Question Can i run a GPU without heatsink and fan?

It is probably non functional if it was scrapped.
Likely the cooler was salvaged.
But, you do not have anything invested in it.
I would give it a try. What do you have to lose? 1$??
Direct a fan or cool hair dryer at the chip to get whatever cooling you can during the test.
If you have an electronics store nearby,
you can buy a stick on heat sink like this for not much: - Heat Sinks&utm_source=google&utm_medium=cpc&utm_campaign=Shopping_Fans, Thermal Management_NEW&utm_term=&utm_content=Thermal - Heat Sinks&gclid=EAIaIQobChMI-YyKi8jW5wIVTr7ACh3K3wIIEAQYAyABEgLiQ_D_BwE
Do not try to run a game or anything graphics intensive.

Its still a good card dude
If you're so sure, why take a chance by operating it without a heatsink?

If you did operate it without one, you should absolutely not try to run any 3D apps and since failure/degradation would be more likely to show itself in 3d mode it's kinda pointless to even try. I'd zip-tie any suitably flat and large hunk of finned metal on it before trying it naked like that.

You are brave plugging that into a working PC. It could do a lot of damage. Motherboard is the least of your worries. PSU going on fire, motherboard and cpu dead. Speaking from experience here, had a gpu take out the psu.

Also it could be fine. Needs a cooler, both heatsink and fan.
