Highest CFM case fan with 3 pin connector?

[SeaFoam]

What's the highest CFM fan I can get with just the 3 pin connector, I want to get two of them and hook them to my motherboard so they slow way down when i'm not gaming.

How will they slow way down when not gaming if you have them plugged directly into the mobo headers? If you want to control the fan speeds, you are probably going to need a fanbus of some type. Like the Vantec Nexus.

Sorry if I mis-understood.

Mayb you got them fan temp sensor thing on mobo that speeds up the fan when its at a certain temp?

getting the highest CFM fan with a 3 pin connector and then plugging it into your mobo headers would be an incredibly stupid idea - you'll most likely end up blowing out the headers on the board because they can't take a high load

your best bet is to go with a rheobus if you want high speed fans with easy control

Yeah, high output fans and mobo headers usually don't mix. Some of the better ones come with dual connectors - a three pin to connect the speed sensor, and a 4-pin feed-thru to supply the power.
.bh.

hmm i need to remember that....so don't run a Tornado off a mobo header? you can run it off the CPU HSF header though, right? because my plan was to use a 92mm tornado on a slk-900a...

The 80mm and 92mm tornadoes have a 4 pin molex for power and a 3 pin sensor plug for the CPU fan MB header. It works great on my SLK-947U

It's a good idea not to run any 40+ cfm fans off any of the mobo headers (that includes the CPU fan header).
