I’ll take a noisy fan over a leaky roof any day, but those old roof units really can sound like you’re prepping for liftoff. Honestly, I’ve seen a few gable fans get overwhelmed after a big thunderstorm—especially in older homes with weird attic shapes. If you’re in the Midwest and storms are a regular thing, I’d lean toward the roof fan for even airflow, but only if you’re sure the flashing and seals are solid. Nothing worse than trading noise for water stains...
I hear you on the roof fan noise—my old house had one that sounded like a jet engine every time it kicked on. But yeah, I’d still rather deal with that than water dripping through the ceiling. One thing I learned the hard way: if you go with a roof fan, really double-check the install after a big storm. Even “pro” jobs can miss a spot with the flashing, and it doesn’t take much for water to sneak in. Gable fans are quieter but, like you said, sometimes just can’t keep up when the humidity spikes. For what it’s worth, I added some extra soffit vents and that seemed to help balance things out a bit.
That roof fan noise is no joke—mine used to rattle the whole attic, and I’d always brace myself during storms, hoping the flashing held up. I totally get preferring a little noise over a leaky ceiling though. When I redid my setup, I tried adding more soffit vents too, but honestly, I still had hot spots in the summer. Did you notice any difference in your energy bills after tweaking your venting? Sometimes I wonder if going with a solar-powered fan would’ve been quieter and greener...

Honestly, solar fans are quieter, but they don’t always move as much air, especially on cloudy days. I tried one at my aunt’s place—helped a bit, but the heat still built up in July. Energy bills didn’t change much either. If noise is the main thing bugging you, maybe check if your current fan is out of balance or has loose mounts? That rattling can sometimes be fixed without swapping the whole thing.
I’ve seen solar fans installed on a few properties, and honestly, they’re hit or miss. On a sunny day, they’ll hum along quietly, but if your attic bakes during a heatwave and there’s cloud cover, you might not notice much difference. Roof-mount fans tend to vent heat better than gable units in my experience, but they’re also more work to install and patch if you ever need to remove them. Gable fans are easier to swap out or upgrade, though airflow can be less efficient depending on attic layout. If noise is the main issue, sometimes just tightening up the mounting hardware or adding some rubber washers can make a surprising difference—no need to reinvent the wheel.
