I believe a major consideration for sucker and pusher fans is that suckers can mounted close to the core and effectively pull air through, while pushers need space between the blades and core to push the air through. The popular Merriah (sp?) pusher fan motors are so large/long it's tough to get that space needed to best develop air flow through the core. Sent from my iPhone

If you are still experiencing overheating problems, you may want to try the solution taken by Doug Mann many years ago. If I remember his words, they were something like "If two vents are good, four vents must be better!" (Going through old folders when I found some of his potos...)
