SpP120 Help

[Fergy007]

Hey

 

I recently bought 3 SP120's, all quiet edition, one of which is PWM and seems great but the other two seem incredibly loud.

 

I have them all installed in my Prodigy NAS, the PWM one is installed on my H60 in the top, the other two are installed in the front of the case to cool the HDD's.

I also have the stock Bitfenix fans installed in the top and back and these are considerably quieter than the SP120's even though they are meant to be "Quiet Editions".

 

I am just mistaken and the SP120's are loud fans or is something going wrong?

 

I have installed the inline voltage reducers which came with the SP120's and on top of that one of my low noise adapter from my noctua heat sink which has brought them down to a bearable noise.

 

Just to note i have the fans running of a Molex adapter and 3 pin splitter as my ITX mother board only have 3 fan headers, 1 for the PWM CPU fan, 1 for the pump and another which is split for the top and the back fans.

 

I hope someone has some advise on this, thanks .

SP's are loud in general. If you already have adaptors on them there is nothing more you can do.

ah, i was worried someone would say that. Would hate to hear what the high performance ones are like =/.

Thanks

Corsair fans are not what people say they are. Just because it's Corsair doesn't mean it's good. Their fans are on the loud side, not too loud, just loud.

You said "one of which is PWM". I take it that the other two are connected to a 3-pin fan header?

They're definitely quiet editions?

 

Anyways, without the resistor they will be running at 12v from the molex (unless you re-wire the molex pins). Any PC fan at 12v is noisey - unless you get something with a very low maximum operating RPM (I have a 700rpm 120mm noiseblocker for example) but ofc that thing pushes very little air.
