I'm having a real hard time to control 5-6 PWM fans something like this PWM Fan Hub : Wind Rider http://www.coolermaster.tw/products/product.php?language=en&act=detail&tbcate=65&id=2521 anywhere to buy this or something similar?
According to the Cooler Master website, ARC Computers are an Australian dealer for Cooler Master products. They don't list it on their site but you could contact them to see if they could get one for you: http://www.arc.com.au/ Alternatively, you could try emailing Yoyotech here int he UK to see if they would ship one to Australia for you: http://www.yoyotech.co.uk/item-detail.php?products_id=8994.
get a couple of akasa PWM fan splitter cables. you can control 3 PWM fans from 1 PWM plug and they have a seperate molex power connector to run them, so there's no fear of popping the mobo's fan mosfet. chain as many as you like together and have them all running from your CPU PWM plug for complete automatic control of every fan.
This ^ is a good idea. Another option is too make one yourself... http://forums.overclockers.com.au/showthread.php?t=899162
