Is anybody using the Zephyrus fan controller? Sounds like a very advanced unit, able to control fan speeds, lights, etc. The nice part is you don't need an open front bay for the thing....and the control is 100% software.

The website lists a new set of drivers...the first version was apparently buggy. Very inexpensive for such a device.

I bought one 2 months ago, installed it with their earlier version of drivers and control software (version 1.0.0.2)- it didn't work properly, even with many correspondents with their tech support issues were not solved. So I took it out and use manual control instead. I have posted my bitter experiences in some threads here during that time.

With their new software (they updated that 2-3 times since my purchase), I decided to reinstall it last Friday with the most updated software (version 2.0.1.2 I think) and have been playing with it for a few days now.

Zephyrus now control 3 fans in my system. 120mm Globe intake installed on the birdhouse duct(thanks to you Bluefront, the birdhouse works pretty well), another 120mm Globe exhaust fan, and finally an enermax 80mm fan that come with its own variable resitor which I swapped in as my only psu fan with air duct. (Here's are details of my psu air duct - for those who may be interested). I leave my CNPS7000A fan with fanmate at minimum.

My impression so far are the following:
1. The new version of software has vastly improved from the original one. Its improved reliability raises my confidence level in Zyphyrus from 30-40% level to say 85%. Software still hang sometimes.

2. Software can be further improved (and must be improved) before users can use Zephyrus as intended i.e. automatic fan control which for me means user's supervision should not be constantly needed.

3. My wish list on the improvement include possibility for user to set how fan ramp up (as of now it will scale the fan speed up on its own depend on the temp setting you set and will reach 100% duty cycle quite quick - this is not a totally bad thing though but user (me) would like to play with my toy too . And may be to have 5 temp sensors instead of 3.

4. On a positive side, as you said this is an internal unit and quite small so it doesn't make case clutter. It can control 5 fans which for SPCR-addicted this should be enough . It comes ready with 3 analog temp sensor, which is a big plus for me - I put them on VGA (back side of card), CPU(next to P4 heat spreader), and on PSU heatsink. Another plus is since control program will load after window - all fans will start at 100% duty cycle. And probably also reasonable pricing is a plus. Regular software update can also be considered as a positive sign, although quality of software is not there yet, I'll give them a benefit of the doubt for now.

Having played with it the last few days I found that in fact I can turn off the exhaust fan during non-gaming period (I also use ATI Tools to underclock core clock to about 60% under that condition) without significantly raise internal case and key components temp. Anyway, I'm still playing with various settings and taking note on temp. along the way. Will post some results later..if that's of any interest .

Whew......too long post I think.

Wow...thanks for the info. On paper this thing sounds great. I hope they get the software worked out. Please post about your experience with the new drivers.

Geez...I was set to buy one.

Zephyrus software reminds me of ATI in the old day when ATI drivers were so buggy which made their VGA card awful. Once that was fixed ATI cards have been among the top performers ever since.

V.L.System is suffering by similar fate, as their other flagship product (LIS display unit) also lag on the software side. The owner (CEO) seems to involve a lot with Overclockers.co.kr in Korea - if not a founder himself. That might explain primary focus on hardware.

I might sound a bit negative in my earlier post, but at this point I'm happy with it enough to keep it installed (obviously since I've already paid for it ). Would I recommend people to buy it now? No...at least not until some more software updates are made. Hope that would not be too long as I think they are moving in the right direction.
