Power Supply Corsair SF600 - 600W SFX PSU

Ah I already suspected the case had a direct intake for the PSU like that, it makes sense that it can keep its fan off for longer. Very cool!
That might have to do with the orientation of the PSU. We don't know where the temperature sensor is, but it could very well be directly in the air stream of the hot passive exhaust.

I've run some further tests and the fan PSU has remained off in all tests. I have been using the corsair SF450 model, so I don't know if this unit runs cooler than the SF600 at equivalent loads.
I also think that the 140mm thermaltake fan in this case may be having a cooling effect on the PSU, the power supply is mounted a few mm below the top of the case so there is a small gap allowing air to escape around the PSU and out the top vent. This may be helping to 'drag' the hot PSU air out the top.
First of all I ran the Unigine Valley test for 30 minutes, the SF450 fan did not start up at any point.
Second I loaded up the game Dying Light, left it running for 1 hour, again the fan did not start up, the processor was under 40% load during this test.
Thirdly I ran Unigine Valley simultaneously with Prime95 for an hour loading both the GPU and Processor 100%, the fan remained off.
The vents on the back of the SF450 do feel fairly warm (but not hot) after all this testing.

Thanks! I'm still wanting to get better equipment, but in the meantime I'm trying to offer information that you don't typically see in other reviews like the fan controller behavior.
Just completed another build with the Corsair SF450, this time in a Silverstone FTZ01B. The components used were:
- Silverstone FTZ01B
- Corsair SF450 PSU
- Gigabyte Z170N
- Intel i7-6700
- Noctua NH-L9i
- 16Gb Corsair Vengeance LPX
- GTX 970 SC 4Gb EVGA
- 256Gb Samsung PM951 NVMe SSD
- 1Tb 2.5" HDD
- UJ267 Bluray Drive
- Windows 10
I carried out some testing to see how well the SF450 coped whilst under full load from the I7-6700 and GTX 970, I don't have any noise or power measurement equipment so my results are just basic observations!
Throughout this testing the FTZ01B chassis was positioned vertically. Under normal usage for a few hours setting up the OS the SF450 fan did not spin up and remained silent.
The first stress test I carried out was Unigine Valley, fired this up on maximum settings at 1080p and after around half an hour the SF450 fan was still stationary.
As the Unigine test does not stress the CPU I then started Prime95 with 6 threads running. After around 10 minutes of this I noticed that the SF450 fan started spinning very slowly, it then turned off after around 20 seconds. This cycle repeated each time the fan staying on for slightly longer until it remained on constantly after about half an hour of Unigine + Prime95.
The fan speed was very low and could not be heard over the GTX 970 fans, even with my ear next to the SF450 intake grill I could not pick out the PSU fan over the other fans inside the case, it was by far the quietest component in the case.
By the end of the test the GTX 970 was sitting at around 74C, the CPU was sitting at about 63C and the system temperature was about 41C.
Overall I am very happy with the SF450 for this level of build, I will definitely be using these power supplies going forward in place of the Silverstone SX500G which I have used up until now.

Not that I could hear, the only time the PSU fan span up was when the CPU and GPU were under full load, at which point you couldn't hear the PSU over the GPU fans

Still waiting for this to launch in China. An SF600 showed up on Taobao for the first time yesterday......but they're asking about $160 for it 
I order an E-W150 for a ITX NAS case and should arrive Friday. I may grab another ST30SF for the power supply on that

In the UK the Corsair SF600 costs £100 and the SF450 costs £70, but the Silverstone ST30SF costs £42. It doesn't look like Corsair want to compete (yet) in the sub 400W SFX PSU sector. Besides, 300W for a NAS is surely enough power? The ST30SF is a great power supply as it spends most of its time running silent.
The ST30SF is great but I will be powering 6 hard drives in a 7L case, I'd prefer to use modular cables to get rid of the ones I don't need. I'd *like* to have an SF450 but ST30SF will work.

Tom's Hardware also included the SF450 in it's "Best PSUs" list for 04/2016:

Already have two of 'em chugging away in my home PCs.
