i'm curious as to why you need to buy ls1 fans or 05 silvy fans. Why can't you just buy an aftermarket universal electric fan and a thermostat/wiring harness for it?

 

I think the reason why those fans are sought after more is because they are a direct fit if associated with the right radiator brackets... im sure there are plenty out there they will fit or you can make them fit. And as for a harness... idk... but you can just put a switch on there, lol make your truck look more like an airplane control board

 

You can usually find ls1 fans for a pretty cheap price and EAD Performance has a damn good price on the 05 GM fans. The flex a lite dual fan setup is a nice package but the controller box that comes with them isn't worth a ****, there has been alot of problems with it. You could probably make any universal electric fan work though.

 

These fans pull some serious CFM's over a generic fan.

 

but with the radiator size, and a low temp thermostat..... i don't see it requireing crazy cfm, specially in new england, where 95 is a high.

 

The latest version of the VSC seems to be just fine, the earlier models would fry themselves, of course mine took a dump while I was towing. The new version worked great for me.
