I test fit the Taurus radiator this evening for fit and function. Everything seemed good except that I'm hearing a clicking noise during operation. Watch the video and let me know what you think. The air flow seems good so I'm happy with that. High speed I think would be overkill so I'm just going to run the low speed. Right now I'm just worried about the noise. This is a brand new unit.

Sorry, I never seem to be able to "hear" much in these videos
 
Have you tried running it without the restriction of laying down on a flat surface?

Just a thought.
 
Sounds like something is hitting. Its like a card stuck in the spokes. To me it sounds fast rate, like the blades are clicking across a zip tie. Is it possible that the blade is barely touching some other thing? Those fans are a hurricane. Pretty sure the motor is induction rather than brush based armature. If that is the case, there should be no miscellaneous stuff that could be clicking inside the motor. Since you are committed, take the motor apart and see if a production issue left something less than perfect around the armature. Excellent fan. Nice vid.
 
I had it sitting where air could flow easily through the radiator. Sitting it upright didn't change anything. Here's another video

Loose or damaged permanent magnet. My guess. The variable resistance rotation camming effect is because the poles of the armature are passing the permanent magnet outer which is typical. It is likely a brush motor with wired armature / permanent magnet outer. Take apart the motor. Maybe the brushes are binding when rotated one way and not the other due to improper brush mounting or damage related. Just my speculations. If the clicks are in correlation to the camming resistance effect during rotation, I would say they are related. So, the camming effect is usually caused by simple magnetic attraction as the poles of the armature pass the magnets, this makes me think a magnet is loose.

This sounds like a really good possibility to me also, since it's not plastic deflection from running with almost no load on it. (air load)
 
I have a brand new one of these in a box. Took it out to see. Definitely no sounds. Spinning it by hand is whisper quit and movement is smooth. Although it pulses at very slow rotation, as yours does, because its just passing between the magnets I believe. My guess is that, since it seems to spin well, there is just something a little out of tolerance inside the motor case. If the shroud is cut to fit and there's no returning it, you might as well open it up and take a peak.
Good luck

Ok that's what I needed to know. I've cut on the shroud obviously, but according to my wife who is an Amazon.com addict (I ordered the fan through Amazon), she claims that if the product is defective, they will send a replacement and I just need to send in the old one in within 30 days. So it looks like I'll just be sending this back, even though I've trimmed on it already. I swear, I can't even buy BRAND NEW parts without them being junk or defective. That's how this entire build has been for me. Problem after problem after problem completely out of my control. Talk about wearing a guy down. I appreciate the input guys.

Send it back to china ... :) keep us posted on your fan adventure!

Guys are funny. Everyone says American made is better......Lol it seems that 90% of everything we buy is imported..... The American worker is LAZY as hell. 20% of the american work force does 80% of the work. The others screw everything up and make us all look bad. Sad but true fact the 80% are there to get a check and that is all they care about.

The only reason American made cars are half as good as the imports is they copied and followed the import lead.... Plain and simple and a fact.
 
Well hopefully we all can (make) a difference. I sure am.

Doesn't sound serious to me. Could be that the new brushes need time to seat. Doesn't sound like bearings, more like a "finger" hitting the rotating part, like the baseball cards we put on our bikes so the spokes flicked them and we had a tough ride. If too much to ship back, I would just use it and see if it goes away.

I ordered it through Amazon so they'll take it back if it's defective. I'm just getting to Seattle now and will be home late tonight. The new fan should already be there so hopefully this one is quiet.

What year car is it off? Dimensions?

It's for a mid 90's Taurus. My radiator is 16 X 26 and I cut about a half inch off to get it to fit vertically. There's about an inch or so recess on each of the sides to give you an idea of the width (IIRC).
 
OK so here we go again. What to do?

Is it pulling or pushing air? Does it make sounds even if you reverse the direction it spins? Swap + and - to get it to spin opposite way.
 
It's a puller. The clicking is definitely quieter in reverse
 
You know how a ratchet wrench makes a noise in one direction? Could something be hanging inside the fan itself? The stutter movement I think is normal because of the stronger magnets in todays motors. Do you feel like taking the fan off and looking? Can you even take the fan off?
 
Yup,take the fan off and run it. Could it be out of balance. If worse comes to worse there is a half stripped Taurus at Caseys in Hesston you could snag parts off.LOL
