Case fans are made to be attached with screws. Get the right screws and you're golden.
Like an idiot I've been trying all kinds of different cooling mechanisms all these years without realizing I can just tape or hot glue fans to things.
I made a hole on the shelf it sits on, added a grill on top and a 120mm fan below. No more crashing
Sure, But why try to fix something that works? :D
Looks fine to me. Just make sure it can pull enough air through those tiny holes. Might need to take a drill to the white casing to open those up.
You could cut the chassis open and use thermal glue to attach a heatsink+fan combo directly to the main CPU on the chassis. Wouldn't look pretty but would probably bring temps to a more manageable point
