Featuring a trio of low-noise 230mm fans mounted at the
front, top and side, as well as a 140mm fan mounted in the rear, the Cool
Master HAF 932 is designed to push a lot of air through its cavernous
The side fan can also be swapped out for four more 120mm
The side fan can be replaced with up to four 120mm case fans, and the
top fan can be swapped out for another three 120mm fans, giving room for as many as
ten fans to be run simultaneously. Most fans don't draw that much power, so you're
limited by molex connectors or 3-pin fan headers.
The included top 230mm fan can be replaced with up to three 120mm
All three 230mm fans are Cooler Master branded, run at
700 RPM and are rated at a very quiet 19 dBA. Because of the size of the fan a
high RPM isn't necessary to move a lot of air through the HAF 932 case. The fans
themselves use native 3-pin fan connectors, meaning they don't have PWM support.
Each fan is supplied with a 4-pin molex connector as well as including a
pass through female connector so that other devices can be powered
Very thoughtful, and useful given that modern power
supplies are now splitting the number of molex connectors with SATA power
The rear 140mm fan spins at a relatively low 1200 RPM, and again this uses
a 3-pin design with supplied molex adaptor. This fan can also be traded
out for a smaller 120mm fan.
The lower PSU bay is situated
beside another mounting area that can fit either a 120mm fan or a longer power
supply. There is grating in the bottom of the chassis for either the dual-fan intake for
a PSU or for a fan to pump cold air through the bottom
of the case into the chassis.
This grate has
room for more fans or a longer power supply
If the PSU is moved into the upper bay a second fan can
be dropped in easily, though no extra fan screws are provided.
While the large, low RPM fans on the HAF 932 produce such low amounts of noise as to be inaudible from
a few feet away, the grating on the top, front and side of the case won't provide
any sort of sound insulation from noisy system components inside. There will be enough
air moving into and out of the HAF 932 system that most users probably won't
have to run components at full blast in order to keep their top-end hardware running
cool. Users intent on building a silent PC might find the Cooler Master HAF 932 the wrong
option. It lacks the solid, sound-insulating side panels and a front door panel which
deaden annoying PC noises.
A more distressing problem with the grating around the
fans is the lack of any kind of dust filter to keep the insides of the case
clean. Given the amount of air the HAF 932 will be pushing through it, be
prepared for regular compressed air sessions to keep your parts dust-free.
