If the processor temperature increases, it noticeably loses its productivity. After exceeding of some critical temperature, a processor “burns” – this is the main cause of its failure.
The processor overheating is the main cause impeding its overclocking and normal productivity. If you buy a new processor or computer, always ensure if there is a good fan. You should not skimp on this.
A common fan consists of a radiator extracting the heat and a propeller moving the hot air. So, the better radiator and the more ribs it has, the better heat is transferring from the processor. And the faster a propeller rotates, the better this heat is extracted. Nowadays two-propeller systems are widely spread, but such fans are very noisy and you may buy them only if your system unit will be kept rather far from users. You can also find the cooling water systems but they are rather expensive.
No air layers should be between the processor and fan – a good thermal insulator significantly influences the heat transfer from a processor. To extract the air and to improve the heat-exchange, use special silicone thermal grease. Spread it with thin layer between the fan radiator and a processor.
A size of your system unit, the power of a fan and additional sources of ventilation also significantly influence the processor’s temperature.
