Cleaning the fan and heat sink

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.

My HP Pavilion dv6 WW146AV runs hot!

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.

My dell computer keeps shutting down every 5 min or so. I cleaned th fan and still the problem happens. I bought this almost 4 and a half years ago.

You may have cleaned the fan but have you cleaned the metal cooler (heat sink) under the fan? Its better to remove the fan from the heat sink and hoover it out, then refit the clean fan. Also hoover out the power supply vents too. Also make sure any case vents are clear too. If you think overheating is the problem then run the pc with the case open and if it runs ok then overheating is the problem.

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 compaq presario c 700 laptop keys sticks and runs hot, also runs very slow

sticking keys well! theres only one thing you can do about that is take the keyboard apart and wash the parts in a weak solution of detergent and clean the rest with a damp cloth--someone must have spilt a cup of coffee over it at some stage.
if it runs hot replace the fan,clean the aluminum heat sink of dust ,,hot aint such a big deal as long as the plastic isnt melting
Slow--try anotherOS

My hp pavilion dv4000 is running hot. takes


Thank you for your query

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

Acer laptop gets very hot inside fan is running but still hot ?

Your heat sink vents may be jammed up with fluff and other debris.

If you're not comfortable removing the bottom pannel and using some canned air to clean out the heat sink fins, I would take it into a repair depot and have the techs there apply a new application of heat sink compound and clean it out for you.

Notebook fan is not running and unit is getting hot

the fan vanes are clogged, this may happen if you have pets or live in a humid region.
take the unit apart and remove the heat sink from the laptop, get some arctic ice silicone from a computer store and apply an amount equal to that of a piece of rice to the processor (after first cleaning of the residue on the heat sink), clean the cooling vanes out and replace the heat sink, put the unit back together and the unit should not overheat again.
The silicone will take a while to solidify to the optimum.

Laptop running hot - Fan cycling on and off every 10-20 seconds

My guess is that CPU fan, it there is one, is not working properly and your computer is heating up. Is it turning off, too, occasionally after a period of time? Suggest a new CPU fan.
