Fan for CD/DVD slots

[Chris-.-]

Basically I've got 2 slots since my old dvd/rw fried when I put a new PSU in I reckon and the old slot cover I've lost so I've took the other out and now I'm left with a gap of 150mm by 90mm basically 2 drive slots are open is there any fans that are built for these slots as there is no screws and I don't fancy drilling holes into my case

Thanks for help


Edit:
Can also make room for 3 slots

With 3 slots then I think you could use something like this:
