Same here. The biggest thing stopping me from buying a truly SFF case like the M1 is that there is no truly quiet SFX PSU that operates without issues like animal noises or broken semi-passive modes. I was really hoping the sx500-lg would be a slam dunk. I would gladly pay more for a great fan that functions properly.

yea, ultimately it depends on the output impedance of the source. i dont have any soldering stuff so i'll need to find a way to hook it up to the original fan

And same here. Think I've stated a few times that I'd gladly pay extra for a truly premium SFX PSU that has the best quality fan and implementation possible. Already spent well over $200 on the ST45SF-G and the SX600-G, and would be furious to rack that up over $300 with the SX500-LG.. all just trying to kill the loudest component in a single build. It's fucking ridiculous and Silverstone should be absolutely embarrassed by all of this.

Wonder if we can price and crowd fund an MOQ through one of the manufacturers to get this dealt with.
Why not? If the middleman won't deliver time after time, then skip the middle bit and get Enhance or other CM to build one to meet a fairly simple requirement - a quiet fan with an efficient controller profile.

I've heard figures of $30,000-$50,000 upfront fees for the PSU OEMs to develop a new design. Then you have various safety certifications. NRTL cert for the USA is $10,000-$20,000 and Europe has its own set of regulations and certifications.
And if I recall, when Necere was asking High Power about their SFX-L design when they first showed it off way back when the MOQ was 10,000 units.

That would be awesome. I would love something that's on par with seasonic quality standards
But, without the aggressive fan profile and coil whine, please. ;-)
A new design isn't necessary and not what people are asking for - simply a better fan/fan profile on an existing design.
It was only 1k IIRC, and we actually approached High Power (among others) with the idea for a slightly larger SFX with a bigger fan, which they went on to prototype and show later on. So even though it was High Power that developed it, and Silverstone and Chieftec that brought it to market, you can thank me for the original idea for SFX-L

True, but I don't know how much more the fan speed can be safely reduced without also reducing heat output by upping the efficiency of the unit.

Sorry about that, don't know why I always get the timeline confused
Wow, 1000 units seems pretty low to me, much more reasonable than I thought.
connected the original fan and it reads reasonable voltages now.

with both x264 and furmark running the voltages didnt really go above 6 so there seems to be a lot of headroom for my setup at least. i'm going to see if mounting on the radiator bracket can still cool it sufficiently
for reference i have a [email protected],1.25VID and a reference gtx 970

Well I honestly don't think the fanless mode is bad compare to say the hx1050 I had on my other system. The hx1050 was the most annoying loud off to full jet engine status I've heard. I ended up going with an evga g2 1300w which spins all the time. I definitely think some of you must have gotten the runts in the litter in regards to the sfx-l. I stopped all my fans gpu fan being the loudest now I couldn't hear anything. Of course maybe if I had the ears of a dog I'd be able to hear something. I hope by people investing into the sfx-l will prove there is demand. Though I wonder how many 300w fanless psus are they selling from any manufacturer compared to a sfx/sfx-l to make thoes small niche fanless psu profitable.

As much as I'd truly love to have a working semi-fanless PSU, I'd gladly take a high-quality fan running at a somewhat higher RPM causing windflow noise versus a crappy fan that makes annoying ticking (chattering/galloping/scratchy) noises at low RPM.

Thank you.
Now...would you mind getting the idea for one that has a proven quiet fan (no sleeve bearings!) with a smart fan profile and starting the process again? ;-) Thank you.
PS - If it was a 650W Platinum unit and still Gold <40W that would be ok too.
well
it appears that this configuration is sufficient to cool the psu while running furmark and x264 simultaneously (i estimate ~300W)
if you have a bad fan and don't care about the warranty you may want to try this
Thanks for performing the warranty-voiding mod. That's good news! Sort of. Can I charge Silverstone for the parts and labor? Seems many of their SFX customers are their first line warranty depots anyhow. ;-)
Sorry to hear that we still can't satisfy some of you guys here, we really tried. We got a lot of flak internally and from management for delaying SX500-LG three months to make it as quiet as possible (to be quieter than our own ST45SF, ST45SF-G, SX600-G, and High Power/Chieftec's standard fan).
I want to remind everyone here that SFX PSUs are really different animals than ATX due to size. With half the volume, SFX PSUs are usually twice as dense power-wise so you can't directly compare a quiet ATX 500W ~ 600W with these "high powered" SFX units.
With that said, if your system power draw does not exceed 300W, maybe you can give our ST30SF a try instead. It has the highest fan-less mode temperature at 50C (compared to 45C and 41C on the SX600-G and SX500-LG respectively) and is equipped with slower fan due to lower 300W max. power.

