Erm, except for when you have like four 120mm fans in your case or bigger size. I think gauging your case temperature solely off of PSU temperature or even load is largely fallacious.
Fans have moving parts. Having your fan die or become noisy isn't in anyway related to the life of your PSU unless your fan dies completely and it's sat like that for ages while under extreme load inside a sauna. That's like saying your processor is probably going to die because your heatsink fan went bad... or video card. I've replaced the fans in my case four times, that doesn't mean the case is going bad. They're completely unrelated.
How is a fan dying in a PSU where it is removable different from a fan dying in a PSU where it isn't? They're both dead and both the manufacturers problems. To prevent someone from running the PSU fanless they could simply look for a RPM signal and shut off the PSU if it stops or make it beep or something. They could also simply have a overheat sensor for the PSU (which some have anyway). So if it works in a fanless setting without triggering any warnings, why would it matter? There are many ways for dealing with that.
I never said I knew it was 42db loud before buying it. I said it was listed as whisper quiet and that's why I bought it only to find out it reved up to 42db.
The 12cm ball bearing fan provides superior cooling performance to dissipate heat in the power supply enclosure while running whisper-quiet. Intelligent thermal control balances noise and cooling. Soft-mount rubber cushions reduce fan rotation and vibration noise. Plus, the universal ventilation (honeycomb structure) minimizes airflow resistance for maximum cooling efficiency.
I'm pretty sure if something is falsely advertised there is plenty of reason to be upset, completely putting aside that me making this post was to engage in a intelligent conversation for offering ideas to PSU manufacturers (namely a superior method of PWM control based off temperature and interchangeable fans). You can take your 'umad' BS somewhere else, it's not conducive to intellectual conversations.
Run furmark and prime95 at the same time and then stop back here. There wasn't an exact review from hardware websites for the model of PSU I was looking at buying, I checked. A handful of other reviews on the Newegg website also mention the noise issues. While a 8350 consumes more juice then Intel parts I'm sure most people are using, I don't believe it would be enough to make the PSU that much louder then someone who is also using Intel parts. GW2 easily made it spin up to full speed after about 5-10 minutes. I have a 7870 and a FX8350 for a hardware comparison.
That was the other PSU I was looking at though and on the Seasonic website they're both listed as having "S2FC" fan control so I assumed they both used the same algorithm. I ended up going with Corsair, specifically this model:http://www.newegg.com/Product/Product.a ... 6817139005
Looking back at that review I really should've gave it two eggs because of this. While it doesn't matter for some people it made me send it back as it was intolerable.
