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 place.

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.

  1. 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 square.
  2. 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.
  3. 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.

The screw to attach the bracket to the base is blocked by the main mounting screw.
