The PC Doctor's Fix-it-Yourself Guide- P21: A technical director for a UK-based computer company who teaches such courses as Caring for Your PC has developed prescriptions for treating sick PCs. Arguing the benefits of fixing it yourself rather than relying on experts, his mission is to empower users with trouble- shooting and safe repair skills. | CHAPTER 8 Motherboard RAM CPU and BIOS 179 An ideal temperature to aim for is something in the region of 40 C. The higher the temperature the more unstable and prone to crashing your system will be the cooler it runs the fewer crashes you will experience up to a point anyway . FIX-ITYOURSELF HOME REMEDY Heat causes a system to crash because a CPU is made up of millions of transistors. When a transistor gets hot it tends to leak current. If that current leak becomes too great it can result in calculation errors and too many errors will cause a crash. So keep the system cool If you are having trouble keeping the temperature at around 40 C here are some tips that might be of help to you Remove the heat sink and fan and make sure there is a thin film of heat sink compound between it and the CPU. This is easily found at PC outlets and electronics stores. Sometimes you will see thermal pads being sold alongside the thermal grease these may seem more convenient but are not as good as thermal grease. Make sure the heat sink fits the CPU properly. Some brands fit certain CPUs better than others. Check for tilting of the heat sink or obstruction by other components on the board. Make sure the case is well ventilated. There is no point having a good heat sink and fan if there is nowhere for the heat to go. Ideally you should have at least two fans in your case through-putting air one blowing inward normally in the front of the case and one blowing out. Get yourself a better heat sink and fan assembly. There are many specially designed for use in overclocked systems that are far superior to the heat sink and fan assemblies that come with most PCs. Keep heat sinks clean and dust free. Clean them regularly with compressed air. Make sure the PC case is in a well-ventilated area not too confined by books or shelves and that it s not positioned in a hot place like near a heater or stove . An inexpensive way to find out if more system cooling will help your system is to go to an .
