How loud are the Scythe 3000 Ultra Kaze's, really?

post #1 of 18
Thread Starter 
i'm considering getting one for my case as an exhaust fan since it has crazy high CFM.

my only concern is how loud they are.


for those of you that have/had them, how loud are they?



thanks!

They are awful; at full power, they sound like a hair dryer, and if they are undervolted, they make clicking noises. The high speed Scythe GTs are good, as they let you undervolt them without making awful clicking noises. Some Delta fans are also good, as they are solidly built, unlike the ultra kazes.

Why do you need a 3000RPM exhaust anyway?

They are insanely loud and have really crappy bearings. If it were my choice, I'd pick up an AP-30 or AP-31. You can even PWM mod these to help quiet them down.

Quality wise, the Scythe AP-30/31 are miles ahead of the UK3K. (They are built by Nidec Servo, and have really solid ball bearings, though the price is quite high compared to the UK3K.)

EDIT: Art Vanelay, looks like we're on the same page over this, lol.

they are VERY loud. My question would be why you would need an 3000rpm exhaust fan?

They're extremely loud full load, however the performance is stellar. I run mine through a fan controller with NO clicking noises whatsoever...

I used a pair of PWM'd AP-30s on my H80, they maxed out the pump's transfer potential, lol. Same story for you with the UK3K? The AP-30s with a PWM mod however, can run down to about 1000 rpm before they start acting funny, and at that speed they literally make almost no sound at all biggrin.gif

That bearing sound is just horrible. I have a performance 200mm fan with a rifle type bearing. At lowest speed the bearing noise is pretty much in-audible. However when full speed it's quite noticeable and very annoying. I can't even imagine putting one of those things in my room.

I have one as an intake, and leave it off unless I'm gaming, in which case I have it running at 1500 RPM. They are annoyingly loud at 3000 RPM and I'm actually gonna replace mine with the scythe slipstream 1900RPM, which has >100 CFM rating, but are noticeably quieter and near silent at 1300 RPM.
