Checked his website, and it looks like Toby's fans are currently sold out unfortunately. I'm planning to take the car in to Danny at DMCCA in July, so I'll probably just end up replacing the fans with DMCH's replacements at that time. Ordered Dave's fan fail unit in the meantime.

So, what we're saying here is that we're a huge Toby fan.
Defective fuses and a temporary Y jumper fix aside: I know we are going against the grain, but here in Florida where we drive all year in a hot climate with the A/C on almost constantly, some of us have rebuilt/refurbished our OEM fans AND run them through separate dedicated relays, one for each fan, together with a more direct power feed. We still incorporate Dave's awesome fan fail unit as source of activation. My car is finishing it's second year in successful testing.
Based on experience, my opinion is there is nothing wrong with an OEM fan (caveat: unit in good condition, and grounded properly). The flaw is that the car's wiring is not up to the task in feeding the power to them. On the Fan Fail socket, all the power is sourced from one connector (pin 87, i.e. the combined wire on the Y jumper). This is going to two high draw fans. It is akin to connecting a high power tool to a long extension cord.
Your mileage may vary.

I had the crimp on one terminal of my DMCH cooling fan bypass Y-wire go bad. This was in a car with Toby's lower-current fans, with all grounds regularly cleaned, and you can even see in the photo I used conductive carbon grease on the spades to help give a better electrical connection. This isn't the only time I've had a bad crimp in this car, which is a little surprising to me, so I've slowly been soldering every crimp I come across "just in case".

Wow. This is a case in point. That is the combined wire/connection, where as you stated, even with low amp fans and good grounds, this spot is still a concern.
I agree. I recommend soldering the connections on this cooling fan circuit. I also recommend only using the Y jumper on an emergency basis.
