Heating up- the fans are at 999 and freezes

Text:

Hi, I have Macbook pro 1,1 A1150.. 2GHZ [Up to Dated SMC and firmware] The system fans never kicks in, It seems that they stay at 999 rpm even with high CPU usage and it is burning hot.. I ran Apple Hardware Test and all test are passed.... When I ran the temperature software it shows the temperature of CPU idle 50+C and the Fan is 999 RPM.. I even installed iCyclone to control the temperature it does a good job but only if you are inside OS. If i get in to Single user mode or watch Youtub it almost burning and freezes ... I did a SMC and PRM reset.And a clean install of 10.5.4 still the same problems. Plz help me what is wrong with this stupid mac bookCON....i m new to mac and i was not expecting that mac would be like this.. Thanks
