Q: Noisy fan on MBA 2012

Hi,

I wonder if anyone can help! I have a 2012 MBAir. (with Intel Core i7). Last week it started to make a loud whirring sound from start up which I presume is the fan. I'm not smart at this stuff so after searching the internet I did an SMC reset, a PRAM reset, removed Adobe, scanned for viruses (none), checked the CPU usage (nothing odd running over 10%) and checked the fan speed (it's running around 2000 rpm) and the temperature isn't hot. I'm not sure if these are connected issues but I installed El Capitan the week prior, things seem to be running a bit slower than usual but nothing terrible.

 

Weirdly, one night it just stopped and I thought I must have done something right! Two days later it started whirring again while watching a video. 

 

I just wondered if anyone had any gems of advice and might be able to help?  It would be really appreciated.


Thanks in advance.

Karen
