Are there are any other major disadvantages to the Asrock b85m-itx, other than fan control? Would it not have some sort of intelligent fan control in the BIOS? If not, would it be possible to use Speedfan with that motherboard to dynamically control case and CPU fans?
I know very little on AsRock, i done a couple of builds for friends in the past, but they were not silent seekers, so never even bothered with bios fan control, they always use their fans at 12V. My experience with other motherboards in bios isnt that great either, Asus didnt allow me drop my Noiseblockers PLPS below 950rpm in both GENE IV n GENE VI (with fanXpert2 i can go to 650rpms), on my supermicro server board..... it was a mess, on paper was ubber, like intel motherboards it could drop scythe fans to its lowest, but the joy only lasted 10sec, suddenly the fans ramp up to 1600rpm, and then down to 300rpm and endless loop, like if it was breathing but very loud.... it was more an issue with supermicro bios that as soon as it saw them dropping low it panic and increase the voltage to 12v and so on, i msg supermicro and they offer a fix on a future bios that i just couldnt wait, so went with quiet 3pin fans. On Intel i have very good experience, their bios while not that tweakable, they can drop scythe fans like slisptream and kamaflex2 pwm fans to their lowest (250 to 300rpm on pure bios), you can check my htpcmi build where i use 5x kamaflex2 and have them running at 300rpm.
Now speedfan, i never been very keen on it, some motherboards work great but in some.... a sensor it not recognized... and had bad experiences that i never could do it the way i wanted, then again im not very patient on noise, so it either works or not.... so if you have good experiences and know that asrock sensor will be recognized on the latest speedfan version and that you will be able to control the 3pin fans on the Q08, then go for it. I just like more knowing that ill be able to control my fans with fanXpert2, the motherboard that i linked i believe only comes with fanxpert, not sure though, not that many info out about it, but on my GENE VI im really happy, it can control my 3pin case fan to 430rpm where its inaudible and the 4pin fans (noiseblockers PLPS) to 650rpm, where no bios was able to drop it.
Either way im not trying to make you spend more money, if you are very knowledge on Speedfan and know that you will be able to control the fans, go for it.
