Correct liquid cooler and radiator fan configuration

[Daniel_Khazaei]

Hello guys

I have a few questions regarding liquid cooler setup and other case fans!
Here is the spec of my system:
MB: ASUS Z170 pro gaming
CPU: Core i5 6600K
GPU: AMD RX460
PSU: Green 600w
CPU cooler: Green Glaicer 120 evo
Case fans: 2x Cooler Master JETFLO 120

The cpu cooler has 1x3-pin pump connector and 1x4-pin radiator fan connector. Both case fans have 4-pin connectors. This is my current configuration:

1- Water pump connector 3-pin --->>> 4-pin CPU_fan @ set to PWM in bios
2- Radiator fan connector 4-pin --->>> 4-pin Chassis_Fan_2 @ set to PWM in bios
3- Intake CM JETFLO 120 4-pin --->>> 4-pin Chassis_Fan_3 @ set to PWM in bios
4- Exhaust CM JETFLO 120 4-pin --->>> 4-pin Chassis_Fan_1 @ set to PWM in bios

Q1- Is the liquid cooler system setup correct? especially the 3-pin water pump connector.

Q2- The radiator fan is set to exhaust, but normally the cool air flow should blow over the fins! Is it wrong to set is as exhaust?

Q3- ASUS AI Suite and HWmonitor randomly reports wrong rpm values for the pump! The water block LED shows steady 2250rpm+-5 which is consistent with the pump specification. However, ASUS AI Suite and HWmonitor sometimes report 4000 or 3000 rpm values! Is something wrong with my setup?

Q4- I use ASUS AI Suite to control fan speeds, however the reported speed rang in fanXpert 3 is not consistent with the information provided by the manufacturers. Also, as you can see the reported fan rpm is not consistent with the fan curve provided by fanXpert 3 for all 3 fans! Is this normal?

1-i think if you connect a 3 pin to the 4 pin cpu header you should set voltage not pwm or it will just run at full speed--though never tried but think without the 4th wire theres no pwm

2--have tried both directions with my radiator fans very little difference to be honest and unless the ambient temperature was very low either way round should be ok

3--AI suite 3--the fan xpert part of it any way works fine for me on asus z270-e

thank you for the answers.
Would you please tell me if you are using windows 7, 8 or 10?
Possible to give me a screen shot of your fan xpert 3 settings? (like the one I have posted)

yeah no problem if you give me a minute or two will get you a screenshot

wont post the actual pic from imgur for some reason but got photobucket working now so this one should show ok

Looking at your screenshot made me think twice and tried to check the reported table on the right side of the panel on my system! Well it seems that the reported values in that table is consistent with the real time fan speed reported at the bottom of the ASUS fan xpert panel and HwMonitor!

The problem is with the vertical axis of the graph which shows the fan speed in rpm and unfortunately that is not accurate...

 

[mcnumpty23]

yes was wondering earlier why my vertical is %

and yours is rpm

In answer to Q2: It is generally agreed that performance is the same with either exhaust or suction mounted radiator fans. The benefit of exhaust is that dust collects on the exposed fins of the radiator, rather than behind the fan. This makes for a much easier cleaning job.
