Best 80mm Side panel case fan?

I would like to improve the airflow in my case. I have a case that caters for one 80mm fan on the side panel (blows air onto the CPU fan). This fan came with the case and i dont think it has a very high RPM.

I currently have 3 fans:
1. 80mm fan which blows air into the case.
2. 120mm extractor fan at the rear of the case.
3. 120mm that blows air onto HDDs.

So what would my best option be for a new 80mm side panel fan?

LOL, i doesnt matter as long as it does a good job hey. I wouldnt mind LED at all. So what would you suggest? There's a retailer here that stocks Vantec double ball bearing 80mm fans that operate at 2900RPM.. Is that any good?

Two words.. Holy S^%$! That thing is a beast dude, na.. Its gona be way too loud for me Im sure it'll cool my CPU like hell, but the noise will be too much. Thanks though..

Any other good options?

I know 120mm fans are better, but my side panel only supports an 80mm fan

Thats why im looking for a very good, efficient 80mm fan..

But thanks bro, will look into it.

Actually, it would be very easy to make the 80mm slot into a 120mm slot. Just get the dremel out and enlarge the hole, drill some screw holes, get a grill and you're ready to go. Here's a picture of my armor where I added a 120mm fan where there was none before (this is before the 250mm fan side panel option came out).
