(Is power enought or it will burn?) AeroCool Modern-V fan controler with 8 fans on CoolerMaster HAF X

I have CoolerMaster HAF X case, and I added few more fans to it, for a better cooling. Here they are, total of 8.

2x230mm - 0.40A @ 700RPM (19 dBA)
2x200mm - 0.28A @ 700RPM (19 dBA)
2x140mm - 0.14A @ 1000RPM (19 dBA)
2x120mm - 0.15A @ 120RPM (19 dBA)

They all are 3pin connectors, so I used adapter 3pin to 4pin mulex (12). I connected them directly to 1 of the power supple 12v lines (I have 1200W PSU Antec) and they run at full speed and the noise is pretty annoying for my likings. So I decided to slow them down to minimize the noise, and I have been looking for LCD fan controller that can do the job.

I like this one: AeroCool Modern-V http://www.aerocool.us/peripheral/modernv.htm

It takes 1 4pin mulex connector, and gives you 4 3pin fan headers. Since I have 4 pairs of 2-exact same fans, I plan to use Y splitter in order to control 2 identical fans with 1 headers. However in the manual of the this controller it says that can support 0.5A / 6W per header. Manual - http://www.aerocool.us/images/peripheral/Modern-V/Modern-V-manual.jpg

So, theoretically if all fans are running at full speed (not planing to), then the 2x200mm fans will be barely over the limit, and the 2x230mm fans are like 65% more.

2x230mm - 0.40A = 0.80A X 12V = 9.60W
2x200mm - 0.28A = 0.56A X 12V = 6.72W

All that said, I did tried it and plunged both 230mm fans to 1 header and it works, it does the job although the specifications say it is not supported. Since the other 2 headers are not pushed to the limit (barely used), does that give the device some headroom? Can I keep using it like that or it will eventually burn out? Will the fans maybe burn out? Keep in mind that 230mm fan uses 0.40A at full load @700RPM, and I am running them like 400-600RPM. Since the controller is lowering the Amps given to the fans, does that make it OK  to provide enough for both 230mm fans for example? Thanks and sorry for the link question, just wanted to explain myself better.

All their fan controllers use same power requirements, and haven't found any other one that can do the job better. Don't like knobs sticking out of  my case aether. Any suggestions please! Thanks

It should work, If not plug the biggest draw fans directly into the mobo and use the fan controller in the Bios to control them. I Have the aerocool touch myself 

I have an older motherboard (Intel D 975 XBX) which does support 2 3A and 2 1.5A fan headers, but haven't noticed any fan regulations in the BIOS. I will try and look, thanks for the suggestion. So, there should not be any issues of burning the fans or the controller this way?

as long as you keep it below the specs of the controller then your good. the fan control in the boise is usually under the system monitoring tab, then fan speeds 

Yes I hooked up 1 fan directly into to mobo, I looked at BIOS and it shows true speed, that runs at 700RPM max. However I'm unable to change the speed of the fan, in the BIOS there is no way to do so. Is there a work around? I tried software "SpeedFan" which corectly detects the fan and the speed, but not sure how if at all I can change it to like 550-600RPM

It looks to be under Boot Configuration Menu and It looks the be the last option that you can change. 

No such thing. Under BOOT configuration there is only which device to boot friest (/hdd, CD-ROM, floppy, network and ect...). You must be mistaken! :(

humm its but have been the wrong board i was looking at on intels site
