Tim everybody has diferent experiences but, I put on dual GM electric fans and is one of the best things i did. I chose them over other brand because they have a ring around the tips of blades that add to strength. many others just have blade out there on it's own. I have flex-a-lite on My truck and like them. I can hear and tell that they are not as smooth and quiet as GM duals with the support ring around blade tips connecting them together.
Plus I figure I regained the HP lost by the parasitic loss of HP by supercharger with electric fans.
Oh and the A/C works so much better now. I had complained many times about A/C not being cold enough. I was considering a rear A/C unit but that idea is solved now. Well the fan solved it all. Then the Hummer dealer told me that this has actually been a fix used on Escalade owners who complained about poor A/C performance and it solved it for them. More and consitent air flow over condenser coils means better A/C cooling.
