Default Is my Laptop overheating

Is my Laptop overheating the fan is staying on high for long exteded periods of time.

I like to browse the web and usalley I have a few sites open that I bounce back and forth from/to.

My LT is Acer aspire I3 CPU 57MOBO probablley over 6 years old.itís cooling fan has been known to clog w/ flith and slow the cooling process.

I donít feel comfortable completely disassembling the LT the PC yes not the LT for the though cleaning process.

What I have been doing is stucking the flith from underneath w/ a wet/dry vacunm cleaner, I also elevate the fan section of LT for good air flow.

Iím concerned why is my LTs fan not cooling the CPU Iím not playing video games are watching videos just 3 open web sites and the LT is stressing will it eventually over heat and turn itself off or will the CPU just burn up?
Thanks for any tips STB

Sounds like it's overheating to me. You can confirm this by running a temperature monitoring tool. The last one I used was called Coretemp but there might be others now that are better.

In my experience it's common for the thermal paste on the heatsink to break down over time and become less effective. Also, dirt in the fan will make things much worse. You can use a can of compressed air to blow out the vents which may help. Many times I have needed to fully disassemble the laptops to remove all the debris and reapply new thermal paste. A computer repair shop can do this for you.

It might not be worth your while taking it to a computer shop bearing in mind that that is an old old machine technologically speaking. Over here a computer shop would charge at least £100 to strip it down clean it out etc. And you can bet your bottom dollar they will find other things wrong with it.

You might pick up a can of compressed air and blow it through the intakes while you're vacuuming the exhausts.

Also, taking apart a computer to dust it is fairly simple It's usually less than 10 screws to pull the bottom off and get access to the intake fan. It doesn't need to be FULLY disassembled.

OK I have a can of compressed air where are the intakes?
Thanks STB

I believe it's the circular vent next to that guy's hand:

https://www.ifixit.com/Guide/Acer+As...lacement/12156

edit: so the picture shows up as a hyper link, but it's the circular vent right next to the exhaust.

Also, it's a good idea to hold the fan still while blowing it out.

Ifixit has a bunch of tear-downs for stuff on this model if you ever need to replace something.

yes the red circle is exhaust, this where I've been vacuuming where are the intakes to blow in compressed air?
thanks STB

the red circle is the intake, the exhaust is on the side of the laptop. even further to the left. blow air into that circled area, and vacuum the exhaust on the side. and try to keep the fan still while you're doing this.

yes I think you are correct the red circle is the intake and I do have the exhaust on the same left side.
maybe a paper clip inserted into fan blades to hold fan in place then blow air inside.

additionally I believe just above the keyboard there is a vent that's the length of the keyboard sometimes I have been know to place papers over the keyboard probally preventing/limiting airflow.
Thanks for the tips will report back w/ results. STB

I blew compressed air then vacuumed also not cover air flow on keyboard. temps at same CPU usage are improved to normal.
I use core temp. previous to clean CT temps where in the yellow overheating area.

Well, the only other thing you can do would be to disassemble the unit and change out the thermal compound for the cpu. Usually the manufacturers use stuff that has a top priority of longevity, not cooling ability. I know you're not comfortable with that, so you might check your local repair shops and ask if they'd be able to do that for you. Even with the new paste though, it'll only bring temps down by like 5 degrees C...

If you do not know check what I do with my own laptop. Every year I go to a technician doing cleaning on my laptop and I have my head quiet. You need to be sure when you open the backside for your moves so that you do not cause a great deal of damage and you can not fix it

I use a high output air compressor for such issues. It seems good enough to clean dust even from inside devices without disassembling.


Dunno what's called in English, but it's a handheld gun look-a-like that exhausts high pressure air. Google images doesn't wanna give a photo for it.
