Reuse yours / Partner pick
Cooling
Airflow Fan
Any quiet 120–140 mm PWM or USB fan you own — or a partner pick if you need one.
What it does
PC-style fans are cheap, silent and ideal for this job. Reuse one you already have; the Studio calculation model estimates the airflow your room needs, while your own timer, smart plug or controller operates the fan.
Moves night air through the bank, then gently releases stored coolth by day.
How to source it
Reuse yours
Reuse a quiet PC or USB fan you already own (120–140 mm works best).
Partner pick
Silent 140 mm PWM fan category
A quiet low-voltage fan set from an airflow partner. Standard PC or USB fans can be swapped in.
When it is recommended
Every build — natural convection alone rarely moves enough heat.
