Speeze CopperSnake II Pentium 4 heatsink
 

Even at our middle heat test setting the Speeze CopperSnake II is fitting in the
middle ground. For an air cooled heatsink that is not massive and not too heavy this
level of cooling is impressive. It even comes in a dynamic colour to brighten up the
inside of your computer case. We can only say well done to Speeze on this Intel
