Allowed to remove fans from Victors? Leave fans off Talons?

[computerish]

We're trying to fit an unusually large number of motor controllers into an unusually small space this year (as I imagine a lot of teams might be). We're wondering if it's allowed to leave the fans off of the speed controller and provide our own cooling by having a couple of side-mounted fans blowing across all the controllers.

Is it legal to remove the fans from Victors (either the old 884 or the new 888s)?

Is it legal to leave the fans off of the Talon speed controllers (since they already have a sizable heat sink)?

Thanks!
