Pros: This unit does exactly what I wanted without having to purchase several products to do the same thing.
Cons: The temp sensors didn't last very long as they are very fragile and the sticky tape on the end of the sensors isn't very sticky. The power module that has to be plugged into the standalone "USB" outlet was kind of a pain to deal with, especially if you move your computer around a lot. I ended up ...
Summary: One guy wrote a review on here complaining that the multi function knob on his unit was broken, before one of you think that yourselves, you have to push the knob in for aprox. 3 sec. before it flashes and lets you switch control between the different fans/temp probes you have plugged in.
Pros: It looks really good, the quality is right where it should be.
Cons: The fans you use have to be 3 wire, variable speed. I did not know this when I purchased it, all my case fans are 2 wire...... fffffffffff. If you plug in a 2 wire fan, it will turn on and off every few seconds(odd).
Summary: Nice appearance. Like most Zalman products they look cool and draw the inexperienced builders but they lack solid engineering and inferior quality components. I am a system builder and will only utilize their product if it is demanded by my client.
Pros: Nice appearance - they look cool, but that's about it.
Cons: No power connector included, missing parts Poor instructions Cheap connectors, poor tolerances. Poor live tech support - decent web support
Pros: I had an MFC2, and it definitely had a few flaws, all of which seem to be resolved in the MFC3. Seems to have unusually good algorithms for keeping fan speeds steady, even if you're trying to run them so low the fans almost refuse to start up. This comes with temperature probes, but the fan speed...
Cons: If you want the speed of your fans to be controlled by temperature, you need to buy actual temperature-controlled fans, or hook fixed-speed fans to the motherboard for control. This controller will just not let you couple temperature and speed.
Summary: For my setup, it works well as I only need to adjust the speeds on the GPUs, see power consumption, and monitor temperatures. There may be issues surrounding controlling CPU fans, but for my purposes it's great.
Pros: -Power usage display a big plus -Can control speeds of fans - been very useful when certain games causge my GPUs to heat up allowing me to crank up the GPU coolers -Viewable from all angles
Cons: -When connecting a 3-pin fan to the PWM spot on the back, you lose the ability to control the fan speed (expected, I guess, but a little annoying) -Might just be my experience, but the cable provided to connect to the MoBo's CPU fan connector also does not allow speed adjustment.
Summary: The Good: Looks nice on my twelve hundred. Fan control is good. The power watt indicator is a nice addition. At least I know my 850W PSU is just right for my sli gtx 260. FYI, the power tops 430W only. So I can go 3SLI =)
