H100i fans aren't spinning at low temps, is this okay?

[Godrick]

Hey,

 

I just built my system few days ago and only just noticed radiator fans dont spin at low cpu load/temps, is this a bad thing??

Should i be doing something different?

The fans are plugged into the fan speed controller splitter that come with the 760t case, and powered by SATA.

 

Cheers for any input

 

 

I somewhat resolved the issue using Asus Suite

Looks like they only turn on at 30-40 percent load

Watercooling fans should always spin because otherwise the cooler doesn't cool. With aircoolers it is okay because they still cool even with the fans off.

 

You might want change the fan profile on those fans to make sure they always spin.

How would i accomplish that?

 

I tried googling i can't figure it out.

 

My fans are currently spinning and in corsair link says they are at 0rpm, not sure in what way i've wired them wrong, if anyone has any feedback would appreciate it thank you

Click on profile and select performance and see if it shows you a number

Hey, yeah it's already on performance, i tried changing sensor mode to "fixed" i dont really know what it does but didnt do anything either : ((

Hm, strange.. It should monitor the RPM correctly. Maybe look up with another software which shows fan speeds if it can detect them

[Godrick]

I tried another software still no reading,

 

i have both of the fans plugged into this header, could this be an issue?

If im understanding it correctly you have both fans on a splitter and then that splitter is plugged into the CPU FAN header.( doing it this way will control the fans based on cpu temp. To adjust the fan speed it will have to be done via your mobo or aftermarket software (not Coursair link).  Hooking it up as I have it below will control the fans based on coolant temp and all setting are changed within coursair link.

 

Heres how I have mine installed and have proper operation.

 

-There should be a lead off the pump unit that gets connected to the CPU FAN header.

-There should be another lead(coming out of the pump unit) with 2 connectors that your fans plug into.

-USB cable plugged into the bottom of the Pump Unit.

-cable to power the pump.

 

Since your not using the leads off the pump for the fans the coursair unit isnt getting feedback that they are running hence why you are seeing 0RPMs in link (the feedback is going to your mobo)

rad fins literally act just like heat Sink fins, instead of cooling air (or using air to cool itself), it cools the water... With a large enough surface area and with a low enough CPU Temp, its fine.

Actually thats exactly how mines set up man, leads off pump are connected to the fans and the h100 to the header

Also bios wont let me change it to spin to anything below 40% load
