This is a total teardown of the computer! Man, I'd hate to be you. Please make sure the screws that hold the fan down are secure. You don't want to burn out the processor. Is it a laptop or desktop. Need to know.

If the heat is excessive and/or shutting down because of heat issues, your fans and heatsinks might be dusty enough that they can\'t get the heat away fast enough. At the least, you should remove (or have removed at the repair shop if you cannot disassemble the laptop properly and/or completely) the cpu and/or gpu fans and heatsinks and clean them out with a can of compressed air. When they are removed, you should replace the cpu and gpu heatsink paste (non-conductive thermal compound) so that they can efficiently dissapate the heat they produce to the heatsinks. Also check your cooling fans for free spinning. Give the fan a clean, then try giving it a spin with your finger, it should continue to spin for a second or 2, the longer the better. If it stops spinning immediately, the fan might have to be replaced too.
If it runs, but gets hot ....
The following advice should be given to all laptop owners : the little rubber feet are important and should be replaced with something at least twice as high. Put your laptop on a flat surface, like a table, and look under the laptop. The little rubber feet give it airspace under the laptop, where most (but not all) laptops have the fresh air intake for the fans. If you cant see through under it, it wont get the cooler airflow it needs. A laptop cooler works best, but if you dont have a laptop cooler, you can use 4 plastic bottle caps (or similar) under the 4 corners to keep it up higher. And dont ever run the laptop sitting on a couch, chair, blanket, lap !! or any non flat hard surface, because the little feet wont keep it up high enough and the fan(s) will suck dust, lint, hair ... into the fans and plug up the heatsink(s)

Samsung R519 shuts down unexpectadly

Suspect Samsung R519 is dirty inside.

The cooling system for the Samsung R519 is the Cooling Tube, Heatsink, and Fan Assembly.

The Fan Assembly consists of a Fan, and surrounding cage. (Shroud)

The Heatsink is a thin piece of metal, that has Tall, Thin, fins protruding from it.

The fan's blades, center hub, and surrounding cage may become clogged with 'Gunk'
{'Gunk' = Dirt, dust, hair, food crumbs, lint, etc}

The fins of the Heatsink may become clogged. In-between the fins, and all over the fins.

{ The Heatsink absorbs heat. It then radiates the heat way through the Tall, Thin, fins }

When a Processor overheats, (Surpasses it's Thermal Limit), it turns off.
(BIOS turns it off)
This is a fail safe feature built in. Keeps the Processor from burning up.

With the cooling system being clogged, the Processor overheats.

Solution is to clean the laptop THOROUGHLY. I don't believe at this time a can of compressed air for computers, blo-wing air from the outside, will help.

It will just push the 'Gunk' in tighter.

The laptop needs to be disassembled, and thoroughly cleaned out.
It may, or may not need new Thermal Paste for the Processor, and graphics chipset.

(If the laptop has been cleaned recently, and has this problem, it's because the 'tech' probably didn't replace the Thermal Paste.
Thermal Paste will dry up over time, and lose it's thermal conductivity properties )

Do you wish to attempt this cleaning procedure yourself?
If so post back in a Comment, and prepare for a LOT of reading.

(The R520 is VERY similar )

The above is for a Samsung X20. Posted, because I would like you to look at the last photo on the page. Here you see an average finned Heatsink, and the 'Gunk' it can collect.

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 laptop gets shutdown regularly when i using

The laptop will shut down if the CPU overheats, this is known as thermal shutdow. If this is not fixed, eventually the CPU will fail.
This problem is caused by either a faulty CPU fan or the CPU fan and heatsink are clogged with dust.
Check the CPU fan, if it doesn't spin freely, then replace the fan.
If the fan and heatsink assembly is clogged with dust, then remove the dust and blow the dust off the heatsink with a can of compressed air.

I have the same problem for Sony VGN-S460 heatsink fan problem

I trust that you have purchased the entire fan assembly as they are inseparable from the heatsink. You must disassemble the entire laptop in order to remove the fan assembly. they are two screws that are below the motherboard that must be remove in order for the fan assembly to come apart.
If you cannot achieve this yourself, or lack confidence in your ability to rebuild the unit after, you can send the unit to us at and we will accomplish the desired outcome. We have worked on this system resolving this very issue.

I need to replace the cooling fan and heatsink on my Gateway ML6720. I'm having trouble finding the part. If I can find it, can you tell me how to replace it?

The best thing you can do is replace the fan itself with a like kind of shape and size. I usually do this by going to a computer store with the old fan and matching it up with the ones they have in stock, or measure the size in milimeters and buy one on line. The fan is held on by 4 screws and it is much easier than trying to remove the heat-sink and take the chance of damaging the motherboard. You can just screw the new fan to the old heat-sink and you are done, plug it in and insure the fan is blowing in the right direction and you are done. Good Luck, RAC

yes its probably the fan but it could also be the screen brightness. replacing the fan and turning down the brightness will cool the laptop. but i agree try a new fan first.
