Spire Diamond Cool II

1. Introduction

The increasing popularity of AMD processors, has increased the demand for extra cooling solutions beyond that offered by the stock coolers, which in their majority are not adequate for OC. On top, PC case styling has also become a priority for the end users. To "answer" these calls, various manufacturers have released their CPU cooling solutions. Spire is among the better known cooling solution manufacturers with several AMD and Intel based coolers. Today, we will be reviewing one of Spire's latest products, the SP741B3 Diamond CoolII, an AMD based cooler, which among other things, promises to give a cool look to the interior of your PC case.

The Cooler...

The SP741B3 Diamond CoolII basically consists of two parts; the UV-reactive 90mm Spider-Fan and the copper heatsink. The UV-reactive fan will give a cool look to the interior of any PC case with the proper UV light installed. Enough about the "modding" aspect of the cooler and on to the technical.

The fan works at 2300RPM creating a 25.78CFM air flow, while the noise levels are relatively low, at around 21.0 dBA.

The all new Diamond CoolII

No innovative designs are noticeable here, just the standard design from Spire that we have become used to. Under the Spider-Fan, resides a solid copper heatsink, with 40 fins and four copper heat-pipes which run through the fins to the other end of the heatsink, responsible for keeping the base cool and hence CPU temperatures at low levels.

4 copper heat-pipes are responsible for the heat dissipation...
