Here's a cheap and easy way to make your CPU temperatures lower.

 

If you're using a stock cooler or a cooler that is rated for a processor much higher than the one you're currently using but it's barely keeping your CPU from overheating, the problem is not the heatsink but the fan that is on it.  The standard fan on many heatsinks offer little or no airflow across the most active area of the heatsink (the middle)  as shown in the image below.

 

                                                                            

(Heatsink was left to gather dust with the fan running at full rpm 6300)

   

As you can see,that dusthas only gathered around the rim of the heatsink.  This shows that airflow was only present on the edges of the heatsink. 

This means the CPU wasn't cooled efficiently because the hottest part of the heatsink received little or no airflow.

 

 

The fan used on this heatsink is a standard (used on just about every heatsink) one.

 

 

  

 

 

 

 

                                   Fixing the problem.

 

This problem can easily be fixed by buying a 60 mm to 80  fan adapter and a 80mm case fan.

 

 

Fan adapter: The shapeAnd height of the fan adapter Will direct a lot more airflow to the most active area of the heatsink. This will make your CPU temperature 5 to 10° lower.

 

(A case fan Produces less noise and moves more air than the standard fan on the heatsink)
