Hi, I just put together my dream system, and right now i'm running my
Swiftech MCX462-V heatsink with a vantec stealth 92mm fan, and my temps are
a bit high for my taste 131f/57c. Could I have some suggestions on a good
92mm (pretty quite) fan?
TIA
Processor: AMD AthlonXP 2000 overclocked to 1760MHz @ 1.85v
Fan airflow & Processor temperature
noise ratings
22CFM / 14dBa 57.9°C (136°F)
40CFM / 30dBa 49.1°C (120°F)
69CFM / 49dBa 44.9°C (112°F)
Vantec Stealth SF9225L 92x92x25mm
12V 0.07A 1750 RPM 20dBA 28CFM
Judging by the numbers above, you are going to hear the fan that
is good enough to bring those temperatures down.
If you go here, and search on "Panaflo"...

there are a couple of candidates (no RPM sensor ?):
Panaflo 92mm "LOW" 42.7cfm 27dba TL1A Fan 2100RPM

Panaflo 92mm "HIGH" 56.8cfm 35dba H1A Fan 2850RPM
[email protected] $22.98 CDN
Panaflo fans have sleeve bearings, but the claim is, the bearings are sealed,
so the "juices" don't run out like an ordinary fan. You will probably
hear the 35dBA.
Directron.com has a papst(ebm) fan 35.9CFM 23dBA

These use sintered bearings, like some larger AC motors.
Note the voltage range listed in the datasheet - using a rheostat on
these fans might not be a good idea.

A similar fan is the Titan:

I like the Swiftech for the fact that it bolts to the board, and doesn't
have to be removed before the computer is shipped anywhere. But the
design of the aluminum pins looks "arrestive" to airflow, so expect
that to get decent performance, the fan will have to be noisy. Cooling
performance is related to surface area and air velocity, and using
heatsink assemblies with larger volumes will allow a slower fan to
be used. You just have to be careful to check dimensions, in case
an overhanging design conflicts with other components in the case.
