They won't be reliable but could be used for testing.

Where can I buy these fans? I can't find any that will fit. The driver card uses a1837 and c4793.
So they are crammed on there. Is there a way to reduce the heating issue.?

If no one else can answer your question, post a photo of the board and fan.

You can get them from digi-key or mouser. They're 40mmx10mm. The originals were probably rated at about 5-6cfm. 9+ cfm fans are available but are a bit noisy.
