For stable and fast operation of the processor, the highest quality cooling is required. Check your fan, and you will find that it is very dusty, there are clumps of dust between the radiator fins that interfere with heat exchange, and if you touch your hand (only carefully) the radiator, then make sure of this, you can get burned, so experts recommend installing cooler new and powerful.
So, let's go and buy a new cooler for the processor, look at the connector type, heat sink material, connection method, size and rotation speed. Typically, the socket types of existing LGA775 motherboards for Intel processors and for AMD processors are Socket AM2 / AM2 +. Choose a good cooler with the ability to connect to all types of connectors. What determines the noise of the cooler? On the speed of rotation, the design of the impeller and the diameter of the fan. There are coolers whose rotational speed is regulated by special sensors on the motherboard that monitor the temperature of the processor, the temperature of the processor rises, the speed increases, and the noise increases accordingly. On new computers, the cooler turns off completely when idle.
The size of the cooler also has an effect on the noise level, a large cooler makes less noise due to a lower RPM, so a small cooler will make more noise. Consider coolers with heat pipes and a copper base, this type of cooler is much quieter than the others, and besides, the processor is cooled by such a cooler much more efficiently. But coolers with heat dissipators, consisting of plates and heat pipes, will allow you to completely overclock your processor without making any noise, your processor with such a cooler will always be cold, it is best to install a cooler of this type. Well, if you want to completely get rid of noise, and your processor is always cool, then a water block will suit you, this is a water cooling system, which is much better than an air one. Powerful system to effectively cool the processor.
