It's tricky to hold in place so I've used some aluminium tape (I think that's what it's called) which works well as the adhesive is quite strong.
I tried something more dense and it didn't help all that much. Since I reduced the airflow through the filter so the air now gets into the system through the 5.25" (and the 3.5") slots. Adding a floppy drive / extra optical could probably help.

I think that might be why they discontinue the Eclipse.
