I'm asking all the builders who already finished and used their MB-6582 whether an actively cooling fan is required in the Pactec PT-10 or not. I'm not asking if it "looks cool", rather than is it really needed to avoid overheating SIDs. My plan is to use heat spreaders (like Hawkey) in combination with ventilation slots below the voltage regulators (seen on pics from Wilba) and use the backpanel space (where the fan was intended) for additional 6.3mm audio-in and the mix-out jack.
