On the way to work this morning I noticed the temp gauge was higher than normal (about three quarters) and the fan was blowing cold air. When I pulled up the radiator fans came on and that was also blowing cold air.
I just drove the car again and it seemed fine, blowing hot air etc, so is this an intermittent fault with the thermostat, an air lock or something more sinister?

All fixed just air in the system, I found some helpful advice someone gave me on here a few years back.

Take off the hose that goes from the actual rad to the header tank (not the expansion pipe), take this off at the header tank end.
Now...
Whilst the small pipe is VTA squeeze the top rad hose (Fat Pipe), before letting go of the top rad hose put your finger over the small pipe and then release the top rad hose.
This process syphon's (sp) water into the rad and air out.
Keep doing this until the water level gets near to the bottom of the header tank, then refill the header tank to the top.
So... (leave cap off at all time)
Fill up header tank until level no longer goes down.
Remove pipe from rad to HT at HT end.
Squeeze and hold top rad hose.
Put finger over pipe from rad and hold it there.
Release top rad hose.
Squeeze and hold top rad hose.
Put finger over pipe from rad and hold it there.
Release top rad hose.
repeat until water level in HT reaches the bottom of it and top up.
repeat this process until coolant comes out of the small pipe when you squeeze top rad hose.
When this happens re-fit small pipe onto HT.
