The board was Ryzen 3000 ready out of the box, so I don't know how many more BIOS updates are available, and even if they are, I don't see how that will bypass the 3-pin limitation. In addition, the manual advertises that the board has the 'Fantastic' option available in the BIOS. How much more could it possibly cost them to put on a 4-pin PWM connector as opposed to a 3-pin? Yes, I am aware that this is somewhat of an entry-level motherboard, but the manual or website make absolutely no mention of this, whatsoever. The 'chassis fan 2' is a lowly 3-pin connector, so it stays on at 100%, regardless.ĭoes Asrock really expect people who build their own machine to only use one case fan?! This is absolutely ridiculous to me. Here we are, eight years later, and Asrock still hasn't figured out that people have more than one case fan? The 'CPU fan' and 'chassis fan 1' are 4 pin connectors, meaning they can be controlled.

(and quieter) In addition, only one of the chassis fans was able to have its RPMs controlled. This meant that your CPU fan would spin at 100% (loud AF) trying to keep the CPU at 65 when there is nothing wrong with it running hotter than that. On the old rig, the maximum target CPU temperature was 65 degrees, no matter what. I upgraded from an Asrock H77M that had the same issue, and worse. I just built a new machine with an Asrock B450M-HDV motherboard.
