The Spire Thermal Eclipse II is a good example of well-designed and efficient heatsink. The product retails in a complete package with two 120mm fans included. It can be easily installed without needing to deal with many screws and installation diagrams. It has also a aesthetically pleasing design with its black-nickel coating and a great finish.

The heatsink was also very efficient, at least when mounted in our Core7-920 system. It's dual fan configuration kept the temperature of our CPU at low levels even under overclocking conditions. Of course, after having tested so many cpu coolers, the Thermal Eclipse II doesn't introduce any new levels of performance. It remains competitive enough to deserve your attention if you are looking for a relatively compact in size heatsink that will do the job. And if your PC case is not the larger available out there and it is already crowded with many devices and add-on components, then the size of this cooler could be an advantage for you.

The moderately loud noise output of the Thermal Eclipse II should not be an issue for you, unless you are watching movies on your PC. Though the two fans are not PWM compliant, you should try a single-fan configuration, with a small performance trade-off according to our tests.

Last but not least, the Thermal Eclipse II is priced at around $53. That's a little bit higher than what you may have expected, since some other solutions would cost you $5~10 less. In spite of this, the Spire's Thermal Eclipse II remains a great performer.
