Prospero X3 Fans - Specs?

[Acid Alchamy]

I believe everyone who made the mistake of buying in on Black Arrow's Prospero X3 ended up with at least one usable part.....the Fan...

Fan is made by Trohito
Has 9 Blades
Is Ball Bearing
Runs at DC 12V 3.40A
Model number is VD1238B12HH
18" Long PWM Wires

But im curious to know if anyone has any further specs on the fan?
CFM?
dBA?
RPM?

If I'm quoting this correctly; one black arrow post says "-long life 4 wire 5000 RPM fans" but I cant verify that by no means.
Another post on eCoinTalk says the following "Is it possible to set the Fan Speed lower then 2000? Anytime I try to set it to 1800, it changes it back to 2500. Lowest it will allow is 2000."

I dunno, just curious. If anyone has any info feel free to share. Thanks,

Not everybody got their fans, my order from November 2013 is still undelivered. I really miss my money.

I had a x3 and all i can say, fanns are really LOUD , at 2000k RPM they are like 3x bitmain fans together as in the Loudness.


I sold my x3 because it literarilly sounded like a jumbo jet 747-400
