Ok, that's just weird...who would have thought to counterfeit a cheap-o fan? I can't imagine that there's much money in selling a product which retails for $3-5.

Couldn't the discrepancies be due to lot or material varations? We all know that Chinese manufactured goods don't always have the best quality control or consistency...

Would be interesting to do the same tests described in the XS forums again since it's been 8 months since those posts...and again year from now. I'd do it myself but I don't have the time nor test equipment.

You won't be disappointed with your Yate Loons from Petra's.

Yeah but that's not a refresh of the Yate comparison...it's a comparison between different brands.

All I'm saying is that between batches and lots, it's entirely possible that the manufacturer got different materials. When Vapor from XS got his batch from Petra, maybe they were from a different manufactured lot than the ones at JT?

It's just really hard to swallow that someone would counterfeit $4 fans. It's like a guy with a press in his basement that makes counterfeit nickels.

Interesting...after doing some research, I found this post on another forum by Jab-Tech. It appears that the difference is batches - not counterfeiting.

I do believe it's possible they are not fake, however a large batch from you guys was shown to be different from the ones sold at other sites. They would not put out as much CFM and many had problems (I too have a problem one it started vibrating last week so much that it will walk off a flat surface.. it was one of the new #7XX ones).

http://www.xtremesystems.org/forums/...d.php?t=151144


I do enjoy buying from you guys though. Really fast order processing and shipping as well as great prices.
I want to point out something obvious.

Quote:
:*JT(Jabtech) YL-SL has model # 511 (or five hundred something). Petra YL-SL has model #705
Those are manufacturing dates.. 511 = Nov 2005, 705 = May 2007.. 18 months differance in manufacturing can make a huge differance in the fan.

As for the not as much CFM, I assume you are referring to the Straight Blade / Curved Blade comparison that had a 4% differance. Well within the stated +/- 10%

However none of this is relevant, because every Yate Loon fan be it open corner, closed corner straight or curved blade was manufactured by Yate Loon.

Quote:
:I too have a problem one it started vibrating last week so much that it will walk off a flat surface.. it was one of the new #7XX ones
Expect this to happen, Yate Loon are cheap fans, 50% of the cost is shipping so go figure how cheap these things cost to manufacture. I expect that 5 - 8% of YL fans viberate within a couple months, the other 92 - 95% perform fine for a long time, however sleeve bearings are not going to last forever.

I have 5% return on nexus fans for viberation/bad bearings .. Differance is though YL brand are disposable at $3 and Nexus @ $15 aren't.
