[NEW!] LIQMAXFLO AIO Liquid CPU cooler Series Q&A
Find the answers to the most common questions you ask about the LIQMAXFLO Series:
Q1: The user manual states that "connect the fans to the motherboard with PWM Y cable" but no mention of the PWM cable coming out of the pump, what do I do with that? Also which where to on the motherboard?
A1: The red circle indicates the PWM cable of the water block. Use accessory O (PWM Y cable) to connect the fans and the water block in series, and then connect them to the motherboard. If you want the AIO cooler to retain PWM functionality, please refer to the motherboard manual and connect it to a header with PWM control.

Q2: My old AIO Water CPU cooler has two separate cables for the pump and the fan, but I only see one cable now, which fan header should I use?
A2: The fan cables of the LIQMAXFLO series have been optimized for easier cable management. With the new method, if you have more than two radiator fans, they will be interconnected first, and with just a single PWM Y Cable, both of the fans and the pump will be connected before connecting to the motherboard to create a cleaner system look. To activate the PWM functionality, please refer to the motherboard manual and connect it to a header with PWM control.

Q3: The fans are running at full speed even at idle and it's loud, is it defective? (If plugged into pump header)
A3: First, you need to check the definition of the header you have plugged into. Taking ASUS(ROG) as an example, the default mode when plugged into their "AIO_PUMP" header is full speed, which means even connecting a PWM fan to this header will run it at full speed. Since the definition varies by motherboard manufacturer, if you encounter such issues, you can enter the BIOS or motherboard software to adjust the fan mode, or you can connect the fan to another header with PWM control.
Q4: How do I control the speed of the radiator fan(s), VRM fan, or pump?
A4: Please enter the BIOS or use motherboard software to adjust the speed. If you’re using a PWM Y Cable to connect the fans with the pump, it will simultaneously control the radiator fan(s), VRM fan, and pump at the same time.
Q5: Can I set different speeds for the pump and fans?
A5: Yes, you can adjust the speed by entering the BIOS or using the motherboard software.
Q6: Is there an option to turn off the VRM fan on the ?
A6: Due to the 4-pin connector which supplies power to both the VRM fan and pump, the VRM fan cannot be turned off individually.
Q7: How do I configure my PWM settings?
A7: Please connect the cooler to a header with PWM control. For more details, please refer to the manual of the motherboard.
Q8: What speed should I set the pump speed to?
A8: It’s recommended to use the PWM function to let the fan adjust its speed based on the system load. For manual control, it’s recommended to set it at full speed to achieve the best cooling performance.
Q9: Isn't it better to have the pump set at 100% all the time?
A9: If you’d like to prioritize cooling performance over noise, you can set the pump at full speed for optimized cooling. However, if you wish to have a low noise during low loads, you can use the PWM function to control the pump to achieve the balance between noise and performance.
Q10: My system is reporting the RPM at 0, is the pump dead?
A10: If you encounter this issue, please access the BIOS or your motherboard software to check if the fan mode is set to 0 rpm control.
Q11: My system is reporting the RPM at 1207, does that mean it's the speed for both fans, pump, and VRM fan?
A11: The PWM Y Cable which is included with the LIQMAXFLO SR series will detect the speed of the radiator fan, so the 1207 RPM is the speed of the radiator fan. If you want to detect the speed of the VRM fan, you can connect the 4-pin header of the water block separately to the motherboard to get the speed of the VRM fan.
Q12: My fan is barely turning, are the fans dead?
A12: If the fan speed is set to its minimum start-up threshold, it might prevent the fan from operating correctly. Please avoid setting it to the minimum start-up threshold.
Q13: My motherboard is giving me a warning that no CPU_FAN is detected at bootup, what should I do?
A13: Each motherboard manufacturer sets one of the headers to be essential for a successful boot, usually labeled as CPU_FAN. This header isn't specifically for either the PUMP or the fans; as long as it is attached. In the LIQMAXFLO AIO cooler, fans and water blocks are connected through the PWM Y Cable which can be connected to CPU_FAN as a necessary condition for booting. Also, each motherboard manufacturer may have different naming conventions. Please refer to the motherboard manual for more details.
Q14: The header on my motherboard is not supplying enough power, what should I do?
A14: Generally, the current supplied by a header is between 2 - 3A. For the LIQMAXFLO 420mm AIO, the total current is approximately 0.67A (Fan-0.08A*3 + Pump-0.43A), so there shouldn't be an issue of insufficient power from the motherboard. If you happen to have a motherboard with a lower power supply, you can remove the water block's 4-pin connector from the PWM Y Cable and connect it separately to another header to distribute the current.
Q15: What does the included SATA adapter do?
A15: The SATA adapter is an extra accessory that allows you to connect the power supply with any of the 4-pin devices.

What is "Thermal Resistance" of CPU Cooler
| Thermal resistance= (Tc- Ta)/ CPU Input Power = n ℃/W. Whereas Tc= CPU Core temperature. Ta= Ambient temperature. The thermal resistance of 0.1℃/W cooler means when CPU increases 1W power consumption, the cooler will have the CPU temperature increase 0.1℃. Therefore, smaller the thermal resistance value, higher cooling performance of the cooler. |
The Difference Between AC Fans & DC Fans
| AC fan uses alternative current to power the fan, whereas DC fan uses direct current. AC powered fan is usually used on home appliance, big size, high speed fans. DC powered fan is usually used on PC industry, and its fan speed can be adjusted by changing the supplied voltage. |
What are the normal working ambient of case fans
| The conventional case fan working ambient is around -10~60℃. Some of ENERMAX fan has upgraded componments and can extend the working ambient to 85℃ such as Magma or TwisterPressure series. |
What are ENERMAX Twister Bearing Advantage against sleeve and ball bearing
| ENERMAX's patented Twister bearing has self-lubricated composite, therefore, it has no lubricant drained or deteriorated risk. The built-in magnet stablizs the fan shaft and keeps the vibration/friction away. Therefore the Twister bearing has quieter performance than sleeve bearing, and longer MTBF than two-ball bearing. Furthermore, the Twister bearing allows the fan be detached/re-attached for easy dust cleaning. |
How to convert the airflow unit
| CFM = cube feet per minute; m3/h= cube meter per hour; m3/h = CFM x 1.699 |
What is a PWM fan and how does it work
| Common DC fan can be adjusted its fan RPM by changing the supplied voltage. The PWM (Pulse-Width-Modulation) fan uses additional signal to receive the PWM (from MB or other console) to adjust its RPM. |
