GELID Silent Pro 14 PWM Case Fans Review

Cooling/VGA & Other Cooling by stefan @ 2016-07-18

The new Silent Pro 14 case fans from Gelid did impress us positively because they are able to drive plenty of airflow while staying silent enough. The PWM feature means that it is not mandatory to have them connected to a fan controller in order to regulate the speed, but the fan RPM will be modified continuously based on the load of the system, when plugged in to the motherboard; PWM profiles can be also altered via the system BIOS in order to have a perfect balance between noise and cooling performance.

Test Setup and Test Results

Test Bench:

-BIOSTAR Z170GT7 Motherboard

-Intel Skylake 6700K CPU @ 4.6GHz 1.285V inside UEFI

-Corsair Vengeance LPX 32GB DDR4 2666MHz C16 Memory

-NZXT Kraken X60 All-in-One Water Cooler for the CPU

-HIS Radeon R9 390X

-Creative Sound Blaster ZxR + daughter-board

-AMD Radeon R7 240GB SSD

-SAMSUNG HD204UI 2TB drive

-Toshiba MG04ACA400A 4TB drive

-NEXUS 1.1KW Gold PSU

-InWin 909 Case

Before installing the fan onto the case mounts, we have attached the rubber accessories:

The next step was to mount the fans as intake on our InWin 909 case adapters:

Four Silent Pro 14 PWM fans were mounted as intake, while two NF-A4 industrialPPC 12V 140mm were cooling the NZXT radiator:

Multiple tests followed, with the following configurations:

Test 1: 4xNF-A4 industrialPPC 24V 140mm as intake, 2x NF-A4 industrialPPC 24V 140mm on the radiator (silent profile)

Test 2: 4xNF-A4 industrialPPC 24V 140mm as intake, 2x NF-A4 industrialPPC 24V 140mm on the radiator (performance profile)

Test 3: 4xNF-A4 industrialPPC 24V 140mm as intake, 2x NF-A4 industrialPPC 12V 140mm on the radiator (silent profile)

Test 4: 4xNF-A4 industrialPPC 24V 140mm as intake, 2x NF-A4 industrialPPC 12V 140mm on the radiator (performance profile)

Test 5: 4xGELID Silent Pro 14 PWM 140mm as intake, 2x NF-A4 industrialPPC 12V 140mm on the radiator (silent profile)

Test 6: 4xGELID Silent Pro 14 PWM 140mm as intake, 2x NF-A4 industrialPPC 12V 140mm on the radiator (performance profile)

During the tests, the intake GELID Silent Pro 14 PWM fans ran at full speed (as the Noctua NF-A4 industrialPPC models).
