That chirping sound is actually the most pleasant noise I've had coming from a computer. It's not there often enough to be bothersome and is almost charming
I suspect most of the people who has been been complaining about the fan noise have either a water cooled GPU or a very very quiet one, because the fan noise isn't bad at all, though it is there.
After running many many stress tests on my computer I don't hear any coil whine anymore, except for a few seconds whenever i overvolt my GPU. I've been doing that when needed to get through AC3 without crashing.
Hi guys,
I putted my system together a few weeks ago. Sad news is, since a week ago I got some annoying noise coming from my PSU, it's like a constant whistle. When the fan starts up it sounds like it is trying hard to start for a thousand times (with a little beep every time), and then kicks in with a whistle. It's a new Silverstone SFX 600W version. I made a short video of it (with my phone so it's not that good quality) and posted it on Youtube: http://youtu.be/EIxPqfESkRE. I'm wondering if there is a fix for this other than replacing the fan itself. Because I'm guessing this is not RMA'able. Any of you guys that have the same problem?
so what is the cure for this coil whine plaguing some of the PSUs you guys have mentioned?
Better air cooling? Quality durable wires? RMAs?
Not yet.Was the Silverstone SX500-LG released?
Barely. If you have a long GPU, you can just about fold the wiring out of the way as long as the GPU does not have a backplate. The connector PCB cannot be pushed further inside the chassis like on previous Sivlerstone PSUs, so either you lose the backplate, use a shorter GPU, modify the plugs themselves to reduce their height, or use a different PSU.Will it fit in a v1 M1 case?
Just catching up after months away...
Was the Silverstone SX500-LG released? I can't seem to find it anywhere. Will it fit in a v1 M1 case? How does is compare noise-wise with the 600watt?
sorry if all of this has been answered already- its been awhile... Just starting contemplating another M1 build for the winter...
Someone over on OCN asked them about it and they said there was no changes.
Obviously not completely true or there would be no need for a revision but it may be some minor internal change.
Right, we won't know for certain unless someone opens it up, or if the rep comes around and lets us know about it.
I've had the 1.1v and 1.0 the only differences I really noticed were that the fans were a bit quieter once it started running. The difference was really negligible and I'm not even sure thinking back if it really was quieter. Also when the psu turned off it sometimes didn't make a coil whine noise and when it did it wasn't very loud.
The coil whine problem that I've experienced with the 1.0 is only when the psu gets heated up but not enough to have the fans running and it makes a slight whine with the fans budging a little. That whine is still there in v1.1.
On either unit, once the fan turned on did it ever turn back off again when the PC was still running (not during sleep, or shutdown), or did it always stay running?
Coil whine isn't caused by heat, it's caused by combining certain components (like PSU, motherboard and GPU) that cause a certain frequency in a coil which allows the coiled whire to resonate. The only real solutions are to find what component is causing it (CPU, GPU, motherboard, ...) and replace it or put a dab of hot glue onto the coil that is resonating. But this isn't easy.
WiSK has already speculated (more than once in this thread) that the white paste that is put onto the coils to prevent this, is not done correctly and by putting a good amount of load (>300W) on it for long periods of time (overnight) could allow the white goop to become a little more "goopy" and attach properly to the coils.
Atleast a few people have said this reduced their coil whine or eliminated it. Other noises like a chattery fan or clicking noise is related to the fan and not coil whine.
I've also personally tried the "overnight" load which hasn't personally worked for me.
for revision 1.206a we're changing the cute bird chirp to a funny cow moo!
the PSU now makes a high-pitched frequency sweep (very slowly from high to low) right before the "birdy chirp"
Is it like this consistently at load? At what load? I hear a lot about strange noises (above), chattering and general loudness at load, comparable to the 450w.
Plus Silverstone wouldn't consider Noctua.