I think we have a part in this too. After High Power showed that prototype in 2013, no one wanted to buy it for a year (because no case was built specifically for it). When we approached them and confirmed our order and commitment to support it with our case products, that is when they were able to get Chieftec and others on board. We should have been the first to market with it had we not held back and worked on making it quieter.
Thanks for being brave enough to jump into the clickety-clack racket here. It's not just some of us guys tho...check the straw poll - it's 45% of your customers. If you consider that number 'some', well...can't help you with your math skillz. Only 18% of those voting would be considered happy with the SX500-LG's fan. Or lucky.
I want to believe that you guys spent 3 solid months evaluating the best quiet fan options. That you selected a fan with obvious defects - poor undervolting behavior, sleeve bearings, strange controller profile and sloppy QA tells me Silverstone needs to expand testing with quieter spaces and more attention to detail (I wonder where you find keen-eared testers...). Or it says the BOM speaks louder than the fan.
I don't want to flame you or deride Silverstone - I truly appreciate the difficulty of smushing all that power into a small space. I want you to succeed. It's just so frustrating to see this latest attempt to be at best, below average.
The SX500-LG was #1 on my list for next month's new build. It's no longer even in the top ten. Please tell your management team that there are some of us (probably most of us) who would happily be Silverstone SX500-LG customers even if it cost a little more if it had a quiet fan with decent bearings, quality control and a reasonable controller profile. Tell them quietly. If they can't hear it, then we can try another approach.
I want to at least jump in here and say that Silverstone is pretty much my only option for a 500W+ SFX(L) power supply. For that alone I'm appreciative. I held off on the SX600-G only because I knew the SX500-LG was coming out with an emphasized effort on reducing noise. Had the SX500 not been released, I would've had to live with the noise from the SX600 - but even so, without it, my build would not be possible.
That said, my SX500 unit is flawless so far. I've only had it for a week, and I know some people claim the galloping noise can start at any time - but so far so good. I doubt I'd be able to hear it over my GPU blower anyway.
Often times the loudest voices are the ones most dissatisfied, which is certainly the case here. So I just wanted throw in at least one positive comment around here. Thanks for communicating directly to your consumers.

I don't have this power supply, and while it's too bad it isn't perfect, it does still seem to be the best option for my needs so I will be getting one when I can find one in stock.
So while there is obviously still room for improvement, I am glad Silverstone is investing in SFF and hope they see success with this product so it is worthwhile for them to continue pushing SFF forward.

I think it's good that you tried, although the bar is being set high
Many reactions I've read here and on other forums, customers seem to presume it would be an easy matter to source a "better" fan. But I'd like to ask was that possible for Silverstone to do?
Can you explain better or be more transparent about the process of selecting the Globe fan in the SX500-LG? And I'm also curious how your engineers came to choose the Adda fan in the SX600-G.
I've yet to see a good suggestion for an alternative fan that fits the electrical profile and has the correct airflow curve for either of these PSUs.
(Oh, and make a platinum fanless SFX model! C'mon Tony... just make it already otherwise we'll start a Massdrop to get Seasonic to make it ... just kidding
)Since swapping my 450W SFX for this SFX-L im having occasional problems with fuses going out.
In two weeks time the fuse have gone out four times and im still trying to figure out why.
Usually it goes during the night when the computer is off but today it happend when flicking the button on the extension socket that the computer is hookedup to.
Im using this:
http://www.brennenstuhl.com/en-DE/m...-h05vv-f3g1-5-1-permanent-4-switchable-3.html
Any ideas what could be causing this?
Ive only got the computer with display and a laptop power brick that powers my server hooked up to this extension socket.

