Are you sure that it is FM that is spiking the CPU load and making the fans spin up?
Do you have a second monitor or could you play FM in a window, then you can have Task Manager open along with Core Temp to see what is happening. If it is something in FM, then it's probably worth noting what the game is actually doing when the load\temps spike and report it on here.
It could also just be your setup. FM has long period of idle CPU followed by intensive processing. Other games are generally more GPU dependant, it might just be that your fan configuration struggles to keep the CPU cool at full load and you would need to look into either the fan temperature curve or the overall cooling setup.
