I just sent this email to Thermochill but thought it might be appropriate to post it here. Please excuse if the answer is common knowledge to all who post here, I am but a newb in awe on these forums.

Here's the body of the email:

I want to use my PA120’s (I now have both the 120.2 and 120.3, will be buying the 120.1 soon too) as they were meant to be used. My understanding of the situation is:

I know that the PA120 line benefit more from lower CFM fans than do the HE series.

Of course that’s not to say that higher performing fans won’t outperform lower CFM fans on the PA120, just that the efficiency of the lower CFM will be better.

What I don’t know is where this line is. You say lower than 100CFM but I’m sure there is a scale up to that figure such that diminishing returns start to happen much earlier.

Can you please elaborate on this?

My goal is to have the most efficient fans on my rads as possible. I don’t want to get into the situation where I’m adding CFM (and noise) for 10% (or less) gains.

Thanks for any help you can provide.