What other appliances do you have on the same circuit (not just the socket)? Eg, what else goes out when the breaker trips? If the computer is off and there is nothing else causing an overload you have a short/ground fault. Could be caused by bad wiring, leaking water, etc.
The fan looks like its the same one as the cooler master xtraflo 120 slim/akasa/ID cooling s1201512, with a "globefan" sticker and 2 wires instead of 4.
well

Can you post a pic of the globe fan without the sticker please? I'm curious to see if it's using a different motor to achieve lower start voltage.
And also, does the fan make the same galloping sound outside the psu?
There are hardly no other appliances at all.
At first I thought it was the freezer but ive moved that to a socked on a different circuit breaker.
Basicly its the computer, microserver, display, router and a desk lamp that is using that circuit breaker. Same circuit breaker also caters for a couple of other wall sockets but nothing attached to them.
The circuit breaker has been activated three times during the night when nothing but the router been on. But today it broke the circuit when I pressed the button on the extension socket.
4+1 extension socket (4 button controlled + 1 Always on):
Button controlled appliances - computer, server, display
Always on socket - router, desk lamp.
Maybe its a dodgy extension socket since the cicuit breaker cut power when nothing but the router was on but also today when I pressed the button controlling its other four sockets. It seems to work fine for long periods, its working fine as type this and it has never cut out on me while using the computer either during the night when its not in use or when press the extension socket button. I guess that would indicate its not the PSU, since its been breaking the Circuit even when the computers socket been switched off?

I used this fan (ID-cooling brand) for several months on an H55 radiator. It was not making any galloping sound and it was fairly quiet at less than 1200rpm. My system was not "silent" per se but I think I would've heard a galloping sound... It may be the PSU components getting too close to fan blades and causing an rhythmic irregularity in air flow / air pressure. It may be just bad batch of fans too...
@fusionxr: nice find, yes mine looks exactly the same as the one in your pictures, other than the wires and stickers
imgur.com/kB899z8
if i spin the fan manually with my fingers, yes i can hear a brushing sound. it's definitely from the bearing.
interesting thing is that the sound becomes worse at certain angles. for my fan, if i orient it vertically so that, when looking at the side without the stickers, the wires come out the bottom of the left edge, the brushing sound disappears!!!
in that orientation the motor is actually really quiet when i spin it with my finger.

Don't feel too bad, you could come out with a Titanium rated fanless 750W SFX with not even the slightest hint of coil whine and we'd still find something to complain about
I personally find the clacking noise a bit annoying but I also realize there are very few options for slim 120mm fans so I don't think that there currently exists a suitable fan that would satisfy everyone here.
Below is this fan's performance specification for those interested:
Dimension: 120mm x 120mm x 15mm
Operating voltage range: 3.8V ~ 13.8V
Power consumption: 2.76W ~ 3.36W
Rated current: 0.23A ~ 0.28A
Max. speed: 1800rpm
Airflow: 63.8CFM
Air pressure: 1.7mm H2O
Rated noise: 31dBA
Weight: 115g
We'd also be interested in knowing if there is a better fan than this with an even higher performance in the same size.

ID-Cooling seems to have updated their fan with a new frame. Their specs a bit lower but comparable. It may lead to lower noise though: http://www.idcooling.com/Product/detail/id/29/name/NO-12015
How about your own FN123, Tony? It looks quite good with nice specs... Or, rather FW121 since it's PWM?

Thanks for the specs Tony!
Starting voltage is too high, 7V. Common problem with PWM-only designs, they're meant to be controlled with PWM and don't handle low voltages well.

Yeah, alright, but I still think their own FW121 looks nice visually and specs-wise
http://www.silverstonetek.com/product.php?pid=500
Yeah, we've tried our own FW121 too, unfortunately its was too efficient in that it couldn't stop spinning even when voltage was dropped below 3.5V (despite its starting 5V rating). So it wasn't a feasible option for semi-fanless operation that we wanted on the SX500-LG.

Don't get me wrong, but I'm not sure if anyone really cares about semi-fanless operation. I mean, who cares if the fan is spinning at 300rpm? What matters, and what almost everyone here seems to care about is not the idle performance and db, but rather the load performance and db. That and irregular noises (galloping, etc.)
Thanks for your response btw.
+1000
Honestly, had Silverstone not made this PSU semi-fanless at all, no one would be complaining I bet. The fan is practically dead silent while spinning at load, but from my experience once the rpm gets low the clicking just takes over (especially if the fan constantly starts/stops/starts/stops/etc.).
Unfortunately I've since went back to an ATX PSU, but still look forward to some ver.2. As I mentioned pages ago, the PSU is solid and quiet at load, my issues were just with idle/low rpm fan db (though never with performance).

Well, yeah, we do certainly care about those irregular noises in any shape or form, regardless of the rpm. I think the remedy is to use a good fan with high quality motor and high build quality in frame and blades.
That's especially why I think FW121 would be a great candidate as it does look to have a good quality build...
Still trying to catch up on previous posts, but if changing the fan out with something like that turns out to be really simple to do I'll be kicking myself for returning.
