User
Manual
NOCTUA NV-FH2

The NV-FH2 is a flexible, premium-quality 8 channel PWM fan hub that is ideal for powering up to eight fans in
home, office or multi-purpose ventilation applications using an external power supply with 5.5mm barrel
connector such as Noctua’s optional NV-PS1. It’s compatible with 5, 12, and 24V fans with 4-pin PWM and 3-pin
connectors and supports up to 60W total power draw.
Topped off with CE, UKCA and UL certifications, full compliance with all applicable safety standards as well as
Noctua’s 6-year manufacturer’s warranty, the NV-FH2 represents the gold standard in highly robust
multi-purpose splitter boards that work just as nicely inside a PC as in other ventilation applications.

Resettable fuses
For maximum safety, the NV-FH2 has auto-
resetting fuses on the 4-pin input (1.85A) and each
individual 4-pin output (0.75A) so that it can
automatically shut down in case of overcurrent or
short-circuits on one of the connected devices or
cables. If one of the fuses has blown, simply
disconnect the NV-FH2 from all power sources for
1 minute to reset it.
Make sure that current ratings and maximum
operating temperature are within the specified
limits before reconnecting.
