Can I interchange GFX card imac 21.5? One is 2009 and another one is 2010
Or will be problems with sensors?

Depends on which model it is. The Core2Duo ones have an LVDS screen and the i5 ones are DP. Those cards have different VBIOS and will not work.

The numbers don't tell me anything. I need to know where it came out of and the 216-xxxxxx number on the GPU.

The card I bought is: Apple iMac A1311 A1312 ATI Radeon HD 5670 512MB Video Card 109-B98557-00. Chip is 216-0772003
I dont know where they got this card.

I want to put to iMac 2009 C2D where original card has 216-0729051 chip.

That will never work in a core2duo machine, not possible. HD5670 will only work with eDP LCDs in i3,i5,i7 machines.

Also buying these cards is hopeless as most of them have been heat gunned or baked and will only work a few weeks/months.

For Core2Duo machines the only solution is to replace the GPU or find a real working 4670m card.

I just said that a 5670 can NEVER work in a C2D machine, case closed. Fix the original card or get a working 4670, which will die again cause they are all 10 years old now.

It will give an image but will have no thermal control and card will slowly cook itself. 5670 is not natively supported on 2011 models so it will not read the sensors on the card.

Ok, I see. But I can use for test
​​​The same will be with Imac 2009-2011 27?
Can install 5670 on them, will be image but not thermal control?

All cards can be swapped between 27" machines always. On 21" all can be swapped as long as it is not a C2D. Of course thermal control problem if card does not originally belong in the machine.
