'Quiet' fans for push/pull on TRUE cooler.

post #1 of 19
Thread Starter 
One of my scythe ultra kaze's has a failing bearing and needs replacing. as it stands, I have not had them over 1/3 power in the past few years anyways, so no need for crazy CFM.

What is the current consensus for quiet fans with good airflow? I'm undecided if it's worth going PWM considering it will be push/pull.

You dont need to pay attention to the airflow for a heatsink,you need to worry about the static pressure,check my guide in the FAQ there are a lists of good fans for heatsinks

Thanks for the response. Your guide is certainly informative. I've always liked the Corsair fans, is there much difference between the PWM and non-PWM high performance fans?

I would fall into overpriced corsair fans. I would go with
120mm Fans
Akasa Viper 120,Akasa Piranha 120,Noiseblocker NB-eLoop B12-4,Rosewill RFX 120BL,Rosewill Hyperborea 120,XSPC Xinruilian 120mm 2000 RPM.

But if you go with corsair the PWM version will let you adjust the fan speed via bios

Static pressure and airflow are both important... but the way they are used in spec sheets is kinda stupid.

We don't use fans at their static pressure rating.. because it's the maximum amount of pressure the fan creates when no airflow.. static is stopped, still, not moving.

We also don't use fans at their CFM rating... because that is taken when fan at full speed with absolutely no resistance.

In real world use we have at least a grill resisting the airflow... and even the most open grills restrict airflow
2-3% of airflow according to Puget Systems.

28-29% according to Silverstone.

I agree with you on overpriced, but finding the other ones in Canada is a bit of fun and with shipping equates to similar if not excessive costs.

Then go for the performance version SP

To my understanding the non-PWM will run at 2350RPM always, whereas the PWM version will only spin up that high when needed, thus being quieter during day-to-day stuff. Would I be correct in assuming that?

You can voltage control them but voltage control fans will not run at as low an rpm as PWM control will on PWM fans.

More of an issue with higher rpm fans.

I can personally recommend the Swiftech Helix's. I have some 120mm's and 140mm's and they are both very quiet (well that is until you ramp them up to like 60%, which for me is always haha), great static pressure and CFM for the money. Wait for a sale, get em for $10 each, in Canada (I got them at NCIX) thumb.gif
PS: If you actually go drive down to richmond or a different store, you can actually talk to the person and probably get a small discount.
