My computer runs very hot and the fan runs constantly, making everything run verrrrrrry slow. i was told to clean the fan and heat sink........... my issue is that i need to know how to do so.
i know how to open my computer where i can see the fan and what not, but i need to know the next steps. of course sony tells you to keep the fan and heat sink clean, yet they do not have instructions on how to clean it.
i would like someone to walk me through the steps of getting to the fan and heat sink and the whole process of cleaning it, pictures would be great. otherwise i would like to know where i could possibly buy a manual that will tell me all of this. i would appreciate any help!
thank you!! :)

Re: cleaning the fan and heat sink
I would first check for any trojans, virus's and spyware, and any programmes running at start up you don't need, as that can cause overworking of the processor, then instead of stripping down the notebook, which i don't recommend,look around any vented area of your notebook and hoover out the vents gently, this will remove any dust blokages.
Give your system a good clean out with this excellent free tool called ccleaner and you can also dissable any startup programmes you dont want with the programme also.
Download it here, fre and free updates and spyware free, click link and then on the right of link click download latest version.

It's possible that either the chip it's cooling is running hot. The heat sink inside may be covered with dust preventing the chip from being cooled. It also might be dust on the fins of the fan itself causing the extra noise.
You should have it checked out and cleaned to prevent possible damage and fan failure.
- Stop Overclocking your CPU.
- Make sure your Heat Sink is placed properly above the processor.
- Clean the Processor fan, Heat Sink and other peripherals.
- Use High Speed fans.
- Use CPU Heat Sink Paste in the processor.
- Fix OS registry with reliable program like I always use Reginout.
- Shut down your computer at least two hour a day.
In order to address this the unit must be taken apart, remove fan and clean with compressed air, next remove the heat sink, four spring loaded screws turn one "small amount" go diaganal do the same and the next two until removed from the processor ic, blow out any dirt, next remove old silicon grease with rubbing alcohol, apply fresh thermal grease to the ic and heat sink "small amount" and assemble.This will solve most issues.
The CPU Heat sink (the big metal block with a fan) may not be making good contact with the CPU surface area.
Thermal compound may have not been applied between the CPU surface area and heat sink
The heat sink and fan are not sufficient enough to cool your CPU
Dust buildup is not allowing proper circulation of cooling air
If this system is not a name brand and covered by warranty then I would remove the heat sink (carefully) and verify that the mounting bracket is not broken or loose. I would check that ample thermal compound is applied, and if not use rubbing alcohol to remove all compound from the heat sink and CPU and purchase a tube of compound to apply yourself. I would also thoroughly clean the heat sink with compressed air.
If the heat issue continues then you will want to consider upgrading to a more powerful cooling solution.
The CPU fan should run constantly but in some systems will run between 50% and 100% speeds assuming a variable temperature control is applied to the system via motherboard or third party installation.
-try adding additional fan in the casing
-in adding fan make sure that you have a blower fan and a exhaust fan where in air can get in and out inside the case.
-add thermal paste/grease between the processor and the heat sink. it is often used to aid the processor's thermal or heat transfer via heat sink. -you can also add blower fan in the chipset of the motherboard-you can also add heatspreader in the memory.-check the power supply if you are getting enough power -having too much power may result in over heating and may damage the devices-having less power may result slow system and bad performance.
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.
Have you replaced the heat sink thermal paste?
Also the fan blades may look clean, but have you removed the fan and checked the outlet grill that the fan blows through, it gets clogged with fluff, dust and hair etc.
With laptops there is hot and there is hot, the normal type of hot is due to general use and should be expected, especially as people who put on their laps and dont allow the heat to escape
However there is a different hot which is very hot to the feel and occasionally there is a burning smell coming from it. if you are experiencing this problem then please do the following
1) Switch on laptop
2) Press F2, F12 or ec key to enter BIOS setup
3) Once in bios look thorugh the menu'suntil you come up with a cpu temp option
4) Leave the laptop runing on this if the temp increases very wuickly and goes above approx 50 degrees (celsius) then your CPU is overheating and is probably the heatsink that needs replacing
If it is the heatsink, i would not recommend that you replace yourself as you will need to go down to motherboard level
if it doesnt then it is normal operation for your laptop
If this has been useful please leave postive feedback/vote/testimonial - Thank You Again
How many HDDs/internal devices are you running off *********** board? If you have an AMD processor, they tend to run hot too. If your computer is running agonizingly slow or shutting down by itself, I would suggest you do the following:
Take your heat sink off your CPU and clean off the heat sink paste and re-applying. If you haven't done this before, you only need to put it on in a VERY light film so you can partly see through it. Applying too much can cause over heating.
