I took it apart. There is nothing to see. I can only assume the shaft is bent. I tapped with a small hammer that maybe it would set in place (or something), but no dice. It's the same as it always was.

That being said, all the fans have a slight wobble to them, does anyone else have the GT2150s? Is this normal?
5 fans have the SLIGHTEST wobble. 3 fans have a moderate-bad wobble. The fan I took a video of has the WORST wobble.

I shoulda stuck with yates. I hooked up the bad fan to a random PSU and it vibrated like crazy.

thanks for the suggestion about switching out a replace GT fan with the 2150 housing. I guess I'll have to do that to at least two of the fans (wallet cries)

Try PepeLapiu's vibrating GT fix if you haven't already.

Wouldn't work. The actual fan center is vibrating and shaking, it's the shaft... if it was the fan blades, then wouldn't the fan blades alone shake?
A little update on the brown plastic thing:

Didn't work.

I just recorded a video of me testing all the fans. Half of them are bad.
4 are decent. 3 are moderate. 2 are awful.
I don't see how this can happen. It's kinda a high number of defective fans. Does anyone else have slightly wobbly fans?
Could it be the way I stored them? I read on the internet that you should not keep a fan in a vertical position for a long time because the weight of the blades push against the shaft. The article was about fans in general, not computer fans. Could this be the cause? Slightly unprobable because computer fans are light, plus only half the fans are severely affected.

PepeLapiu "theorized that the vibrations were from the blades being unbalanced", and that is what I saw in your first video. So I thought the fix might work for you too.

Quote:
The Sharpie will have left some marks on the blades that are higher then the rest.

It's similar to when you used the tip of your finger to show that one side is higher then the other. (1st and 3rd video)

 

And the shaft is attached to the fan blades, so changing it's angle would change the angle of the blades.

 

Edit: The wobbling is barely noticeable in the "low wobble" set. How did they sound when they were run @12V? And how was the vibration? You can check the vibration by putting the fan on a hard surface (such as metal case), and you can remove the vibration by holding the fan in your hand (not touching anything else).

YAY!

I was sitting at my desk thinking about when I should set up my mail forwarding and happened to remember these fans were coming soon. Check the thread to see they're shipping tomorrow! Wahoo!

That's quite a high defective rate for ya. I got 4 fans. None wobbles. One did have a brace broken though. That causes vibrations sadly. Nothing I can do about that one. frown.gif
