I enjoy this brand of fan but have a need for high cfm. which of the silent 4 120mm models yeilds the highest cfm?

The highest CFM 120mm model is the Silent Wings Pro 4 120mm PWM. To be sure you are getting the correct one, make sure the specifications page lists the RPM as 3,000. Also, be aware that this model has a small 3-way switch on the back of the fan hub labeled "M/HS/UHS" which you will want to set to the "UHS" setting to enable the maximum speed.

Will this work with a 240mm AIO?

Should be fine as they are designed to be placed on air coolers just make sure that you have enough space because of size difference like width

Silent wings pro 4 vs silent wings 4?

The Pro is more expensive and designed specifically for liquid cooling radiators.
