Does anyone else have issues with iMovie making your mac sound like its going to take off?
I have a new macbook pro early 2015 and when i use iMovie the fan goes full pelt can i do anything?
MacBook Pro with Retina display, OS X El Capitan (10.11.4)
iMovie is one of the most processor-intensive applications so its generating a lot of heat that has to be dissipated. Make sure that the Mac is not sitting on an insulating surface such as a cushion (or lap) and that the fan air holes are not blocked or obstructed.

Open Activity Monitor (Finder>Apps>Utilities folder>Activity Monitor)

Click on the CPU% tab at the top of the Activity Monitor app window. Keep an eye on this, then launch iMovie and watch what % the CPU tab goes up to.
Keep in mind like GeeD said, Mac's vents totally from from obstruction.
I just did this on my iMac and at first, it was 159% just opening the app. Then shot back down to to below 5% quickly, with just having the app open. If it's constantly running higher than 80-90%, and you have the vents totally free to breath, then it's an issue.
For fan hardware, SMC reset the Mac
