Here is a fan out of a 09 mustang 4.0L. Is this enough for the ls motor?

Based on displacement and HP of the 4.0, I'd say no, but you're also not providing enough information for anyone to legitimately answer that question.

I found another fan out of a 2003 Lincoln LS V8 3.9L, end up buying both for $60.
Not sure if the Lincoln v8 fan will be better to run. It has 4 wires, power and ground, and 2 other small wires.

UNSTUCK

But stuck more often.
How that fan worked for you?
For me it’s working great so far. It’s probably the widest fan out there so fitting it is hard. My passenger side head is about 1/2” from the firewall. If you have more gap than that it won’t fit. You’d really have to switch to a car accessory drive system. I cut the nipple off my water pump to clear with a bit of a gap.
You may want to stay away from that 4 wire fan. I’m guessing PWM is a headache you don’t want. Try the other one. Shoot, try the fan that came with the radiator. It might work for you.

It's a decent brand, moves a ton of air so those are good... but you want a puller, not a pusher since your fan will be mounted behind the radiator.
No Way the fan will go behind, no room. Will have to push radiator forward
