Cooling Fins

Copper Top

CoolerMaster has once again brought us a product that excels in looks and will catch the eye of everyone who sees them. The CM Sphere is shaped like a round globe and has many radiant fins to help dissipate the heat as well as being made of solid copper alloy. The CM Sphere has an internal fan that spins at 22RPM's and is very silent with a decibel level under 22dBA, which you can barely hear even on our open test bench.

The heatsink base itself is bowed just slightly to make a convex curve that creates for a better contact surface with the CPU. The tension between two slightly convex surfaces creates a contact resolution that is better than two concave surfaces, because that leaves a big gap in the center of the connection. Many professional PC enthusiasts lap their CPU and heat sink, to eliminate the three things that can cause bad contact.

The first is the concave part, which bows out slightly, the next is the concave, or bowed inward leaving a gap in the center, and lastly and the worst scenario the wavy product, that has various high and low spots. The reason that the wavy is the worst is that contact cannot be made evenly in enough space to make a solid bond, the concave part will be missing a space in the center, but there will be contact around the edges for a decent bond.
