Re: [CAD_CAM_EDM_DRO] Re: Best way to mount Gecko modules ?

Would that be enough area to dissipate the heat? Say, 3 hours use, on a
warm day? Even with a fan I'm not thinking so. Might shorten the life I
think. Would be worth it to go big I think.
Even Intel's Slot-1 (older) CPU sink is only 2"x5".
I'm thinking 12"x24" Minimum (w/ Fan) for 3 of them. Even with the good
efficiency it has to deal w/ some amps under load.
Would this be a little overkill?
