First time very loud fan using FCPX

[MiniD3]

Hi Guys,
Recently getting back to FCPX to learn colour grading
I have a late 2012 27" iMac, 32GB 750 SSD i7, NVIDIA GTX 680MX 2GB
After about 15-20 minutes of editing with colour grading, the Fan was extremely loud, never heard it that loud before, in fact
haven't heard the fan kick in for years, I think the last time was with a huge PS edit, even then, it was reasonably quite

FWIW, after I closed down FCPX, the fan shut off

Is my old iMac showing its age?
I wasn't game to push it any more until I asked you guys, as I'm certainly no geek
Dont want to cook my iMac just yet!

Is it in the cards to move to M1 style imac or mini? 8-9 years is a good run.

Possible dust is keeping heat from escaping and not cooling as efficiently? I'm always amazed to find where and how much dust collects which will get attracted and cover memory, drives and everything else

Thank you,
Would it be safe to vacuum?
Was hoping to stretch a lot longer,
Budget would almost stretch for a maxed out 27" iMac if I went with OWC ram, which looks like not an option with
future iMacs
You might be right about the dust

The fan was just doing its work, preventing the CPU and GPU from getting too hot. Background Rendering is CPU and GPU intensive, depending on the timeline and effects.

Vacuuming might be a bit too dangerous, due to electrostatic damage. Maybe you have a dust blower gas can (compressed gas)?

As for a new Mac, the M1 Macs are quite fine for the average user, I have the base M1 Mac mini and MacBook Air and use them with HD and UHD video footage in HD timelines and many colouring effects and tracking and such funny stuff. A Mac mini is cheaper than an iMac, and you might even be able to use your old 2012 iMac in Target Display Mode as a display for a Mac mini.
