spec me a 120mm case fan

[Wing-Man]

How strange.

Is a bit like the Arctic p12 fans that get an annoying pitch around 1000rpm ?

It’s the fan blade shape. They move no air till the RPM’s get up then it should like a propeller

For under a tenner a BeQuiet Pure Wings 2 120mm does "1500rpm, 51.4cfm, 20.2db and has a rifle bearing/4 pin pwm and can be had for £8.99 elsewhere, if that helps. I have 1 in my sff and 1 as an exhaust in my main rig with 2 of the 140mm versions up front and it's literally silent even if they ramp up I can't hear them!

I dont trust rifle bearings which are usually just glorified sleeve bearings

Don't all 'good' fans use 'rifle' bearings though? Or claim they do...

 

[Cyber-Mav]

Most use ball-bearing or fluid dynamic bearings of sort

Is that the fans that tend to be £30+ or is it pot luck?

I forgot to say yesterday, they also have a 3 year warranty so for a wink under £10 surely it's worth considering? Especially how quiet yet efficient the cfm is?

Nop plenty of cheap fans use ball bearings or fdb, arctic cooling fans, thermaltake , akasa, sunon, delta, its endless list.

Ah fair enough.

Ah fair enough.

but same companies also use sleeve bearings in certain product ranges. cost and packaging factors at play. iv never had sleeve bearings last, any and all sleeve bearing fans iv had always failed on me.

so um, what bearings do you like in your fans then

They umm, don't appear cheap after a quick look!

I don't mind my rifle bearing BeQuiets, they're literally silent, move enough for my setup, have a 3 year warranty, no tacky rgb, and cost me pennies under a tenner each.
Cant really fault them for what they do/warranty.

All fans have there place, I’m using RGB sk120/sk140 there cheap as hell but I have a very open easy flow case so they run silent and I can see if there spinning.
And when or if they fail I’ll buy more cheap fans.

But if you want your fan to last 1,000,000 hours at full load then.. you need to pay.


Also just to be clear I have never had a fan fail on me, I’ve used be quiet, noctua, artic and so on.

Nice, I just love how even with non pwm these days you can tweak shiz in the bios, my 140's I chose were non pwm due to being quieter and more than enough cfm, and it was no harder/less efficient to setup in my bias as the pwm on the PA120SE/rear exhaust.

"It just works" as they say.

Yeah all I've ever had was a bearing go which is very obvious noise wise, and I haven't run fans at full whack since christ, socket a days...

a lot of the fans people use at home was never made for home use. when your cooling a industrial sever, 3D printers, CAD machines noise is somthing you don't care about and life span is so is a fan costs £100 they cont case when it runs at full speed for years and doesn't fail. down time is money

when i say fans i mean the technology in the fans, was never made for home use
