Are trying to get to the bottom of this, or run an inquisition? To be fair, to get to the bottom of it, people experiencing the buzz/whine should publish the same information. I say this because I noticed a similarity between the the non buzzers, myself included - The presence of an x1950, power sucking vid card. This could be a coincidence, but is it not possible that a higher load on the PSU is having an effect? It's fairly well documented that PSUs are less efficient under a low load. If so, that would make this PSU appropriate to some systems, but not others. My interest here is that I'm thinking of replacing my 4 HDDs with 2 notebook drives, which would reduce the load on the PSU.mastabog wrote:
A claim of "no whine/buzz" will look more credible if the claimer specifies the system specs so the reader will have a better idea, this includes:
- fans model
- number of fans
- voltage/rpm of fans
- hdds
- video card (or video card cooler if it was replaced)
- distance to the unit for normal usage
- unit position (e.g. under the desk)
In my case (pardon the pun):
Heavily dampened Sonata II (A buildup of foiled backed butyl, self stick floor tiles and accoustic foam.)
MSI P6N SLI Platinum
e6600 stock speed
Zalman ZALMAN CNPS7700-CU HSF, dialed down to minimum fanspeed
Passively cooled x1950Pro 256
4) WD Caviar RE WD1600YS
1) Nexus 120 case fan dialed to about 80% via a Zalman fanmate
4 x 1 gig Kingston DDR2 667
Since my last post in this thread I have suspended the HDD's, though they remain the noisiest element of my system.
The computer is about two feet from where I sit, directly at ear level. I hear zero whining or buzzing from the PSU.
