Samsung heatsink and fan replacement


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.

Samsung R519 shuts down unexpectadly


Suspect Samsung R519 is dirty inside.

http://www.cnet.com.au/samsung-r519-339300512.htm

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 )

http://forum.notebookreview.com/samsung/117192-samsung-x20-cleaning-cooler-fan.html

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.

If you removed the heatsink you probably need to clean off the thermal paste and reapply before putting the heatsink back on. If the old thermal paste dried out (it generally does), it won't make good contact to remove the heat from the CPU and will over heat and shut off to protect itself.

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 www.cowetacomputerstore.com and we will accomplish the desired outcome. We have worked on this system resolving this very issue.

Overheating


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.
