Instructions on how to remove the cooling fan of the standard CPU LGA775

 The cooling fan is a part that helps keep the CPU's temperature stable when the computer is operating. After a period of use, if this part is damaged and does not work well, it will cause the CPU to overheat, resulting in the computer slow down or stop working (hanging). The fan must be removed to repair or replace the cooling fan. This article will show you how to remove the cooling fan of the LGA775 standard CPU.
