you can try purchasing a fan controller or you really want to get fancy, try entering the system bios and see if there are any options there, you can also try downloading speedfan @ http://www.almico.com/speedfan.php it kind of depends if you have a 3pin fan connector or a 4pin molex, the bios controller and software will only work if it is plugged in via 3pin, if its a molex, the fan is sure to run full speed all the time unless it has a 3pin connector with a single cable (control channel).
