Glacialtech UFO V51
- Intel S775/S1366 / AMD AM2/939
- Heatsink : 804 gram
- Two 92mm fans rated at 1600rpm
- No Price Info Available

The UFO V51 comes in two versions, one with PWM fan, rated at 800~2500rpm or the normal one we’re testing, which has a 3-pin connector and is rated at 1600rpm (measured 1630rpm@12v, 624rpm@5v).

Inside the package you’ll find mounting brackets for all the popular AMD/Intel platforms out there, including S1366. The thermal paste is provided in a small plastic bottle. The user manual is quite detailed.

The heatsink features nickel plated copper base (with mirror finish!), 4 heat pipes transport the heat to the tightly packed fins which are cooled by two custom 92mm fans, which are setup up in push/pull configuration. While the total size of the heatsink seen from the top is large enough to fit a larger 120mm fan, Glacialtech opted for two smaller fans…



Installation is time consuming, but provides a tight fit. Two metal brackets are installed on the motherboard, then you secure the UFO V51 in place with the metal clip, you’ll have to use the included inbus key. Compatibility issues on the mainboard are not likely as the main body is raised quite high; but which might be an issue in smaller cases is the overall dimension. In the Antec Sonata 2 it was a tight fit.



We’ll compare the performance of the UFO V51 to another large top-down cooler, the Scythe Zipang which features a huge 140mm fan.



The fans on the UFO V51 are quite audible at full speed, performance is more than acceptable though, undervolting the fans to minimum speed makes them almost dead quiet, but performance suffers noticeably, a setting in between 7~9v would provide the best performance/noise ratio. Compared to the Zipang the UFO V51 trails slightly at similar noise levels; compared to the smaller Igloo the UFO V51 doesn’t really stand out all that much, it takes 9 extra decibel of cooling power to drop 1.5°C… not very convincing.

In summary here are the strong/weak points of the Glacialtech UFO V51 Silent:



+ Acceptable performance/noise ratio
+ Solid installation (which does take some time)
+ Wide platform compatibility

- Large heatsink, yet small fans used
- Performance not remarkably better than smaller Igloo 5750
