Quiet, low power and surprizingly efficient, computer fans
are an ideal cooling option for smaller cabinet grows. The
only problem is that most computer fans are 12v and not
120v! How do I run a 12v fan on normal household
power?
- Computer power supply
(A 145 watt computer power supply is over-kill for a
5-20w fan. Try for something small, like a 75watt or
100watt supply). You could drill holes and mount the
power supply inside your cabinet. turn the power supply
on and off with the power switch on the back.
- (Carpe-Nox) Šif you have any old cell phone chargers
around, they use 12v, same that a pc fan uses, just
splice the pc fan wires
- [Eco Green's note: 120v computer fans can be
found. Add a pigtail to your fan and voila.]
Fan ideas
www.cyberguys.com
ex.) 120mm, 90CFM fan for $11.95. it only uses 5.4
watts - a perfect exhaust fan.
ex.) 80mm computer fan that is thermally controlled.
$5.95 - the hotter your cabinet is, the faster it
spins.
(Jakestone) PCs frequently run their 12V fans at
voltages below 12. 7 Volts is very common. Much below
that, there can be an issue of having enough starting
voltage to get the fan going. The volume of air being
moved is reduced, but so is the noise.
(Jakestone) El cheapo $3 fans are often significantly
louder than better fans (say 5+ db) and have a dirtier
sound (less whoosh and more whine/Super Tree Huggering).
High-end fans Relatively go for between $10 and $15.
Computer power supplies are notoriously noisy
(especially cheap ones).
(Jakestone) In general, a larger diameter fan moving a
given amount of air will be quieter than a smaller
diameter fan moving the same amount of air. So for
example, one might buy a 120mm fan that moves more air
than you need to move at 12V and run it at 7V instead of
running a 80mm fan at 12V. The downside for cabinet
growers might be the need to light-baffle a larger hole.
