iMac overheating. Any suggestions on cooling down?

iMac is 10 years old in a high desert environment and for the past few years it has overheated. It has now reached the point where it has closed down from overheating.

Clarification Request
Tell us if you do the usual.

Tell me about your work with canned air on the vents and if you do your own repairs. That is, would you spend 20 bucks for canned air, heatsink compound, maybe some tool to get in there and watch YouTubes? If not, just get a shop to do a deep clean for you.

I'll add more if I know a little more about your DIY views.

Some folk love to fix it themselves, some need to see the repair counter. If we go down the DIY path I hope to see the exact model so I can find a spot on YouTube about the work.

Depends on the model

I have a friend with a later model than yours. I did a quick search, one day, to see what it would take to get into it to clean out the filter/heat sink. With her model, it's a serious problem getting the glass off the front without a special tool. She hasn't had overheating issues, yet. Even though I've opened and cleaned several laptops, I don't think I'm going to tackle her iMac on my own.

But, I did just clean out her similarly-aged Macbook a coupla months ago. (Was changing her battery, and was annoyed that I needed special screwdrivers to get in. They came with the battery.) The heat sink on that looked like a felt pad was laid across it. It was almost completely blocked.

On an iMac of this vintage

accessing the insides is easy.
Three captive screws and the entire back, including the stand, comes off.
Granted, the current models have the glass glued on but up until around 2012 the glass on the iMac was held in with magnets!
All one needed was a couple of those bathroom hooks, the ones with the sucker on them, and the glass just rotates out of the frame.
That's just the glass! You still have to get the LCD screen out of there.
With patience and the right disassembly guide, I'm sure you would be able to accomplish it.

Sounds like the OP had an easy time getting into it, judging by their problem solved post.
