Oy! Some activity since I last posted
. I read all the new posts, thanks to everyone who posted. I believe some things are worth mentioning to clear out some confusion, although not entirely since all this is quite subjective.
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
- video card (or video card cooler if it was replaced)
- distance to the unit for normal usage
- unit position (e.g. under the desk)
... basically, all components that make some noise and items of interest that affect sound propagation/anplitude.
Some users are very picky and sensitive to buzz/whining sounds, like myself, and could hear it in a silent system (e.g. passive everything except PSU, and inaudible fans at <600rpm like my system).
Another point is that some whine/buzz sounds are on a different frequency than that of the fans (<3khz) and hdds (~7.2khz) and with a sensitive ear and a picky nature you will hear it regardless of how many and loud fans you have.
Of course, a claim of "no buzz/whine" PSU can really mean there is no buzz/whine and you were lucky to get one that is silent. But since we're all posting in a forum, any other info about the system helps a lot!
There is no point in eliminating your fans and hdds just to hear the PSU whine. If you can't hear it in your system then I'm very happy for you. However, if you want to provide a more accurate opinion to someone looking for such subjective information and who has a (much) quiter system than yours then you might want to do all that and then be able to say: well, i can't hear it with all my fans and hdds on but if i remove or downvolt my fans to inaudble and remove 2 of my hdds and if i sit 50cm away from it then i can hear it ... of course, I don't expect anyone to do that just to help a poor old bastard in a forum
. Would be nice though.
Nevertheless, placing your ear next to the PSU vent just to see if there is a buzz/whine is not that irrelevant as it sounds (see above). Even if you can't hear it because you sit far away and/or your pc is under the desk and/or your fans/hdds make more noise, someone that is a silent-freak with the pc sitting on his desk might be annoyed by that sound.
It is all very subjective. i believe that any other bit of info you can provide helps.
, the 2nd HX520 has arrived today and ... and it still buzzes, the exact same characteristic (a bit chirping, high pitch) but not that loud as the 1st one, I might even get used to it. I'll see if I can get used to it without it getting on my nerves in a few days. If not, I'll RMA it for good and keep the S12-430 ... at least that one only buzzes/whines when I do something - mouse scrolls don't last for too long and 3D load is usually are accompanied by sound (when gaming).
It is definitely a newer model since the 6-pin PCIE cables have a 2-pin extension to them so they can be used as 8-pin PCIE cables. Revision is B2W
(I forgot what revision the first one was).
Thanks again for posting to everyone. It has turned into a quite informative thread.
