Replaced graphics card, now my CPU fan keeps running

Please help...

I recently diagnosed and replaced my graphics card. The repair worked flawlessly again, just like new.  However upon start up the CPU fan started running at a high speed and won't stop.  I have zapped the pram and reset the SMC a number of times.  The SMC fan app says it is not running hot, nor does it feel hot anywhere on my machine. It is running around 90 degrees fahrenheit.
