Hi Greatbilal

1 What is the SL number of your processor? You will find the SL number on the BOX or on the silver plate on the processor.

2 What model number is your cooler master heatsink?

3 What motherboard are you using? Exact model number and BIOS version.

4 What Operating system are you using? Any Service Pack installed?

Yes use CPU-Z To find out Family Model Stepping & Revision. That way I will know what CPU you have...

Also you have quite nice FAN in there... has double FAN...but only 3 pings connector. Meaning that there is not speed control on the FAN. Did the previous heat sink that you used have 4 Pings power connector?
