There is a free program called RivaTuner v2.24c download from Guru3D.com that allows manual control of the fan.
I am worried that you may have more then some fan problem. It seams offul strange that you would have to have the fan changed only after 6 months. Is the unit getting enough air flow through it as it sits? If the inlet is being blocked like sitting on a carpet or something that would also cause the fan to over drive to keep it cool.
