hi, currently i have the following noise producers inside my case (Antec SX1030):
1) 28 dB - Thermaltake 60mm CPU fan
2) 30 dB - Antec 80 mm case fan
3) 30 dB - Antec 80 mm case fan
The following i'm just guessing at noise levels (they are all pretty quiet, i don't hear the vid card or PSU fan):
4) 25 dB? - PSU fan (Antec PP-303XP PSU)
5) 25 dB? - ATI Radeon 9500 gpu fan
6) 25 dB? - Quantum hard drive (not at full rotation, just while doing normal stuff, i.e. listening to mp3s)
Today i replaced my CPU fan with the one listed above. My old one was the Delta fan that came with my Global Win CAK38 HSF, that was rated at 47dB.
The problem is that the noise level of the computer doesn't seem to have lowered at all!
Before i went out to buy the new CPU fan, i made sure it was the Delta fan making the most noise by turning on my computer without the Delta fan connected to the power supply (don't worry i immediately turned the system off...heatsink didn't even get warm). It was indeed the source of most of the noise...without the CPU fan, my computer sounded more quiet with me right next to it, then it would be normally with me right outside my room.
So with the new fan it sounds just as loud, i can still hear my computer as i come up the stairs towards my room. From reading one of the previous threads, i calculated the noise from my computer.
With the Delta fan, it should have been around 47.2 dB (not accounting the case absorbing some of the sound)
With the new Thermaltake fan, it should be 35.5 dB (not counting the case)
That's more than a 10 dB difference! but i sure can't hear the difference...
so what do you guys think is the problem? The Thermaltake fan has a date on it, Aug. 2001...so it's been sitting in a warehouse for some time now, is it possible that i have to lubricate the fan as i have read on some other sites/forums?
oh and if i do need to lubricate the fan, what's the safest/best stuff to use and best method?
