2002 Freelander Td4 128k miles
Not long had this car (have only done 250 miles) and have noticed that the cooling fans are going at full speed and it sounds like a bloody helicopter. They don't come on straight away but it mainly happens after driving at speed, even when I've only been on the motorway for just one junction.
Now I'm not sure if the car is overheating and the fans are doing what they're designed for or if I have a fault with a fan speed sensor (if it exists) or something similar??
Could a faulty thermostat cause this problem if it fails to open and is stuck in the closed position?
It's driving me mad to be honest as they're so noisy and even stay on for a short while once the engine is turned off...any advice greatly appreciated.

- It gets up to temperature fairly quickly and the temp gauge stays at the mid-point although it has creeped just over halfway twice in the last 250 miles before settling again.
- The coolant level doesn't drop.
- The engine oil level is fine.
- There are no tell tale signs of impending headgasket failure.
- I've tried bleeding the coolant system but it was fine.
- The bottom hose on the radiator is significantly cooler than the top hose...is this just the radiator and fans doing their job?
- The air-con is off.
