Why does your computer over heat?

Answer 1

Could be several things, if it is a desktop be sure that it has enough space around the case to provide for good airflow, a couple of inches on the back and one side is usually enough. Check your vents for dust, if you see dust and other gunk get some compressed air in a can and blow it out. Open up your case and check for dust built up around the fan and heat sink (this looks like a series of metal fins) blow out with compressed air. Listen to your computer and see if the exhaust fans are kicking on. You normally have to wait a little while for them to start running, if they dont kick on replace them!

If you are using a laptop be sure it is sitting on a hard surface if you leave resting on your bed or couch it will resrict airflow to the fans, casuing it to overheat, also blow out vents with compressed air. Dont try and take it apart unless you know what you doing though!

If your computer has been overheating often your processor could have sustained damage. If you fix the overheating issue you may find that your p.c. still acts wacky. You might have to replace your processor, or even other componets depending on how hot it actually got!!

Answer 2

Something with energy consumption. For laptops its even hotter since its a more rechagable battery and something that has to with a laptop needing to be more portable. Yeah my laptop gets REALLY HOT so i use a fan i got from staples for $15 it works. I also have a Super Computer with a 8600GT card that i have three fans inside the computer so its pretty cool. I know someone is going to say this is way to confusing!

It in short terms if your copmuter gets to hot use a fan you can get them at Staples or at Best Buy. Some where in you computers batter setting there may be something called Power Saver Mode try using that it lowers the temp by a little. Theres probably a Advanced setting where you can contol the temp of your laptop/computer since all computers have a built-in fan. Unless you had a severe problem like my Gateway from 2002 its fan and hard drive disk blew off and and hit each other causing a little fire. THAT's WHY FANS ARE SO IMPORTANT! They keep things from braking/melting :)

Answer 3

Actually computers do not use heat, it is very harmful to a computer if there is heat in the computer case. This is the main reason there are so many fans in the case and why they blow air out not suck air in.

Answer 4

Computers are basically built up on circuits, and circuits are basically elaborate versions of a piece of wire. If you run electricity through a wire (like you do with a incandescent light bulb), it will tend to heat up. This is because of a property called electrical resistance (equivalent to "friction" in electricity). The more resistance a piece of conductor (say, a metal wire or a computer chip), the more work the electricity has to work through through it and thus it heats up.

Answer 5

In the CPU alone you have millions of transistors changing state millions of times every second. If you think that's hot, I can remember vacuum tubes.

Answer 6

Just all the processing it takes in the computer. If you have a good working cooler in your computer it should be cool. But It is all the working cables and processers inside the computer.

Answer 7

fan is blocked

Answer 8

Battery warms.
