It was a cautious and subdued opening from both sides with neither wanting to give the other an inch. It took 16 minutes of football before the spectators were treated to a shot, a Frazier Campbell effort from the edge of the box that was beaten away by Marteen Stekelenburg.
A goalless first half seemed to be on the cards but on the stroke of half-time the Bluebirds broke the deadlock. Young Declan John's shot fell at the feet of captain Steven Caulker, who couldn't miss from three-yards.
Whatever Felix Magath barked at his football players in the dressing room at half-time it looked to have paid dividends, with Lewis Holtby almost instantly testing David Marshall in the Cardiff goal.
The Cottagers got their just-deserves in the 59th minute, a Georgios Karagounis corner finding Hotlby unmarked in the box, who unduly tapped the ball home.
However it was not to be for Fulham. A 67th minute corner was diverted goal bound by the head of Caulker and the ball agonisingly squeezed beneath the body of Stekelenburg. When the Dutch 'keeper see's it again he'll feel he could have done better with that effort.
Just four minutes later it was game, set and match for Cardiff. A fantastic cross by Craig Noone was met by a towering header from Jordon Mutch, although Stekelenburg was equal to it there was nothing he could do about the rebound. The ball hit the grounded Sascha Reither and rolled back into the Fulham net.
It was a vital win for Cardiff, one that has taken them level with 17th placed West Brom on 25 points, Fulham however, remain four points adrift at the bottom.
