Im having problems with my rad fans on my 4x4 sapphire cosworth.

Today when running the car up, the fans were cutting in and out but didnt seem to be running for more than a few seconds, after the car had been running for about 30mins the fans were running for a while, i turned engine off and fans still ran i locked car up and went inside. i came out 25 mins later they were still running so i disconnected the fan switch. About 2 hours later i went and connected the fan switch back up, the fans run for a second and then set the alarm off but continued to stop.

Would this be a fan switch problem or a relay problem?? any other ideas guys please??
