Hi, I purchased 2 corsair af120 fans for my case, the problem is for one of them in the bios doesn't pick up any speed for it it just says zero also on hwmonitor it says the same thing, & for the other fan it shows erratic speeds it goes up to like 300000 rpm lol they spin fine but it may have faulty sensors on the fans, I've obviously tested them on the other fan ports on my motherboard (asus m5a97 evo) but it still the same, I think there's just a problem with the fans themselves because the 2 antec ones that came with my case work fine and speeds show correctly,

Anyon else had a problem like or know how to fix it, many thanks

Yeah I think I got the normal 3 pin ones, & I tried corsair link it gives the same readings so I guess it is the fans
