Not the easiest of graphs to follow, especially with no context in terms of other fans but I had to start somewhere!
Both noise level and airflow were measured 6" away from the fan and fan/radiator respectively. I'll get the same tests (and accordingly easier to follow multiple quantiy graphs also) done for the other 120/140mm fans I have here in the same conditions- a single 140mm rad would be very helpful here though as I am currently using an SR-1 560![]()
Are you taking the sound reading with fan on the SR-1 560? To me that would be the relevant sound level.PH-F140MP goes from 500-1600 rpm, as is the case with most 140mm fans. The only other 140mm fans I have are Cougar CF-V14HB, Gelid Wing 14, Corsair AF140, NB PK-2, NB PK-3. Maybe someone else can compare these against the Noctua/Thermaltake offerings but it only makes sense to do with for the 140mm fans with proper 140mm fan holes since these are meant for rads and used with others alongside.

LOL.You know better than to go by promo videos
There are a lot of other things in there such as the rad on the PCI-E slot and fan in the PSU area as well.

What is your ambient noise level and range of accuracy of your meter? I ask because mine is 30-130dBA and my ambinet is very close to 30dBA. Quietest times show graph of similar or slightly less flatline 30dBA with spikes bouncing to <33dBA.
I measure airflow almost against radiator / cooler .. and move it around some to find the most consistant flow level. I'm planning to make a flow tube with the end filled with straws to align airflow straight out. Tube will also be equipped with an inclined manometer built into it.![]()
Sweet!Yeah with the fan on the rad. Sound was measured in a proper sound lab at my university in a fixed ambient (21 dBA) environment with a maneuverable probe.

Sweet!
Must be nice to have access to great equipment.
FYI: The more or less standard for sound measurements of fans is 1 meter distance, but some use 30cm .. and others don't even say.
- Dimensions (mm): 230x200x30mm
- Current (A): 0.41A ±10%
- Speed (RPM): 900 RPM ±10%
- Air Flow (CFM): 156.27 CFM ±10%
- Air Pressure (mmH2O): 1.81 mmH2O
- Noise (dB-A): 25.6 dB(A)
Indeed.
There are some very good 140mm fans now.
If 120mm was the best size for airflow performance helicopters would have a big frame full of them rather than their present rotor blades.![]()

Do u think using mo-ra3 420 with 230mm fans instead of 140mm ones would have positive impact on temps while keeping the noise at the same/similar lvl?
Something like BitFenix Spectre PRO 230mm Fan - All White.
Use a good air cooler instead and cool just as well with less noise and expense.I have a similar conundrum - I'm about to a Phanteks Enthoo Luxe and Corsair H110. I want fans for both the radiator and the case. I'm after quiet and was going to get loads of noctua A14.... but the colour.... Just wondering if there's anything similar enough acustically with the same performance but that looks nicer... I suppose there's the industrial ones, but those would only be useful for the radiator and overkill for the case. suggestions?

Arctic Cooling F12's with 140mm to 120mm fan adaptors.
there's no such thing as a good 140mm fan.
All these options are bad for radiators, CFM does not matter in this case, it is the static pressure that does. That's why the OP is asking for specific fans that are suited for this purpose.
