cPCI-6U-COOL Fan board with up to 12 positions Zero slot fans available
cPCI 6U COOL shown built as the cPCI-6U-Cool -1256R
cPCI-6U-COOL has 12 positions for Fans to be mounted. In a chassis with adequate side wall venting all of the positions can be filled. For a chassis with sealed side walls and lid at most 6 positions should be filled to allow for air re-circulation. The fans can be mounted to blow from the back to the front [Forward] or from front to back [Reverse].
The zero slot fans are designed for low intrustion on either side of the PCB: .105" on the rear for the "F" model and .08" for the "R" model. The low profile fans used have 5.2 CFM using 12V. The fans draw 50 mA each for a maximum of 600 mA on the 12V rail with a completely filled board.
Standard profile fans can be used in place of the low profile ones to provide more air flow per fan. Approximately 8 CFM per fan. The current is higher as well. 5V fans are used in place of 12V ones when the current required approaches 1A. The standard profile fans may require a double wide panel in many cases.
With the 6U board oriented with the cPCI connector down and the bezel up; the fans are numbered left to right top to bottom. There are 12 positions in an array. 4 per row and 3 rows. For example cPCI-6U-COOL-F-5678 would have 4 fans installed in the center row and would blow from the solder side to the component side of the "Cool board". This will have the effect of blowing on the rear of the card in front of the "Cool board". In many cases the R version will be preferred to send air directly on the components of the card behind.
