      Hot Tips for Keeping Your PC Cool in Summer
  Computers hate      summer. That's because it comes with a computer's worst enemy:      heat. Too much heat can cause hard drives to fail prematurely  
   and entire systems to become slower and less stable. A hot day      combined with inadequate or malfunctioning cooling inside a PC      can, in fact,
spell the end of a computer altogether. 
       But there are steps you can take to keep your PC cool enough in      the summertime. By paying attention to how much heat-stress your      PC may be
under, you'll not only extend its lifespan but also      enjoy trouble-free computing during the time you own it. 
  Danger signs 
       How can you tell if your PC is suffering from heat-related      stress? The best way is to take its temperature directly.      Because overheating
is a fairly common concern among system      manufacturers today, many PCs provide temperature readings      either through the BIOS or through system
software. 
       Your computer's BIOS (basic input-output services) is composed      of set up screens that typically can be entered at the time you      reboot your
computer. A keystroke entered at the bootup screen      generally gets you into the BIOS. 
       There, you will often see a screen devoted to temperature      readings from inside your PC. If the BIOS doesn't give you      temperature readings,
chances are good that your system      manufacturer offers a software tool that monitors temperatures      inside of your PC and can sound an alarm when
the heat reaches a      dangerous level. Or you can turn to a free downloadable utility      such as Motherboard Monitor (

       A temperature reading of higher than 60 degrees Celsius on any      internal component is generally a cause for concern, especially      if that temperature
is reached at bootup, when the PC is not      under stress. Occasionally temperatures for a CPU - the main      processor in your computer - will rise
higher than 60 degrees      Celsius, but usually such temperatures should not be the norm.      If they are, your computer will likely slow down, as  
   performance-throttling safeguards kick in, or become unstable.     
  Keeping it cool 
       There are plenty of steps you can take to keep your PC cool      during the summer. First, open up your PC from time to time to      make sure all
internal fans are operating. The onset of hot      weather is a good time to tackle this chore. If you're a bit      nervous about having to pop open the
hood of your computer,      don't worry. Usually removing a few easy-to-find screws or a      popping a simple latch is all you need to do to inspect the
     inside of your computer. Most computer manuals tell you how it's      done. 
       Open the case while your computer is turned off. When the case      is open, turn the computer back on and make sure that all      internal fans spin
up and operate consistently. You should see      two or three internal fans in your average computer - usually      one fan is over the central processor,
while another may be      located atop the graphics card, into which your monitor cable      usually plugs. 
       Second, try to locate your PC in a cool room - or a cool place      within an otherwise warm room. If your room has air      conditioning, place the
computer itself as close to an air      conditioning vent as possible - or somewhere where outside air      circulation is available. 
       The fact is that any personal computer can and will raise      ambient air temperature in a room, so it makes sense to minimize      that effect for
the benefit of the PC as well as for those who      work around it. If you do not have or do not want to use air      conditioning, try to get air circulating
around the computer,      either with an oscillating fan or by placing it near a window      with some air circulation. 
       Third, make a point to remove dust from your PC - especially      around air vents, where balls of dust can accumulate and prevent      proper airflow.
A dusty PC will get hotter internally - and      generate more heat externally - than a PC that's relatively dust      free. Use common sense when removing
dust from the computer.      Turn if off and unplug it first, and try not to directly touch      any sensitive electrical components within. 
       Finally, consider turning your PC off when you're not using it      during particularly hot spells. If you need to keep the PC      itself running,
look for other heat-generating electronic      components that can be powered down while the computer does its      work. Monitors, for instance, can also
generate significant      heat, as can some printers. 
       Thanks to beefed-up graphics cards, supercharged CPUs, and      maxed-out memory, today's high-performance computers generate      more heat than any
personal computers before them. But by paying      proper attention to cooling, you can help to ensure years of      trouble-free service from your PC.
