200mm BitFenix pro Or Corsair ML120 120mm Magnetic Levitation Fan?

[MtSeldon]

I have to change the 200mm fan on my Corsait 600T case. The fan is 20mm thick , so there aren't much alternatives for pwm 200mm fans. One of them is Bitfenix pro . This is not very silent one.

Also there is another solution , using 2x120 mm fans. One would expect this to be noiser solution but considering these are magnetic levitations fans they maybe slighltly more silent.

I'm going to connect them to the Asus Hero VI motherboard with a Y-split cable.

Which one would you choose? Any personal experience with these maglev fans?

Bitfenix specs:

Dimensions (mm) 200x200x25mm
Current (A) 0.33A ±10%
Speed (RPM) 900 RPM ±10%
Air Flow (CFM) 148.72 CFM ±10%
Air Pressure (mmH2O) 1.26 mmH2O
Noise (dB-A) 27.5 dB(A)

Corsair specs:

Airflow 12 - 75 CFM
Static Pressure 0.2 - 4.2 mmH20
Sound Level 16 - 37 dBA
Speed 400 - 2400 RPM

Neither are the best choices if quiet is the goal, IMO. I'd say if those are your options, the Bitfenix would be my choice as it can probably be run around 500-600 RPM and still move a lot of air at a lower dB.

Thank you for your help.

What would be your choice if the goal is to have the quietest option?

Use quiet fans like Noctua NF-S12A PWM or NF-P12 PWM. Or Be Quiet fans as well.

There's finally a good quality, quiet 200mm fan, the Noctua NF-A20 PWM. However, like other 200mm fans, has lowish static pressure, so restrictive dust filters can limit max airflow.

Also vote for the NF-P12 PWM option too. Still one of my fav 120mm case fans - smooth noise profile and effective airflow. Altho a single NF-A20 will likely be quieter than 2x P12s as well as cheaper, so there's that. ;-)

its thickness is 30mm , the fans that came with case are 20mm, it must be 25mm at most.

20mm deep 200mm fan? Yikes! Don't know of any decent 200mm fan that thin.

2x 120mm would the best option then. The P12 or consider the new 120mm x 15mm deep, Noctua NF-A12x15 PWM - it's thin, quiet and pretty efficient.

Or the the Be!Q Silent Wings 3 120mm. Or the Rosewill Hyperborea 120mm - still the best value low noise 120mm fan.

There are maybe four possible choices for a 200mm fan like a Bitfenix (or the stock fans in a CoolerMaster HAF case). For instance, there is an NZXT ~200mm fan that offers up something like 160 CFM in maximum spec airflow. The NZXT does not have mounting holes that match all the rest, but you can kloodge a neat solution with minimal materials and time.

I choose the BitFenix Spectre Pro 200mm fan over the NZXTs and any others because the airflow is at least respectable ( ~ 90 to 100 CFM if I remember). I thought they were reasonably quiet.

Of course, I do things with my computers that may alter the perception and production of dBA and sound. All fans are entirely isolated from metal or solid surfaces of the case. For some, I've even built miniature shock absorbers. I pad the fixed side of the fan-hub with Spire acoustic pad cutouts, sometimes three or four layers thick.
