The Test Bed:
Here are my system specs to simplify things:
Abit KT7 (Voltage Modded)
AMD Thunderbird 1300 @ 1600 Voltages: CPU: 1.85volts : I/O 3.3volts
Windows XP Pro
Thermalright SK6 HSF
512megs Tonicom PC166 SDRAM
Thermaltake Memory Cooling Kit Installed
ATI All-In-Wonder Radeon 7500
Maxtor DiamondMax 15.3gb 7200rpm HD
Creative 52X CDROM
LITEON 24X burner
Sound Blaster Audigy X-Gamer
D-link 538TX 10/100 NIC
Enermax 350W PSU
3COM Cable Modem 2.5meg Cable
1- 120mm 135cfm YS-Tech Side Intake
1- 80mm 50cfm ADDA Front Intake
2- 92mm "Reviewed" Top Blowhole Exhausts
The test setup contained two of the reviewed fans as blowholes.
The Fans:
Fan #1: Sunon 92mm Case fan (Model# KD1209PTB1-6)
Voltage: 12VDC
Type: Ballbearing
Current: 0.21 Amps
Wattage: 2.5 Watts
RPM: 2700rpm
Airflow: 49.5 cfm
Noise: 34.5 dBA
This was my first 92mm blowhole exhaust. A very quiet fan when you consider
the airflow numbers. Worked quite well in my case.
Results:
Room Temperature: 20 degrees celcius
System Temperature: 24 degrees celcius
Cpu Temp Idle: 27 degrees celcius
Fan #2: ADDA Ultra-Speed 92mm Case fan (Model# AD0912UB-A71GL)
Voltage: 12VDC
Type: Ballbearing
Current: 0.39 Amps
Wattage: 4.7 Watts
RPM: 3300rpm
Airflow: 60.0 cfm
Noise: 39.4 dBA
With the installation of ADDA brand fans, I really missed the quiet whisper
of the sunon variety, although the airflow was a lot better, and the case
and cpu temperatures were considerably better. One thing with ADDA fans
is the characteristic whine, kinda high pitched and really annoying over
time.
Results:
Room Temperature: 20 degrees celcius
System Temperature: 22 degrees celcius
Cpu Temp Idle: 24 degrees celcius
Fan #3: YS-Tech SUPER 92mm Case fan (Model# FD1292327B-2F)
Voltage: 12VDC
Type: Ballbearing
Current: 0.21 Amps
Wattage: 5.9 Watts
RPM: 4000rpm
Airflow: 73.3 cfm!!!
Noise: 47.7 dBA!!!! HOWL!!!!
These fans are crazy!! The pure power of these is terrifying to hold
in your hand. One slip or anything and you are sure to have a permanently
damaged finger, and I am NOT kidding about this. The noise is unbearable.
The screaming howl of this fan would drive the calmest man nutz, so, I
kept this one as the option to keep in my case =). But I installed a rheobus
(upcoming review), to tame the power and make the noise reasonable. These
fans literally shake the whole case, so if in any case you have a loose
connection or screw, you will find it in about an hour after installation.
But, in all actuality, the case temperature brought about by the installation
of these badboys is amazing and worth the noise, now tamed.
Results:
Room Temperature: 20 degrees celcius
System Temperature: 20 degrees celcius
Cpu Temp Idle: 22 degrees celcius
