Summary: Worked well when first installed. After a few years, expect the LEDs to start failing. Zalman seems to be suffering from quality issues, not only in this products, but others, reading from customer reviews. I'm staying away from this company for future builds until they get their act together.
Pros: Looks great and does what it advertises.
Cons: One of the knobs was a bit loose compared to the others when first received. After a few years of operation, that same knob's LED no longer lights, neither blue nor red. Tried to fix it, but it still won't light.
Summary: I may go back in one day and move the RPM wires back to the mobo so I can use 3rd party monitoring software. Having a led that changes from blue to red is kind of pointless. If the LEDS were thermal based, blue below certain temp with red indicating hotter that would be okay.
Pros: -Fits well in drive bay -Looks sexy -Adjusts fan speeds as expected -Cable length is good and Connectors are all standard -LED red/blue color changes depending on fan speed
Cons: Knobs are flimsy and feel cheap like they could easily get broken or twisted off/fail with regular use; -1 Star Out of the box 2 pins on the board for fan cable connectors were bent. Not sure how that could happen and I looked twice to make sure it wasn't used before. Gently bent back in alignmen...
Summary: The fan controller works as it should, and I actually like the LED being burned out because my case theme is white cathodes, or uv/green cathodes. blue and red LED don't work well with that. plus i thought they were to bright. I wish there was the ability to turn off the fans from the controller.
Pros: -Def a pro with the capability to control 6 fans -Black color matches my Antec 1200 perfectly -I was able to hide my HD behind the controller, to complete my custom case look.
Cons: -LEDS didn't work soon after, and then completely didn't work at all. (controls work properly still)
Summary: This thing isn't perfect, the issues are all minor ones, but they do add up. Overall, this is far better than the fan controller I had before that was priced the same, but used an LCD screen with jogging buttons.
Pros: This is the best design for fan controllers. Simple, elegant. No need to fiddle around with LCD screens, jog knobs or all the other unnecessarily complicated stuff most fan controllers have. The metal faceplate is well made and looks sharp.
Cons: Low quality design. The knobs do have a nice feel, just the right amount of rotation resistance. The problem is that the knobs wobble/wiggle. Also, the whole unit doesn't really fit well in the case, and the entire thing can wiggle. One of the LCD lights has gone out. I would be very useful if th...
Summary: Despite the negatives, the controller has turned my wind farm into something bearable when I'm not doing something CPU intensive. If they improved their build quality just a bit, I would be able to recommend without reservation.
Pros: Aluminium faceplate, does what it is supposed to do which is provide control over a multitude of fans (HAF 922 case). Using OEM Cooler Master 120mm and 200mm fans (no LEDs), no problems on startup even with 200mm fans with dial set at minimum.
Cons: As mentioned previously, unit knocks about 10% off your max fan speed. Two out of the six knobs are wobbly, one of which is extremely so - not sure how long that one will last before it possibly breaks off. Expected a little better for this amount of money.
Pros: -Connects up to 6 fans. -Looks nice. -It works.
Cons: -Had to bend the mounts a bit to get it to fit. -If your case has tool less installation than your gonna have to use screws to mount the other side otherwise it won't stay put. -Knobs feel cheap.
