Conclusion: The test machine consists of an AIUGA 1700+ (1.47Ghz) Athlon XP paired with a Soltek SL75DRV5 motherboard and 256MB of Samsung PC2700 ram. The case is a Tsunami Virgo with two case fans, one drawing air in from the bottom and a second exhausting air out of the back. The CPU chip is cooled by a Thermaltake Volcano 6cu cooler (4500rpm).
Conclusion: So what, if anything can we take away from this?Â Well, if you're willing to sacrifice a relatively minimal increase in temperature then you can cancel case fans out of your computer's noise equation.Â At 20dB the Zalman fan in "silent" mode was effectively just that: noiseless. Something toÂ notice is the increase in both the case and CPU temperature when all case fans were disconnected.Â Just goes to prove that a steady stream of fresh air into a case results in a...
Pros: Cheap, Cheap, Cheap!, Effectively silent in "silent" mode at 20dB, Only slight temperature increase in "silent" mode
Cons: In"normal" mode fan is louder than competitor but is still outperformed, No variable fan speed control, Switch from different modes requires hardware modification, Slight temp increases!
