An update for anyone still interested in 27" iMac GPU reflow longevity.
It's now Feb 2022 which is over a year since I performed this. The iMac is still performing admirably!

Hey there; just wondering if the old iMac is still going strong, or has the graphics card conked out yet?

Cheers,

Hi,
As far as I'm aware yes. I was using it regularly until about 3 months ago, then decided to sell. Told the buyer the work I'd performed and then we tested the iMac satisfactorily together. I mentioned that I couldn't give any guarantee on prolonged operation but said if it did prove troublesome to give me a call. I've heard nothing since so I presume it's still functioning well.
For others reading this for the first time, to extend the life I would stress the importance of keeping to the tips mentioned in posts #7 and #21 especially ensuring cleaning of all fans, and removing the HDD and installing an SSD in it's place.

Will be attempting a hairdryer bake and will post results here soon, just for giggles.

Ladies and gentlemen, succesfully reflowed this GPU with only a hairdryer. Heated it up about 3 minutes, close range (about 1-2 inches) and it's working. Will try to remember to write an update here once it dies again.

I’m considering to upgrade 2gb gpu but it’s prize hold me back as it was very expensive in my country.
