For silent computing, most PC products are bad. Most are noisy or too hot.
-- Think about how many HDDs can really be considered GOOD. Only the Barracuda in my opin.
-- How many fans -- a small handful, and NONE at 12V.
-- How about PSUs -- a few.
-- CPUs? -- probably one: C3, maybe the slowest Cel/P3 currently available.
-- HSF? -- Just a handful if used as intended by the mfg.
Do you see what I am getting at? If the site tried to say what is NOT quiet as well as what is, well, the amount of stuff to wade through -- for me, for you -- would be a hundred times more. The site is useful for people like you because try to examine products that are useful for quiet computing -- because I don't
write indiscriminately about every doohickey that comes my way.
Sometimes, I've reviewed stuff I didn't really want to -- the Vantec PSU, for example. I knew before I ever saw/heard it that it COULD not be quiet. It got kind of forced on me. I would rather spend my precious time examining and writing about products that are useful, not one that is noisy.
Having said all that, I agree that giving honest assessments of bad products is part and parcel of reviewing. We all know that false advertising is already happening with so-called quiet PC components. I've alluded to that in the recent editorial piece about the state of PC Noise.
This Nexus fan controller may be an example of that. I was hoping it would be a good product. If I had received a sample & found it to be nasty, well, I would have told you all about it. I think you all know I don't mince my words much.
The good thing is that YOU guys already know it's not that great, that it buzzes. So I don't have to get a sample from whoever, and then have that supplier feel burned by the first review of the first sample they send to SPCR. We are not Anandtech or Tom's Hardware, we don't have nearly a decade of history through the greatest tech growth period in recent history, and we don't have a hundred advertisers and sponsors -- quiet computing is still just one small current in a big river.
Like I said, I would prefer to help you find what is good, not warn you against what is bad. I have gone out of my way to do the latter from time to time & will do so in the future again, but this time you've done it for yourselves already. Which is great. Caveat emptor always applies in our world.
That's a longwinded way of saying I choose your option 4).
