Hi, Wix.
Thank you for the extra info and the photo.

Don't know the spec of the motor but since it's for the rad fan, should be enough flow rate.
You'll know when measuring the pressure on a hot summer day.
Should become handy for other owners in the future.

Had a quick look at your build thread as well.
Since you have disturbed the a/c system and replacing the condensers using new/used parts, best flushing the system while you have extra space.
And seal it unless you are evacuating the system immediately afterwards.
As it's off topic from this thread, I won't go into detail.
