Customer came to us with his machine getting very hot and cutting off.
Reason being over time laptops pull in quite a lot of dust – and it gets trapped around the heatsinks and fan.
Also the thermal paste laptop manufactures tend to use is very cheap – as a result its not too effective long term and dries out quickly. We clean out this old paste and reapply Arctic Cooling’s MX-4 which is high performance thermal compound suitable for overclocking which provides a much better conductive channel to the heatsink.
Afterwards we stress tested the laptop to ensure the machine operates at reasonable temps.
You should consider to clean your Laptop or PC at least once a year. If you don’t, it may cause you problems like overheating, blue screens, slowing down and eventually dying.
When your laptop gets dirty and dusty inside, the dust that collects forms a “blanket” over the exhaust grills, stopping the fan from pulling in cold air and pushing out the hot air coming from the processor.
This is the result – see pictures below for before / after shots.
Dirty dusty overheating laptop.
This laptop came in with complaints of overheating and random shutting down while in use.
It seemed like the fan was not spinning.
We took the machine apart (yes we make it sound easy), and found the fan had become clogged up with dust, and as a result the fan motor had burnt out.
Also, the dust had got into other parts of the laptop, and was blocking the vents where air would normally escape.
We replaced the faulty laptop fan, cleaned all the dust out and replaced the worn thermal paste with new high quality Arctic MX4.
Result: cooler and happier laptop!
Before – dusty and hot and noisy…
Process = disassembly, cleaning the dust off, removing old cooling paste, applying new cooling paste, assembling back together
After – nice and clean and cool and quiet ;)
It’s very important that your laptop is able to extract heat from away from the processor, hard drive, ram and the rest of the motherboard.
As you can see from the pictures, the fan and heatsink are clogged up with dust, turning it into a blanket (and keeping in the heat).
Imagine this heat build up over time, re-circulating inside the laptop, and you have the perfect recipe for a disaster.
At Laptop Doctor, we recommend get your laptop deep cleaned at least once a year (if you want your laptop to live longer).
