i just got the black version last night and am still on the fence.
First off, mounting was a nightmare. I've got a Chenbro case that only lets me mount with rails (another pain in the ***... different issue though). The aerogate's pre-drilled holes don't match up with the standard mounting holes in my case, so for right now, the face of the aerogate is sitting a little shallow. I'll have to drill an extra hole to get it to be flush with the CD drives...
Second, documentation sucks. Not just sucks... SUCKS. The fan connectors are labeled and are easy to figure out, but the thermal sensors (yes, comes with 4 diodes). Their idea was to match up a thermal diode with each fan sensor, but the only way to match up the correct sensor to the fan controller is 100% inference. I got it by trial and error by holding the sensor in my hand and cycling through the display to see which temp was rising.
BUT... all that aside it looks awesome, and once the above barriers were worked out it's extremely functional. Once everything is set up, you basically hit one of 4 buttons and get the temp and fan speed for that 'group'. you can turn the fan speed up or down to tweak the temp (if your fan rpms are variable). Has an audible alarm if the temp gets too high, but I haven't figured out the threshhold at which it gets tripped.
Note that there's really only 3 fan controllers - one is used for the onboard 40mm fan, although that fan could easily be hardwired and another fan monitored in it's place.
Overall I'm happy with it, but do NOT think it's worth the $50 you pay for it. Should be a $25-$30 device.
BTW - the only place I could find that sells the black version was
www.sundialmicro.com. Apparently the black version was just released on jan 8th, and not many vendors have it.
