(not a bang on you or anything as allot of people go with the headline not the facts here and I ended up doing some real research here) Sorry, but this is a bit of a pet peve as it is one of those 'common knowledge' or conspiracy theories deals that also happen to be more fiction then fact.

If this fails though, I will probably end up resorting this However when I pay $2800 for a machine and it has an extra port for an automatically controlled fan with better/colder airflow, I dont want to settle for less. Great suggestion, I actually used something like this on my thing o matic and it does work great. I'll have to test the current and everything though to make sure it doesnt draw too much. I could probably run these two fans in series with 1 port. I also ordered 2 12v fans of the same dimensions accidently before realizing the bot runs 24v (thing o matic is 12v and i made assumptions).

Im assuming the fan port activates automatically when I choose PLA as the printing material in makerware. I was thinking of maybe using the output on the board to trigger a relay for the fans using an external power supply. David, could you give me a link to this thread? Also, I have taken the load considerations.
