Con i use an external GPU in my pavilion dv7 3020el?

[cdgb1]

Hi, i've got a pavilion dv7 3020 el and i use or for gaming but the GPU is old and it heat up too much (107°C) in all games, eventuali in games that requires low specifications. The PC have an express card port and i want to know if i can use an external gpu with external PCI Express and Express card. If i can, Will i have any problems with temperature or not? And is Express card slot 1x ( as wireless slot) or 16x (as normal gpu slot)? I want to use the Nvidia GTX 1050ti by gigabyte. If i can't use it, what are the GPUs i can use?p.s. Will i damage the motherboard or other hardware?

You can do this and it will work but you are very astute to ask whether the Expresscard slot is 1x or 16x. It is 1x. However, I have actually seen people use the Expresscard slot and an Expresscard eGPU and get decent framerates. The answer I guess is that the 16x capability does not come into play much. I am sure it would be even better if the slot were 16x. 

Expresscard eGPUs are getting hard to find but still out there:
