We'll talk about remedies in a bit, but first let 's talk about how laptops and netbooks are cooled computers and why they can overheat.
All computers generate heat . The main source of heat in laptops and desktops are the processor and graphics chips . This heat must be dissipated or these devices will live a very short life , ranging from several minutes to several hours.
How do you manage this heat ? A device called a heat sink is attached directly to the chips . A fan inside the case while blowing hot air through the radiator and the outside of the housing . In an office, there is plenty of room for large heatsinks and more fans . In some offices cooled liquid systems are used. Although the space available within a computer is advantageous for the cooling , it is not the case for portable computers. Due to the space , cooling and heat removal is lowered a challenge .
How a laptop is cooled ? To cool the CPU and graphics chips inside a laptop computer , a special heat sink is used . This heater typically uses heatpipe technology to move heat from the device to a heater that has a fan attached to blow air through its fins on the outside. This is where hot air can be felt coming out of your laptop. Yes, a radiator , a well as a car is inside your laptop! If the space between the fins is blocked, the air flow is limited , causing the accumulation of heat on the processor and the graphics chips . This is what happens over time the majority of laptops that overheat. So how can you tell if your laptop is overheating ?
Three warning signs your laptop is overheating.

When a laptop is first turned on, it often happens that the fan runs at full speed until the operating system begins loading . After logon the fan should slow down. If the fan speed again shortly after the laptop has been activated, your laptop cooling may be compromised.
3) Performance - Is your laptop slow or even freeze after a short period of use? The processor seems to run about 90 % capacity or more after its been for a while ?

Canned air can be used to maintain the cooling system and in most cases to avoid obstruction to accumulate. The compressed air spray in the vent once every two weeks to thirty days will be sufficient. However, once a shoe built within the ventilation chamber , the compressed air will not work. In fact, it can dislodge the plug of lint and block the fan.
2) USB coolers and coolers - If your laptop is overheating a clogged cooling system . Then an external cooler will do little to help . These devices , however, are good for one thing.
