The Scythe S-Flex model F should flow ~67 CFM at 12V IIRC. Naturally I will keep it turned down most of the time, but it is nice to know that the capability is there. Thank you for the advice.Zero82z said:Ah, missed that part of your post. With Thermalright heatsinks, you get the best performance with high-flow fans since they use very closely-spaced fins. I recommend you get a fan that pushes at least 60CFM for the best results. You won't need a high-flow fan, but you will get much better performance with one.
