6 tips to reduce the noise your computer

1. Make sure the CPU fan is working properly. Replacing old fans can reduce the noise considerably. If any wires are dangling on top of the fans, tie them up so that they don’t touch the fan.
2. If the CPU casing is open the noise level is more. By screwing it up the noise can be deafened. The casing should be placed flat on the surface to reduce noise.
3. Remove any dust that is accumulated inside the CPU. Keeping the computer clean will reduce the chances of wear and tear. A vacuum cleaner can be used to clean inside the computer using a special attachment at the end.
4. If you are using a mouse with a rolling ball, switch to an optical mouse. The sound made by the rolling ball can be eliminated. The noise made by a CRT(Cathode ray tube) monitor can be overcome by using a better technology.
5. The speed of the CPU fan can be controlled in some of the newer machines, check if you have that facility and install fan speed control software.
   
6. Keep any other electronic devices like mobile phone, television etc. away from the computer as they can cause interference.
