Aftermarket Cooling Options?

Aftermarket Cooling Options?
Has anyone got first hand knowledge/experience with aftermarket alternative Efan cooling systems too the GM system?
I've got the OEM clutch fan and getting ready to tear it all apart to do cam and head upgrades. Thought it would be a good time to upgrade the cooling fan system at the same time.
Truck is a 2000 Z71 Silverado 1500HD 4x4, Circle D 3000 converter, new 34" core rad, 40k gvw trans cooler, a/c condenser. I'll be adding the SLP 180* t-stat but would like to have the better more efficient cooling of the Efans if they're available.

I've had aftermarket fans in my truck. After them I replaced with the stock 05+ electric fans. By far the best fans I've used or seen for our trucks. I bought the fans and all the wiring/fuse panel for $75 at a junk yard I believe. I'd highly recommend them over anything aftermarket.

Seems like the GM retro Efans are difficult to locate here in MD. Often frontal collision took them out or they've already been picked. When I do locate a system almost always something is missing. When they're available prices here are very high and that's removing them yourself of course. Then there's no guarantee.

Thru the grill I've measured the core right at 34". Replaced the rad a year ago with factory rad from GM. I'm determined to find a set of the '05 fans. Once the head and cam work is done I'll install the electric fans rather than a new clutch fan setup.
