takin off the clutch fan to take strain off the water pump and engine
nothin hurts for ur efan to be running constantly its not hurting ur engine like a stuck clutch fan
thats why most ppl remove them,,thats like havin an electric water pump and only wanting it to run when u get hot i mean rly
most people remove the clutch fan because of parasitic drag on the system when the clutch is locked up vs the e-fan which is able to cycle on and off as needed, combined with the little quicker warm up times from not having a locked fan running from startup. having the fan run constantly would remove or at least reduce both of those benefits, because there IS still parasitic drag on the system from an e-fan, maybe not quite as much, but it is still present, mostly in additional alternator drag. you're right that running it constantly doesn't hurt, but it does diminish most of the benefits from swapping to an e-fan. the clutch fan doesn't 'hurt' the system either, its just less efficent, in fact a clutch fan flows more, and is more reliable when it fails than an e-fan (i.e. when an e-fan fails, it stops all together, when a clutch fan fails, typically it locks up and runs excessively, which creates more drag but still cools the engine). I've never heard of someone concerned about the fan causing water pump strain, the water pump and clutch fan are run off the belt like all other accessories, there isn't any strain specific to the water pump that isn't inherent in the whole system.
like I said, if it works for you, then thats fine, I'm not trying to change your mind or anything. I'm just trying to explain why I wouldn't run it that way personally to the OP, and I still would never recommend that method to anyone investigating e-fan conversions.
