2 yrs ago, I bought a Taiwan-made fan by TYC for my E53 and have been happy with it.
I would buy another TYC fan for any of my BMW's.

I did some research and TYC has been making electrical auto parts for about 60 yrs. I bought the fan on Amazon and it came with a lifetime warranty from TYC. It was 1/3 the price of a Genuine BMW fan.

^ I agree with all this, except my TYC fan from Amazon came with a 2 year warranty.

I chose based on feedback here and with the TYC brand. Happy with that.

The OE fans have all the motor control electronics within the motor assembly. Most (all?) aftermarket ones have the separate box as yours does. I see it as a design difference but not necessarily a problem.

My Foxwell has a function to spin the fan up, so you can test it independently of any AC control logic.

There are additional ways to get the ECU to spin the fan at full speed for testing if you want. I have experimented and posted on that in the past here. Things like pulling the AC pressure switch connector, putting in a resistor to simulate high temp on the lower radiator hose, etc.

I bought mine in June 2021...In my Amazon Orders page, it says "Product Support" ended in June 2023 - 2yrs...But I don't know what that means.

The Manufacturers warranty , which is still attached as a PDF both below and to the current TYC Amazon listing linked above, shows it has a non-transferable Lifetime warranty from TYC.

Saved a copy of the PDF, just in case. Thanks.
