Ive replaced the stock fan on the zalmon cnps9500 for an arctic cooling f9 pwm to see if lower noise/improved cooling could be acieved.
stock fan spec:
92mm
1,350rpm ± 10 % ~ 2,600rpm ± 10 %
Noise Level 18.0dBA ± 10% ~27.5dBA ± 10%
no CFM data.
7 blades
arctic cooling f9 pwm
92mm
600 - 1800 RPM (controlled by PWM)
Air Flow: 35 CFM / 59.5 m3/h
no noise level data
9 blades
test system see sig (overclocked quad [email protected])
test software prime95 & wprime v1.55
the zalmon stock fan was set at max speed for all tests
the arctic was set using pwm for all test via bios at (45c lowest setting)
prime95
results:
stock fan: f9
max t 45c 46c
wprime
1024m
43c 46
32m
37c 36c
idle temps:
both @21c
a noticeable noise reduction using the arctic f9 even at full speed over the stock zalmon fan. temps are pretty much similar with slightly higher temps with the arctic but it does only spin at a max of 1800rpm over 2500 rpm of the zalmon.
is it worth it? only if you want a really quiet machine and auto fan control.
more data is available if required.
next test fan:

92 x 92 x 38mm pwm.
