I'm looking for some information on the CFM of the fans on XFX 5870's.
I cant find a single piece of information that gives an accurate CFM rate for these fans at relative speed positions, does anyone know where I can find this information?

I'm in the last stages of building my enclosed cabinet and obviously I don't want to push 750CFM through the cards if they only expel ~100. XFX fans are shit at the best of times  Grin

Use GPU-Z to export the BIOS from the card and then load it in RBE to check on the fans curve Wink

Or you can get a BIOS from techpowerup website.

If this post helped you and you feel generous you know what to do: 1P9tXFy9bVgzrfPGeV7F8np26ZtFdCCWvz

Hey thanks for the tip, unfortunately I don't think that shows me the fans output.

I might run into my local electronics store and see if they stock a simple digital airflow meter, should keep me busy this weekend.
