is 2015 made , I noticed watching streaming of movies tend to heard the fan noise. Guess due to aging?
 
Fan = high temps. Dust collecting for years? Thermal paste no longer effective? Open iMac and clean.

I imagine it's a combination of the old hardware struggling to keep up, plus the thermal paste not being as effective as before. I don't think there's any easy way to open up a 2015 iMac to clean it or reapply thermal paste though. 😅
 
Dusts tend to be stuck at the back and bottom air vents. I used to have the late 2015 model (i5, Radeon R9 M395X, and Fusion drive), a lot of heat inside that thing.

well , I just let it be. I always try to clean the outlet those holes behind. from outside. Sometime it seem not say loud. Party also due to surrounding temp. I notice the fan noise , etc tend to be not say quite loud if those days feel cooling at least.
 
Hello All,
I'm new here and not sure if I'm even in the correct forum or in the correct post so please bear with me as I try to explain my problem. My 2011 iMac failed yesterday. It starts up, goes to a white page with the Apple logo then the horizontal bar goes to the half way point then the computer turns itself off. The day before all the web pages I select I had to wait for 3-5 minutes before they loaded. So I completely shut down the computer that night and the next morning I began having the problem as describe above. I made an appointment with the Genus bar and they scan the computer. I have a pic attached here as to what they found. What can I do to recover all my data or even if that can't be done. Hopefully, if anyone here can please give me some help it would be kindly appreciated. Please click on pic to enlarge.

HDD showing red, so your data’s likely toast. Hopefully you were backing up that 13-year-old computer regularly; if not then lesson learned.

Replacing the drive isn’t all that complicated but even so, there’s not much effort I’d put into reviving a Mac of that age.
 
Hi Serenity,
I appreciate your reply. So you think I won't be able to find someone that can retrieve the data? I have another mini Mac computer that I'm using now. I had no backup.

2011 iMac?
The GPU may have gone bad.

Try this:
Power off (all the way off)
Put your finger on the shift key and KEEP HOLDING IT DOWN CONTINUOUSLY
Press the power on button and keep holding the shift key down.

This invokes a "safe boot", and (if it's a GPU failure), it should by-pass the discrete graphics and go to the CPU's built-in graphics instead.

Does this work?


Another thing to try:

Again, power all the way off.
Put your finger on the "T" key and KEEP HOLDING IT DOWN.
Press the power button and keep holding the T key down.
Do you get the "target disk mode" icon?
(computer won't "boot" in the traditional sense, you just see the icon)

Try BOTH of the above and post the results you get.
 
Thanks Fisherman,
Tomorrow I'll give it a try and let you know the outcome. And thanks for the tip, my fingers are already crossed.

Hi Serenity,

I mean… you can pay a recovery company to try. Figure minimum $500 and no guarantees at all. That’s $500 I’d put toward a new computer, personally. But the only data I don’t have backed up, I wouldn’t miss ¯\_(ツ)_/¯

I just called 2 recovery services, Drivesavers and another, both wanted 900.00 and up, crazy..
It appears if you call a major recovery service you'll pay premium prices, and that's for a no-rush service. Luckily I have an almost new mini Mac that I'm currently using now and I'm in no rush but all the data I lost, really hurts.
