120mm Fan Questions

My case has a mesh panel side with rubber grommet holes for four 120mm fans.

Here's what it looks like: (side pic in gallery)

The holes are pretty big... like you could slick a pencil through them. The screws that come with the fans obviously aren't going to be big enough. What do I do/buy/use to get it to work?

Also my motherboard only supports two fans... so unless I'm missing something, I'm going to have to connect them via molex on the PSU.

It's confusingly hard to find molex fans on NewEgg because I see most listed as 3 or 4 pin, and if there is a picture of the adapter, it still looks like a tiny CPU fan plug. I've only seen a handful of fans that look like they have a molex plug.

So if I did get a mobo fan, it seems like I'd have to get a 3-4 pin adapter to molex. The problem is there aren't any on NewEgg and only a few on eBay. That makes me think I've pointed myself in the wrong direction.

I really can't be the first person to run into something like this. A lot of people put extra fans in their cases and don't have ten thousand mobo fan plugs. So what am I missing?

Ideally I'd like to use these fans if they'd work:

BONUS:

The plan is to put 3 on the case and 1 on the other side of my Hyper 121 plus. It's going to be okay if I use a y adapter plugged into the mobo so both fans are controlled, right?

Sorry if I sound like a rambling alcoholic. I haven't been to sleep yet.

Instead of using screws on the side panel I would suggest using the Rubber Mounts

They will fit perfectly into those holes and also save you from vibrations.

The fans you have chosen give you 44.7CFM @ 19.1dBA the only saver is the 4 in 1 pack for 19 bucks.
My suggestion to you would be to go for cougars.

That's 15 Bucks a piece but gives you 60CFM @17.7dBA
and plus the look really great.
and they come in lovely colors... :)

Yup this will work, the 4th and the 3rd pin are usually for measuring the speeds and controlling them.
