To help explain the issue I'm talking about, here's a picture of my box:

The fans used now are Sanyo Denki 109R1212H1011's - great fans at high speed, but now that I'm trying to undervolt (and really listening) they emit quite a bit of bearing noise. The only range I'm happy with them in is 3.3-4v or so, and at those speeds I'd guess they're pushing 30-35CFM. Going down that low seems a little pointless...
So I'm wondering if the Yate Loon 1350RPM 120x25mm fans will provide more airflow. I can't dig up any static pressure figures on them, sadly. Remember that these are Chevette heatercores, not like a BIX...they're maybe 2 inches thick, and like pressure. If I got the Yate Loons, they'd be in a push/pull setup as pictured.
Can anyone help me out? My rig is in my sig, all watercooled, with an MCW6002, MCW20A, Maze4 GPU, and MCP655. Overclocking is a priority, FYI, but I'd sacrifice a few degrees for quiet.[/img]
