ideally, you have toAre you guys blocking up unused drive bays to increase airflow over the bays with HDDs?
I'm detecting a lot of airflow through the empty bays and barely any across the bays with HDDs. Thinking about stuffing some insulation foam to block up the unused bays for now.
When I bought 2U, 3U, and 4U.. all the HD caddy/tray has plastic buffer
if you do no have, you can block partially, with plasti board (corrugated plasti board)
, I did this for my first old SM 4U where the seller only gave empty HD caddy without plastic buffer
