[DML] Re: AC went "POOF!"

The OEM fans, when working properly, pull a lot of air that keeps 
the AC high pressure down. In the Texas heat that can be near 300 
psi on a full charge. The fans need to be working at their peak. The 
OEM or DMCH replacements are the only ones I have seen that move 
enough air for me.
