Thank you for replies
My system is new and came with stock AMD HSF with the fan producing much noise at RPM speed over 5000. My temperature on the core is not to exceed 62C and under normal use it stays 41C to 44C and in very hard gaming use it has not passed 53C.
I had thought to reduce the noise of HSF by trying to stack fan to cool down the area of the chip thinking it would then not go as high. I have assumed speed increase as heat increase inside of area near the CPU chip.
The chip system is under warranty with the rest of the computer and changing HSF to another would void the terms so I thought leaving fan in place only adding to the cooling.
Thank you for helping
