I was in an f18 squadron in my early 20's and that screaming noise those little fans were making reminds me of when they do maintenance tests (idk what they were doing tbh) on the f18's in the hangar. Our offices were like not in the big part of the hangar, but attached so we were like right next to the jets and they'd make that high pitched sound when they really cranked them up lol. Haven't heard that sound in like 17 years.

I'm wondering if anyone has modified some of these fans for Drones? Thinking, if you put Drone type blades, one of these fans would definitely fly. Not to mention, drones all use DC Brushless motors for their fans. I have a bunch of these 40mm fans on Ebay now because I'm stripping down over 100 1U Servers for Scrap. Each Server has 7 of these fans.

Question for the Delta GFB0412SHE @ 3:30 what is the lowest voltage it can take? Like the required voltage it needs to start spinning? Would 5.5v be enough? Sites selling it say the voltage range is 7v - 13v. Your video shows it starting at around 3.7v. Can you test one at 5.5v and tell me if it spins? It would help me alot with something
@HL4EHalfLife

Yes they will start to spin at around 3.5 to 4 volts dc but won't have much power behind it.

I have several of these server fans, they are pretty powerful. I was curious as to how much voltage a 12v AVC 40 x 40 x 28mm fan handle? They are rated at nominal 12v but can handle up to 13.2v The ones I have are AVC 1 amp rated. I also have a 50 x 50 x 28mm fan, rated at 1.65amp. I wanted to overvolt to 15v with a 4S Lipo for use in my RC cars. Do you think the fan can handle 15v?
@HL4EHalfLife
3 жыл бұрын
It should handle 15v just fine. As you can see in this series of videos most of the fans handle 20, 25, even 30v and up but only for a short time.
