I should probably point out, too, that GTs got to their current status by having such a good noise profile relative to a given amount of static pressure in the curve, making them excellent all-purpose fans. It's partly on me since I had said around the time that S-Flexes, which were even better all-purpose fans, went out of production (and at a time when I had a high rep member's presence rather than a mod's, and when my say-so was worth a little more) that GTs were a good alternative if S-Fs were to not come back. More people picked up GTs, more people reviewed them, and it took off from there, even killing off relevance of thicker fans to some degree. I do have a small amount of regret that I didn't approach the situation differently, given my preference for turning down thicker fans over running as-fast thinner fans (my case is still loaded with San Aces and Panaflos), but it's not like it was really a bad thing. tongue.gif
That brings to mind the Scythe Kaze Maru 2 (Slip Stream 140) fan that looked to be very good but lasted about as long as a snowball in hell.

Lots of good points here. Of course the long term reliability needs to be tested and this is something I might well do since I will use a couple in my HTPC build. It's not a license from Sunon as much as getting the entire assembly but customized to Corsair's preference, but I don't know any more specifics (or can't talk about them anyway even if I did).

As for voltage control, I think most people know my preference for PWM control over it but aside from a slight issue closer to 5V wherein in upside down position I could hear the bearing move (low RPM too), I didn't hear anything else. I just did this and will mention it in the review for those interested, but again I can't say that the bearing will be fine if undervolted lower than 8V or so.

There is no external magnetic field here, I did measure for it. I don't know if an external magnetic field will affect things, but it's a non issue inside a PC.

I have decided I won't bother talking about MTBF numbers anymore, along with rated SP, airflow and noise specs. It's not like end users will use these for 50k hours of operation even.

I am curious about the pricing drop on the Noctua fans recently. It's not a coincidence that suddenly all the major retailers in the US have dropped pricing by 25-30% for the more popular/expensive models. Is this the same in other countries also?

So maglev fans are the new thing? Corsair and cooler Master now have them... Hmm...

I think I'll stick with my f12 fans at 6v for now... Basically can't hear them and I don't need a huge amount of airflow for my itx case...

Can you please link me to the Cooler Master fans with MagLev bearings? Anything to help lower prices of these, I will use biggrin.gif

@geggeg, just looked at UK prices on Nocs and they do appear to be down some. NF-A14s-redux are £12.39

Yeah, some resellers I spoke to confirmed this price drop. Interesting move. However much we may think otherwise, Corsair and Noctua are the big fan players in this market.

Can't argue with that. thumb.gif
Nocs were price quite high. I know I steered peeps to other fans because of price difference and no other reason. some of the others are not quite as good, but were so close at much lower prices it was a no-brainer to not buy Nocs.

I'm going out on a limb here and going to predict we will see some of the other popular fans lower their prices too. tongue.gif

Agreed, I have no problem recommending the better Noctua fans now at these prices. A pricing decrease is always good too biggrin.gif

Hmm, so they'd be the bearing OEM rather than the whole fan OEM. Interesting.

Also interesting, that makes these actually better than Sunons noise-wise for undervolting. Obviously you aren't recommending that anyone do it, but still good to know.

I don't know if they are just the bearing OEM or not, that's between the two entities. But there's definitely a strong Sunon influence here.
