[Official] Gentle Typhoon 2150 Group Buy Thread - Page 233

My fans were delivered August 3, and I picked them up Aug. 6. I took a quick peek at a few of them that day and 3 of the 4 fans I looked at were damaged. Upon closer inspection today (Aug. 7) I was somewhat relieved to find out that only 3 of the 17 fans could not be fixed to a like new condition, due to broken struts.

Pictures after my response to the quote below.

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.

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.

I think Buska's 4 "decent" fans are actually within spec. All of my fans "wobble" between ~0.5mm - 1.5mm, and most of them (maybe 75%) are ~1mm. You can check yours by finding the high and low point of the blades against the frame when they are spun 360*.

The length/width of the GT's is 119mm +/- 1, and the depth is 25.5mm +/- 0.5. So I would think that a 2mm "wobble" would be acceptable. The only way to know for sure is by turning them on and checking for any abnormalities.

Krusher, did your broken fan look like this?

I was thinking of using JB weld on my broken struts, but I'm afraid I'll damage the fans more if I move them back in place.

I may crop and re-size these at a later date. Nevermind, PhotoBucket re-sizes them automatically. If you need bigger images let me know.

Fans in their original box. The empty space at the end was filled with cardboard and paper. The wires were more neatly tucked away, similar to the left pile.

Interesting choice of paper (Physicians Desk Reference).

The fans.

Open the next picture in a new tab and refer back to it when looking at the spoiler's pictures.

I'll test the fans on my Rheosmart 6 in a few days, then I'll post the results here. Hopefully there aren't any abnormal noises.

Wow, that is unfortunate. Do you have the broken piece, or was there nothing in the box/package? If there was nothing, I'm not sure how it made it's way to you when the damage is quite obvious. But if you do have the broken piece, you may be able to glue it back in place.

I wonder if the crate was dropped when it was transshipped.
