades getting covered by dirt your fan cannot throw out the heat. thus it runs more fast and makes noise. also the heat sink gets covered by dirt unable to radiate heat . thus your laptop gets heated fast. clean those dirt and the problem will be solved. thanks.

This morning my sony vaio nw20 serirs started making a kind of screeching noise from the fan area, it has not been dropped or damaged in anyway and stated with no warning


Laptop fans and heat-sinks collect dust in no time.
You need to maintain this clean, otherwise your laptop will over-heat.

Try to run compressed air in the fan and other laptop vents to clean any dust.

If the fan still does the noise, this mean that it will fail in the near future.
If the fan stop turning completely you have to turn off your laptop and leave it off until you replace the fan.
Don't use your laptop with no fan, if you do the processor will be permanently damaged.

Toshiba Satellite L500D is shutting down by itself OVERHEATING Clean the fan with compress Air ....> NO GO Need help Please or Any other Suggestion


Disassemble the laptop and remove the heatsink.
Remove all the dried up heatsink goo that's on the heatsink and processor.
Squeeze a small amount of QuickSilver heatsink compound onto the middle of the processor top.
Place the heatsink on the processor and move it in a couple small circles before locking the processor heatsink back in place.
Clean the air vents and cooling fins well while the unit is open.
This should fix any overheating issues you are having (assuming the fan is OK)
If the fan isn't running, replace it.

My fan is making so much noise but stops sometimes when i shake the system


you will have to dismantle the laptop remove the processor fan and clean the surface of the processor and the fan and apply a thin layer of heat sink compound and fix them tightly to the socket when the heat sink compound gets dried up the heat dissipation of the processor changes the thermostat in the processor fan send to increase the speed of the fan as the processor heat rises to cool the processor

My nv7802 overheats and shuts off,fan is running but the heat sink gets very hot


The fan may be running too slow (faulty bearing) or the fan and heat sink assembly may be clogged with dust.
Check the CPU fan to see if it spinsfreely, if not replace the fan. If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.

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.

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.
