Through use, I found that I really like the automatic temperature controlled fan speed mode of operation. Granted, if you use Folding@Home or SETI@Home, the fan will most likely be at the same speed most of the time. But, for those of you who do not keep your computer at 100% CPU usage the whole time you are using it, you will notice the difference. Even with a stressed processor, one might notice a drop in fan noise if the temperature drops (night time computing, etc.).

The manual fan speed controllers work as promised. Personally, I would hate to give up a whole 5.25" bay just for a single rheostat. I feel the PCI bay controller is a better option. Thermaltake was trying to cover all their bases when they decided to ship both. I still think that was a great move because even though I treasure my bays someone else might treasure their PCI slots.

Let me move onto testing. Ambient temperatures for all tests were 24.8°C. A 'closed case' was used in every test to simulate an average persons computing experience. Temperature was measured with the temperature probe located in the CPU socket that makes contact with the bottom side of the Athlon. This method of temperature monitoring only provides temperatures in integer values so accuracy levels are not very high. However, these tests will give you a 'ballpark' figure. Here are the test system specifications:

Test Machine
CPU AMD Athlon 1800+
Motherboard EPoX 8RDA
Case Closed Case, 2 Case Fans, standard intake and exhaust

'Fan High' and 'Fan Low' indicate the level fans were set to using the voltage adjustment tools provided by the manufacturer of the heatsink. So, the 'Zalman CNPS-6000Cu (Fan High)' is the CNPS-6000Cu with Zalman's fan control unit set to it's maximum setting. Remember, this doesn't necessarily represent a high or low volume, as the Volcano 11+ at maximum speed is considerably louder than the Zalman at its maximum speed.

While the Volcano 11+ at high speed beats out the pack, the low speed fan falls far behind and it just gets worse under full load.

The Volcano 11+ clearly takes the lead by 3°C with the fan on high. However, the fan on high is a lot louder than the rest of these heatsinks. Most of these heatsinks cannot be distinguished from the two Sunon high output case fans in the case used for testing, but the Volcano 11+ could with fan speed at its maximum (4800 RPM).
