Fan Upgrades

[Methanoid]

I have a Define R5 which is filled with HDDs... However the stock Fractal fans do not keep my HDDs cool enough...

Fractal specs
Revolutions: 1000rpm • Air flow: 116m³/h • air pressure: 0.71mmH₂O • Volume: 18.9dB(A) • Connector: 3-Pin • Voltage Range: 4-12V

Mu understanding is that its Air Pressure I need to seek on replacements to ensure they force air past the 8 HDDs in the drive bays... I dont want anything more than 20db noise


There is a shopping comparison website which allows you to add filters and I have now found some candidates:

Nanoxia Deep Silence NDS 140, 1100rpm
Revolutions: 800-1100rpm • Air flow: 89-116.4m³/h • air pressure: 0.69-1.08mmH₂O • Volume: 9.1-14.4dB(A)

Nanoxia Deep Silence NDS 140 PWM
Revolutions: 700-1400rpm • Air flow: 129.9m³/h • air pressure: 1.18mmH₂O • Volume: 16.2dB(A)

Phanteks PH-F140SP black
Revolutions: 1200rpm • Air flow: 139m³/h • air pressure: 1.33mmH₂O • Volume: 19dB(A)

Enermax T.B.Silence PWM 140mm (UCTB14P)
Dimensions: 140x140x25mm • revolutions: 600-1200rpm • Air flow: 67.08-117.30m³/h • air pressure: 0.691-1.131mmH₂O • Volume: 9-15dB(A)

Cougar CFD D14HB 140mm black
Revolutions: 1000rpm • Air flow: 124.40m³/h • air pressure: 1.4mmH₂O • Volume: 18.0dB(A)

Any views/suggestions/recommendations/refutations (of my statements about air pressure) ????

Please do not believe published specifications. They are often very inaccurate, and even if they are, The airflow rating is free airflow (fan in open space with no restrictions) and static pressure is maximum pressure reached when resistance tops airflow (fan with cover taped to exhaust side).

Phanteks PH-F140SP should solve your problems.

I'm hearing good things about the new Phanteks PH-F120MP and PH-F140MP. I have used PH-F120MP and it is a good fan, but I have not used the PH-F140MP .. and they are three quid more expensive.

A bottom intake as well might be in order. I have Define R2 and have built several R4 cases with 2x front & 1x bottom intakes. Remove all unused PCIe back slot covers and not top exhaust works quite well. Some I have removed the bottom and back grills as well. This not only improves airflow, but lowers noise levels. Oh!, I almost always use PWM case fans controlled by CPU and/or GPU PWM signal/s. This means case fans cycle with component temp and fan flow demands .. very quiet unless system is working hard. The cases that are not using PWM fans are Phanteks, and they use the Phanteks PWM controlled variable voltage fan hubs. These hubs work well,but not as well as PWM fans.
