Good advice. I use a AC Delco thermostatic fan clutchDepends on your setup. Most electric fans are not recommended for 4 core rads as they work too hard to pull through and can't deliver the CFMs. But they look much cleaner. If you're building something extreme that's gonna go over 7k rpm's often, an electric is likely the safer option than a mechanical, but definitely make sure to spend some coin and get a good one.
I've used a few different electric fans, none of them high end by any means, but today I swear by a mechanical fan with an HD or SD fan clutch. Never, ever an issue aside from the chance of the thermostat on the clutch failing, but you have just as much chance of that as an electric motor failing. Keeps my big block pegged at 160-170 even in 35 degree weather. Sorry, thats about 95 freedom degrees.
And if you're going electric. FAN SHROUD, FAN SHROUD, FAN SHROUD. Not just the dinky thing that comes with some of them, something that will funnel the air through the entire rad.
Thanks. Most appreciated. DezGood advice. I use a AC Delco thermostatic fan clutch

Thanks boss !!A reason to go electric fan. No power loss from the belt to drive a mechanical fan. There will be a minor draw from the load on alternator but with a proper fan controller, the fan is ONLY on when the car is stopped, going slow or AC is running.
Pretty much every new car or truck has an electric fan.
I'm also a proponent of the mechanical clutch fan. I use a Hayden clutch and 6-blade fan.
It may be old school technology but still applicable today. It certainly worked well back in the day.Hey! Me too!
