My IMAC, which is now on the Mavericks OS, is burning hot. All it takes is 15 minutes of video or 10 minutes of Minecraft to burn my computer. The fans aren't blaring, but the casing burns my hand. I got my IMAC back in 08, so it's pretty old. Would that in any way impact the heat? Also, why would Minecraft burn my system. I would play World of Warcraft on high and very rarely have my computer be heated up to what Minecraft has. It'd also take longer for it to be heated up.
Why is my IMAC overheating?

I assume "burns my hand" means feels too hot to touch, not causes scarring. If it is causing redness or scarring, go to the ER now, and do not touch it again while playing with games.
The most common reasons for fan noise / overheating:
- Video intensive tasks (HD video or games). Fix: Take a five minute break every 30 minutes to let the system cool.
- (notebook) Using the computer on the bed. Fix: Take it off the bed.
- (notebook) Case/cover attached. Fix: Remove the case/cover. This includes keyboard cover. The keyboard is the input channel for Air.
- SMC is corrupt. RESET SMC. (Link below)
- Hot room (in summer). Fix: turn on the A.C.
- Dust bunnies build up in the fan housing. Fix: Take the computer apart and clean the fan area. (Applies to older computers or those used in a very dusty climate)
- (notebook) Using the computer on the bed. Fix: Take it off the bed.
- Fan is faulty. Fix: Take the computer apart and replace the fan. (Again, applies to old computers.)
