    Yea I definitely noticed that when I upgraded the CM fans in my case to GT AP-15's for the side panel and barely saw a temp difference. After a google search, CM said that anyone who bought a Cosmos II is eligible for a fan controller upgrade so hopefully that fixes it since having the fans on my video cards at 40% idle can get annoying after a while.

    No, my issue with the fan controller was the noise you hear from the fan here.

    Yes. I have the very same fans in my 600T right now, without any noise similar to it, despite running undervolted. -.-
    (I'm guessing around 1k RPM, I'm not sure how far down the resistor takes them.)

    Yeah that would bug me, is it obnoxiously loud even when they are in the case?

    Makes me wonder if any fan manufacturers could make those fans that Apple made for the new MBP...

    Err... what? The fans are very quiet. If I didn't have a nasty whining noise from the pump I could almost forget the PC is on entirely.

    I thought you were talking about a loud ticking. :P That's from the fan, yes?

    While the sound is definitely from the fan, the noise is caused by my brother's Cosmos II case when I tested it with that fan controller.

    You mean standard radial fans but with a new fancy name on them?

    I think he means the whole "unsynchronized blades" thing. Where the blades are intentionally not identical across the board.

    Oh, that. Meh, it's not new either. I mean, consider how incredibly small the computer cooling business is in the great scope of things with industrial cooling et c, only a small trickle finds its way to computers, since most aren't considered worthwile in the computer systems.

    What does unsynchronised fans do that regular even fans do not? Off the top of my head, I'd say it causes an uneven noiselevel being more pleasant to the ear.
    The problem with that, I should think, is that it'd only work with radial fans, which themselves are already loud, and not really something one would want in their computer build.
    I'm looking forward to Noctua's active noise cancellation fan technique.
    It is extremely silly, but it works.

    ^This. I've at least not seen them before, so again tetris, no need for condescending tone. =/

    hmm, surely they could apply the same technique to the non-radial fans we have in our cases?

    Forgive me for not knowing the scientific terms. ;p

    You mean like having non-straight blades? Twisted, indents, polished ends? They are.

    Having every other blade differently angled? It would reduce airflow potential and change the static pressure in an undesirable (inconsistent) way. Without reducing noise levels.

    Either way, this is post your gaming setup-thread, and not Jeopardy! Special Fan edition. Let's move this venue to the chat thread?

    I tried playing with all the settings in game but not avail. Got it running nicely using RadeonPro and some manual fixes, thanks.

    I swapped out all nine AP-14s in my PC for Kama Flow 2s because Gentle Typhoons just aren't any good for pure airflow. I don't even use them on my low-FPI radiators because they hum noticeably at 500-1300RPM, especially when there's several of them. Kama Flow 2s have a starting voltage of 3V, are very quiet at low RPM, and a little louder than GTs at max RPM. I did have to replace one after it developed a tick...seems like an isolated incident.

    For video cards, you could use MSI Afterburner's fan controller to keep those fans around 20% until the GPU core hits 50C or so. I used the curve below.

    A fan controller which uses voltage control isn't to blame for a ticking fan. A lot of fans tick at specific RPM, especially sleeve bearing fans like the new Corsairs. When I buy new fans I purchase several different types, figure out which one works best for me and return the rest to Micro Center / Fry's / etc.

    This is also why I continue to suggest Asus motherboards regardless of how much cheaper ASRock's options are. Asus's Fan XPert 2 utility is better than most external fan controllers for the vast majority of users. It's better than just about anything other than an mCubed BigNG T-Balancer.

    While absolutely true, this doesn't change the fact that the Cosmos II's fan controller is in fact the culprit. Cyanotical experienced the exact same issue with his GT fans, as have others across the internet, where they've tested the exact same fans with other fan controllers or such afterwards and found the noise to vanish.

    And this review does actually go ahead and strip away the fancy buttons to see what's actually underneath.
    The rectangular chip is the brains of the operation, unfortunately it has absolutely no markings, so I have no idea what sort of brain it is. The control setup is quite interesting in that it is neither straight PWM nor a buck controller type voltage regulator (note the lack of inductors; no inductor, no buck regulator). In the interest of figuring out what method it does use I hooked my oscilloscope up to the output with a fan hooked up as a load, the following picture is a graph of the voltage delivered to the fan, each line vertically is two volts and each line horizontally is 10 milliseconds.

    For starters we see that this is pulsing the voltage at a very low frequency, around 14 Hz or so. Beyond that it looks like the control chip feeds some voltage to a transistor that fills a capacitor and that capacitor in turn feeds voltage and current to a second transistor that controls the fan itself, as the capacitor drains out the second transistor lets less current/voltage through and the fan doesn’t get as much. It’s a rather interesting method and much cheaper to design and build than a buck regulator, while still capable of delivering the full 12 V when set to full, unlike a linear regulator setup.

    The only real issue with this setup is that some fans will make a noise every time the voltage pulses. When set to full speed the controller doesn’t pulse the output voltage, so of course the noise goes away entirely. Both medium and low speeds require the voltage to be pulsed and hence can cause fans to make noise. Of the included fans only the rear fan makes noise; the top fan, the front fan and the two lower HDD bay fans make no noise on medium or low speed settings beyond airflow noise.

    Other than that noise from the rear fans, all the fans are very quiet on low, and still quite quiet on medium. On high they ramp up and make more noise, but nothing offensive and no mechanical noises. Unfortunately one of the two SMD chips that are paired up for each channel is marked only with A79T, which I cannot find any data on at all. The other chip’s markings decode to a fairly standard NPN transistor with 0.2 A maximum capacity. Because I don’t know what the other chip is exactly, the above description of the fan controller is my best guess, rather than known fact.

    The fan controller is rated for a maximum of one Amp per channel, not one Amp per connector! Each channel has at least two connectors, and one of them has three connectors. Be sure to add up the power draw of the fans on each channel to avoid letting the magic smoke out of one or more parts of the fan controller; unlike the controller that comes with the Cooler Master Silent Pro Hybrid 1300w PSU there does not appear to be any over-current-protection on this controller.

    Hmm maybe I'll try them out for the GPU panel and keep the GT's for the CPU radiator but yea, they have that distinct hm which is normal for the fan. Plus I do have a fan curve but it's set a little higher than normal since the main video card idles at 65C using eyefinity
