Q: Internal Fan runs at hi speed

Recently the internal fan started running at hi speed after start-up of my iMac 27".  Runs that way for a period of time (30 mins?) and then shuts off.  Doesn't run again until next start-up. Had this problem before and took the computer to the apple store.  They said they couldn't find anything wrong but when I brought it home the problem had disappeared.  Now it is back.  Have tried resetting the SMC numerous times with no results.  Does anyone have a solution other than resetting the SMC?  This is frustrating - I really like my iMac except for this intermittent problem.

iMac, OS X El Capitan (10.11.4), iBook
