It is probably the fan. Remove the bottom case and check the fan for obstructions and dust. The fan should spin freely, if not then replace it. The next thing to do is to remove the heatsink from the processor and clean the old heatsink compound off and put in fresh heatsink compound onto the heatsink (apply a small amount, too much will just get squeezed out).

@lasdisc , ANDY, It very well could be a dirty fan or a faulty fan. You can use the links below to assist in opening the computer to access the fan, heat sinks, board etc. and give the inside of the laptop a thorough cleaning as shown in the 1st link. 3rd link is your service manual. You should try to isolate where the noise is coming from before opening the laptop, by chance that it is not the fan. If fan is not spinning freely or you may just not trust it, maybe just replace it for piece of mind, Link #4 shows replacement fan, which you can also do a search on for better pricing perhaps. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.
