case fans

[ucvb6]

hello,

i never thought about getting a case fan until i read a thread about how important it was for airflow inside the case.

i have an Enlight Medium ATX Tower Case Model EN-72370X3
my question is, are are case fans the same size? what rpm?

really lost on this, any help would be appreciated,

They are not all the same size. If you don't want to mod the case you will have to get 80mm fans to fit. RPM doesn't really matter. It's airflow (CFM) and noise (DB). The Panaflow L1A's are very good for CFM/Db ratios. Check out gizzo's fan page, it has a lot of data on many differnt fans.

I have 80mm Enermax thermo cooling fans that snap right on to my Antec case. For me, I wanted a good fans that perform well but at the same time, I like them to be as quiet as possible. For this reason, I got these enermax fans because they fit the specifications I needed. They have thermal sensors on them, so the hotter the inside my case is, the faster the fans spin. I recommend ballbearing. Any how, the way I set it up is that i put 3 fans in the front as intakes, and 2 in the back as exhaust along with the power supply fan. You want to try to make it equal to create an even airflow. Enermax fans are like $5.50 bucks and I'm very happy with them. I also heard the Panaflo L1A's are nice too.

I have heard that the panaflos are nice too.... but when I was comparing the stats, they don't really push that much air..... (generally about 20 to 30 cfm for a 92 or bigger fan... that's not very impressive compared to other ones...)

So I'm confused too about why people say that panaflos are nice...

oops.... i meant 40 to 50 cfm

Fan selection depends on how much heat is generated by the components in the case. High speed Tbirds, burners, multiple hdd's and some video cards can really pour out the heat.

With your case, an 80mm fan mounted in the rear blowing out is a good place to start. This method exploits the slots on the side panel as intakes, and conforms to AMD's recommendations-

If you have a minimalist Intel system, then a low flow quiet fan will do. With AMD systems or plans to include more components, then something midrange or even high flow would be better, depending on how much noise you're willing to tolerate. Various mods can increase airflow, removing the stamped fan grilles and using wire grilles is the easiest.

The temp sensing fans aren't very sensitive to changes in temperature, if you go that way the fans won't react well to changes unless you tape the sensor to something that gets warm, like the top of a hdd..

Several online vendors carry good lines of fans, Teamawe.com and 2cooltek.com both carry panaflos, some of the best.
