Before you install your Matrox Axio card set
program (see “Monitoring Your Matrox Axio System” on page 245 for more
information).
To provide as much airflow as possible between the cards, you must install a fan
as explained below:
• Position a fan directly facing the end of the Matrox Axio cards with the PCI
retainer brackets. You should make sure the fan directs air between the
various circuit boards. When installed, this fan works in conjunction with
your PC exhaust fan (located at the back of the PC case) to blow warmed air
away from your Axio cards.
• Choose a fan that has a minimum rating of 40 CFM (CFM stands for cubic
feet of air displaced per minute and is a measurement standard for fans). An
example of a fan that meets this requirement well is the Sunon model
KD1208PTB1, which is a 12 VDC fan with a rating of 42.5 CFM.
• Make sure to mount the fan as close to the cards as possible. In most
systems, you should be able to place the fan directly behind the card guide
slots.
• Make sure to close your computer’s cover once you’ve finished installing
your hardware. This ensures that the airflow generated by the fan is directed
through the cards and does not escape through the top of your system.
²Caution Fan installation should be done by a qualified technician. Improper
installation procedures can result in damage to your Axio components and/or your
computer system. Matrox Electronic Systems Ltd. is not responsible for any
damage caused by faulty installation.
