I haven't had much luck with Griffin. This is the second. The first leaked. Summit replaced it. The second leaked as well in the same place as the first just out of warranty. I had a local shop repair it late last year. So far it's ok, but it may be just a matter of time before it does once again. I'm not duprised that the fans are such low flowing.

My dilemma is either to go ahead and work with what I have as the CFM of both together should be ok, or upgrade the fans alone hoping the radiator holds out. I've spent quite of time ensuring it's mounted with vibration and isolation in mind.

The SS radiator mounts sort of oddly if I was to try and locate the whole thing to try. Plus, who knows how that controller would get along with my E67. The SS is an E38 I believe.

Good info here:
