that is a low profile low speed low performance gt730 that should perform like a gt210, horrible, that is why you have a diminute fan doing noise all the time, you are asking too much form it
this is a gpu made not for more than watching movies, with headphones
this one exists also without the fan, if you bought it, if you can return it, i would do that
the fan can't be controlled because surely is not a pwm fan, so it just spins, controlled by the gpu but gpu temp sensor, not a module you can control
if you can change it, change it for that same gt 730 but the one with fast gpu, fast ram bus and a real heatsink and a fan, or get a cheap r7 250, what i have atm, a big fan and big heatsink does make a difference
