I've been dealing with my car making obnoxious fan noises for a few months, at first it would only do it while the A/C was running but now it does it a few moments after the car starts and won't turn off.

Back in July the engine overheated to the point I had to pull over and eventually took it to get serviced. They fixed leaking Coolant, replaced the valve cover gasket and the engine valve cover.

But a month later it is still making loud fan noises and I can't have my A/C running when I drive or Mt engine will overheat. I have an appointment to see the dealership in a week but as of now I have absolutely no idea what's wrong, considering many people have this issue but never actually say what they did to resolve the issue.

Any advice helps I've been worrying about it for awhile, thanks!
