As such do this at your own risk and if you need to consult an expert. One of the most common hardware failures on all computers not just Macs is continued over heating of the internal components especially the GPU graphics card , and traditional HDD modules hard drives with moving parts.
The following shows the internal temperatures on an iMac 27 inch, Mid with two external displays connected via the Thunderbolt ports. The room temperature is 25 degrees Celsius 77 degrees Fahrenheit.
The iMac has been running for about 45 minutes from cold. To get those temps up a little faster and for all screenshots I had running the following apps Chrome with 3 YouTube videos, FireFox Web browsing, Pages writing this article, Photoshop image editing, Preview screenshots, Illustrator drawing a vector graphic, BBEdit writing code, Skype, and Photo Booth.
