The fan is branded "Fanner Tech", which is part of the
same company as Spire.
The translucent blue fan is a low speed ball bearing model that glows under
UV light. It is rated for either 0.13A or 0.15A depending on which set of specifications
you believe. Detailed specifications for the fan could not be found beyond what
Spire publishes for the Verticool.
The fan is identified as a Fanner Tech product, but a quick visit to Fanner's
web site shows that Fanner and Spire are quite closely related; most links
point to a pages on Spire's web site. It is not clear which company owns which,
or if there's a larger, unidentified parent company.
Spire refers to the fan as a "Spider fan" an appropriate description
of the unusual frame. Its main characteristics seem to be that the motor supports
are on the intake side of the blades and the frame is only half as high as usual.
What advantage this confers is unknown. Perhaps the smaller frame allows more
air to be drawn through. Whatever the advantage, it's mounting holes conform
to the standard 80mm layout, so replacing the fan should not be difficult if
it turns out to be a lemon.
Spire's web site links to a
generic instruction sheet. Not surprisingly, it does a poor job of covering
the specific nuances of the Verticool, but it wasn't difficult to figure out.
The basic procedure is to screw the appropriate pair of mounting brackets onto
the base of the heatsink, which is then screwed into a metal backplate (included)
underneath the motherboard. The stock retention module, if there is one, needs
to be removed from the motherboard before installation. The screws are sprung
to prevent excessive force from causing damage during installation and to ensure
that the heatsink is kept under the proper amount of tension.
A single screw on each side of the base holds the appropriate brackets in

This photo illustrates the difficulties with mounting the Verticool on K8
systems. Can you spot them?
The installation system for K8 processors comes across as a bit of an afterthought,
and there were a number of issues that made for a less-than-smooth experience.
- First and foremost, the Verticool orientation whether the
fan blows vertically or horizontally depends entirely on how the motherboard
is laid out. If this means the fan blows up at the power supply rather
than towards the back panel exhaust fan, that's too bad. Socket 775 does not
suffer from this problem, since its four mounting holes are arranged in a
- Each of the K8 mounting brackets are attached to the base with a single
screw, located directly behind the main spring-loaded mounting screw. It is
impossible to keep the screwdriver squarely in the screw head when attaching
the bracket. Extra care needs to be taken to avoid stripping the screw head.
- The frame of the fan completely blocks the head of the K8 mounting bracket screw, requiring
the fan to be removed and then replaced once the heatsink is fully installed.
