    How many CFMs for HSF?

    I'm probably going to replace the fan on my TT Venus 12 because I need a three pin fan. The original Venus fan is one of those three blade TT monsters. When looking for a new fan I was just wondering how many CFMs I should look for and what would be the minimum you would accept?

    It's subjective. The question to ask is how many dbs can you stand? Or how much cooling does the cpu need?

    Was it running at low, medium or high? Get the CFMs from TT site and compare them to a new fan you're looking at.

    Well I'll have it hooked up to a CoolDrive 4, so I'll be able to turn it down if want.

    The fan that comes with the Venus 12 ranges from 26 - 76 cfm (or somewhere around there) according to ThermalTake. I would rarely need to run it above about 1/3rd, but occasionally in the summer it would be necessary.

    Sounds like you're set. To me, it isn't about the cfm, but rather the temp's you're getting. I like to keep my case as quiet as I can and under 50 C load.
