I think your problem is it's a store bought (retail) PC. And most likely it just has the bare minimum mobo which probably doesn't have the means to let speedfan take control of those senors to adjust fan speeds. As in laptops, except for those really high end gaming laptops and that's because those laptops use all high end and high quality hardware. So even if you do figure out how to setup speed fan it wouldn't work anyway do to the low end mobo on your retail PC.
