"taking the load off the water pump bearing, that's reason enough to make the change."
If you're going to claim that, seems you should know.
We've been through the freed up HP claims. You don't have any data that shows that amounts to anything worth the trouble either. But everyday experience with similar small fans, suggests that fan in the X5 isn't using enough power to run to make it worth worrying about. That's my position. You have a ~200HP engine and a probably a fractional HP fan. You'll save something, but just like the bearing thing, I doubt it's worth it.

You are correct, I thought it was clear what I wrote was my opinion but I didn't say that. I have edited that post. Let me know if you think it is now clear.
I haven't said the belt causes greater or lessor load than the clutch fan. I don't know for sure and it is immaterial. it doesn't matter, I don't care, say whatever you want, you win, you're right, hail the wizard, you have made your point, you have won the debate, whatever gives you an orgasm.
I do have a range of freed horsepower from both Spal and Flex-a-lite and Bimmerworld and Jegs technical service folks and several other similar estimates from other credible sources. I suggest that is at least some credibility weighed against BS spattered all over the walls.
I am fully aware that there are three camps on the worth of changing the fan. There are those that agree with me, there are those that have reasons to disagree and there are those that spew BS just to be annoying.
Based on my experience and professional input it is a good thing in my circumstances. That's based on the cost of the electric fan components against the range of freed up HP compared to the average $$$ per HP benefit that can be expected from most other performance mods.
Feel free to post a clear message to those that are considering an electric fan that there is no benefit. Please use all that home and industrial furnace fans nonsense as basis for your position. It is the best thing you can do to strengthen my credibility.
FYI, I don't have a 200HP engine. I have a 4.6 with all Dinan engine and transmission mods except a supercharger and meth injection and a 150 shot of nitrous and Dinan Exhaust and electric cutouts when I need open exhaust.
Just for grins, do you think there is a detriment associated with an electric fan. I take that back, I can't be civil if I hear much more from you.
