I have phenom II x4 965 processor. But the issue related with this is when I start my pc it is running hotter and hotter now a days. Few weeks back all things are normal but now it become hot very quickly. The fan which is used to cool it I donít think that it working properly. Because of that fan increase the noise. In the summer time because of proper air ventilation my cpu is sitting at 40C idle. But I think this time a good heat sink will cost me if anything going wrong with my pc. That is for you guys check this.
