My 5 year old iMac seems to be getting rather hot at the top. Is it possible the fan is no longer working? Is there even a fan in the iMac?
iMac, OS X Mavericks (10.9.4)
The iMac does have internal fans - not sure how many there are in yours, but it definitely has some.
The top does often get fairly hot to touch - I believe the hot air vents through the slots at the top back edge. If you haven't already, it's a good idea to vacuum all the air ventilation areas from time to time (whilst the Mac is switched off). The places to do are:
Doing this can help keep the cooling of the Mac at optimum performance.
All that said, I suspect that your Mac is running at normal temperatures unless you are experiencing other issues - random shutdowns, perhaps.

Run Apple Diaganostics or Apple Hardware Test, depending on which your iMac needs. Either will report a failed fan or fan sensor. Info here:
OS X Mavericks: Use Apple Diagnostics or Apple Hardware Test
Typical behavior for a failed sensor: because the computer can't "talk" to the fans without the sensor, it sets all fans to full speed to protect the components. The sound of the fans are quite noticeable at full revs
A 27-inch 2010 iMac has three fans. CPU; hard drive; optical drive. Not sure about the 21.5-inch versions.
OK, Thanks Paul.
Thanks for the tip Allan.
