I'm considering using an iMac 5K to edit a web series, however, I've read some posts about how this computer heats to over 100 degrees up while editing and rendering. In addition, the fan noise gets very loud. Can some of you please share your experiences with this issue? Have any of you experienced excessive heat and the noisy fan? After using the iMac 5K and experiencing these heat issues would you recommend a Mac Pro instead o the 5K model? Thanks!
