I have an idea for a LTT Labs experiment video
test whether a 'silence' optimized case like fractal define series is actually quieter than a airflow optimized case
the test would need to involve as many examples as possible of multiple types of cases which LTT must have in their warehouse
controls could be;
having the same fans in the same orientation and position,
having the fans controlled by an external device like a NZXT Grid+ or similar device.
same components in all the cases.
bonus points for with and without a custom water loop for even quieter systems with low temps
