A few questions for you guys. I need the size of a fan, opinions on buying fans and best way to set them up in a modded case.
--
1)

I know you measure from end to end on the fan. It's the rear exhaust fan I want to replace, I've modded the case for two other fans to help with airflow, but I need a higher powered exhaust now.

It's a HP P7-1003w


Measuring from end-to-end of the exhaust fan is 3 & 10/16ths or 3 & 11/16ths. (inches), which equals 3.6875 & 3.625 (inches) and that equals 93.6625mm & 92.075mm, respectively. (Less my math is wrong...)
(From screw hole to screw hole it's 3.5 In.)

It's hard to tell which reading is the correct one as the only measuring tape I have kinda scratched and marked up and it's either or in-between.

Am I to believe a 92mm fan would fit? OR...

Any insight you can give would be great...outside of buying a new tape, lol.

2)

Also, I would need some recommendations on some Fans, as I just sent back the two 80mm ones I bought, the Mascool 80mm. These were way too loud for the little air they pushed, I think the CFM was labeled wrong.

I need 2x80mm, preferably 25+/- CFM rated, but on the quiet side and 1x92mm(If that's the right size for the back.)

3)

The way I modded the new fans into that case was: I cut one hole on the top(80mm fits perfectly between the PSU and DVD Drive and I cut one hole in the slide panel(towards the front of the PC since my GPU is too tall to have fit it over the center/back area.)

What would be the best way to set this up so I have a good balance in pressure?
I was thinking the 2x80mm blowing in and the 92mm blowing out(My PSU has a fan that can help exhaust as well). If this is the best way, am I correct in thinking that the 2x80mm fans I get should have low RPMs and the 92mm should have a higher RPM?
(BTW, all these fans have to hook into molex, I have no MB plugs.)

Thanks :)

The very best 80mm is the Silverstone FN81. I actually have a handful of brand new and never used FN91's, if you want one just PM me.

I don't have any open pins on my MB to connect fans to and those Silverstones don't look like they come with Molex adapters....or do they?

Hmmm, hadn't thought of that. Should be dirt cheap on ebay. But I think they actually come included. Let me find my stash and check. Man, you need to upgrade that machine to 2013!
