Nosier than expected!

Reviewed in the United States 🇺🇸 on November 18, 2022

I have one of these & after a couple of years of running 24/7, the bearings started to get noisy. This is the exact replacement & it is only slightly quieter. ??

Not a '4 pin fan'

Reviewed in the United States 🇺🇸 on November 4, 2022

Size: 80x80x25 mmVerified Purchase

The fan has a 4-pin power connector adapter, but it's a 3-pin fan.
It is pretty quiet overall. Starts spinning at 4V, it's close to silent up to 8V and you can hardly hear it from 1m distance at 12V, except when exhaust directed at you. It's a good deal @6.

A Fan Rant

Reviewed in the United States 🇺🇸 on April 5, 2019

Size: 80x80x25 mmVerified Purchase

The reason to buy these fans is the dual ball bearings rather than ostensible silence. Some industrial-quality ball bearing fans have (had) a reputation for being crazy loud, and I think Vantec meant to convey these were "quiet" in comparison. Have you ever heard a 6000 RPM Delta fan?

These fans are not unreasonably loud, like Delta hairdryers, but they are hardly silent, and if that is important to you, these fans will not satisfy. Their subtle whirr doesn't matter at my house because it already has as much background hum as the USS Enterprise-D.

Double ball bearing fans used to be standard back in the 80's and early 90's, but as everything moved toward cheapness, the standard was supplanted, first by single-ball bearing fans and finally by full sleeve bearings. Sleeve bearing is kind of a cute name for No-bearing--it's literally just plastic rubbing against plastic. Obviously, this is not ideal from an engineering standpoint and sleeve bearing fans have notoriously short lives.

Sleeve bearings accumulated such a negative reputation that the fan industry invented another term, Fluid-dynamic Bearing, so they could sell sleeve bearings under a different name--one that wasn't synonymous with "junk". Supposedly fluid dynamic bearings ride on a cushion of air generated by canals in the sleeve or something, but don't confuse them with a true air-bearing, which require a high pressure air stream generated by another source and are used in special applications requiring high speeds and high durability, like large commercial copiers. In my experience, fluid-dynamic bearings last no longer than sleeve bearings, which is no surprise because that's basically what they are. They are quieter than ball bearing fans, at the beginning of their lifespan, but start making horrific noises as they age, and they age quickly.

I have 4 cases with all-ball-bearing fans that are over 15 years old and they still work (maybe I replaced one fan that went bad out of the lot), although they are starting to get a little bit too noisy, even for me, so I am slowly switching them out for new ones. If they had been sleeve bearing fans, they would have needed replaced 4 times by now.

Double-ball bearing fans are not very easy to find at this point. Vantec is one of the few choices on Amazon that I trust and I haven't had any problem with the Vantec Stealths I have bought from various places over the years.

Own about 20 of these in various sizes. Use them all over my ATX cases and power supplies. Solid product, high longevity.

Bought to replace Astron power supply (ham radio) and WOW

Reviewed in the United States 🇺🇸 on April 3, 2021

Size: 60x60x25 mmVerified Purchase

My astron power supply built in fan was so loud, it sounded like a jet taking off every time I would key one of my bigger radios to get the current draw up closer to 20A. I have measured temperature, and I'm not seeing any large differences in temps during use. The fan is so quiet compared to the built in fan that I would highly recommend any ham radio operator to change their fan out for this. Great decision!

Replacement for my Synology NAS that was giving me repeated warnings of the fan briefly not working. It's just as quiet as the original in my opinion.

Great reliable fan but Loud

Reviewed in the United States 🇺🇸 on February 26, 2014

Size: 120x120x25 mmVerified Purchase

I should first say that I am very picky about noise in my computer so my standards are likely much higher than the average person. I needed replacement fans for my computer case after one failed. I decided on this fan after a little research. I liked the double Ball Bearing design. I have used these fans before and they are still running in an 10 year old computer. I Replaced two Silenx Ixtrema Pro fans after one failed and I did not realize how quiet the Silenx fans were. These Vantec fans are significantly louder. I'm not sure I will be able to keep them given the increase in volume. I think they are a good fan as long as noise is not an issue. If you are looking for a super silent fan, this is not it, if you are looking for an average fan with great reliability this is a good choice.

Excelente producto

Reviewed in Mexico 🇲🇽 on December 16, 2019

Size: 60x60x25 mmVerified Purchase

Después de 6 meses de uso, puedo confirmar que este ventilador funciona perfectamente, no es 100% silencioso, pero no es tan ruidoso como el que traía originalmente el gabinete de mi pc, El original solo duro 3 meses antes de hacer el clásico ruido de carcacha, en cambio este trabaja a la perfección despues de 6 meses. Recomiendo altamente su compra si cuentas con un gabinete slim.
