I don't think so. This is not definitive as it has not been peer reviewed.
KL5 700 Watt Fan Conversion - 1 or both?

This reminds me that last time I looked, every axle for sale was an AXN on ebay. Couldn't convince the sellers otherwise either!

Just went out and counted 5 rimless blades on both sides for the 2012 NHT Sierra. My 2009 Yukon XL runs 9 and 7 rimmed blades with 700 watt motors. Do not know for certain what motors the Sierra has. Too muddy to see part numbers.

What's NHT stand for?
Both my fans are rimless 5 blades, but I apparently have the 500w motors (non-K5L rpo). I'm interested in changing one to a 700w motor like @Geotrash did and wondering if my existing 5 blade fan can be used on the 700w motor?
My understanding is no because the fan for the 500w motor is a different part number. It’s also why I replaced the fan when I bought the 700w motor.

Don't know if the motors and fans are swappable. I reckon that GM made these different configurations for each other so as not to burn up the motors or draw too many amps.
My Yukon and Sierra run different part numbers for their radiators but from the descriptions at ACDelco they appear to use the same core. Both have engine oil coolers plumbed into the driver's side tank.
There are left and right motors and most of the fans are left or right as well.
Would like to pair the fans up with the blades and shrouds and then see if there are different relays and such.
I had the dealer parts guy check when I did my conversion to 700w fans and he said the relays are the same, connectors the same, this was based on vin number's with a known k5l vin versus my non k5l vin, in addition I have been running the 700w fans for around 4-5 years and have had no issue's. I recently discovered the right side fan motor started to melt the connector a little bit so I replaced both the motor and connector, not unusual for a high amperage part.
