Best fan for a quiet 54MM 30FPI Radiator

Recommended Posts

Hey everybody, 

 

 Recently I acquired a Koolance 30FPI 54MM thick 360 radiator for my build in my sig. But I am having trouble finding a good quality set of fans that arent insanely expensive like Noctua IPPO 3000s.

 I would like to do a push-pull setup on the radiator and am asking as to what you guys reccomend. I currently have Servo Gentle Typhoons (1850RPM) fans on my Coolermaster Seidon 240

Swiftech Helix 140PWM fans are pretty good. Have a high static pressure and go all the way to 1800RPM. If you live in the US they usually go for 15$ or so each.

I bought 3 Bitfenix fans for my 8 year old 360 radiator. $12 each.

The rad cools a 980 strix at 1342 core clock and 3506 mem clock to 39 degrees celcius with 30 degree ambient.

It also cools the CPU (i7-4790 at 44ghz) cores run from 48 to 57 degrees C in BL2)

all this and the fans are running at approximately 800 RPM.

 

1800 rpm fans are a bit noisier, so try to get 1400 or so rpm. (Unless you live in Death Valley)

With all my fans at 100% my system outputs 41db, and only 30db at idle. Pretty darn good considering I have 6 of the Helix 1800rpm fans in my case. With an extra NF-F12 & NF-A14.

I took a look at the stats of the Helix 140PWM and the 2 latest models of Bitfenix. The non-PWM version is much lower in terms of RPM. So you do save a bit of noise output, but you have a significant loss in Static/Air Pressure which is something worth considering for radiator usage. Not worth it IMHO, considering a PWM fan can be regulated to run low when the system is idle, so you get massive decrease in noise output. as I mentioned in my above post, my system idles at 30db, it's barely noticeable 4 feet away.

 

On the other hand the PWM version of Bitfenix seems to be quite the beast! It's got an even higher static/air pressure than the Helix 140PWM. And it gets apparently an extra 30-ish CFM in airflow, with about 0.5 mmH20 in air pressure. With a measly 0.4 increase in db output! :O I'm impressed! And one could say that the Bitfenix fans look a bit snazzier than Swiftech fans, and they come in all black where switchech are black & white. All that for an extra 2.45$ USD. I have to say that the pricing of these fans is rather competitive to Noctua, they have their 140mm PWM fans at 24.95$.

 

Bit Fenix Pro PWM Costs : 16.95$ USD (as per performance-pcs.com) (LINK)

Helix 140PWM Costs: 14.50$ USD (as per performance-pcs.com) (LINK)

 

Here are the Helix 140 PWM stats: 

 

Speed range 700+/- 25% ~ 1800+/- 10%  RPM

Airflow range 35 ~ 90 CFM

Static pressure range 0.25 ~ 2.29 mmH20

Noise level range <8.3 ~ <28.8 dB/A

 

And here are the Bitfenix Pro 140mm stats:

 

Dimensions (mm) 140x140x25mm

Current (A) 0.18A
