h100i gtx cooler fan 0 rpm

Hey, I just got me an h100i gtx water cooler and asus z170 pro gaming mother board. At 1st i had problem connecting the device via usb, but somehow windows (7 ultimate) found the suitable drivers.

 

So my problem is that in CL the cooler fan RPM is showing 0, also the fan is blinking red in preview. Yes i have the latest version. I am able to change from quite to performance mode and the fans correspond to that like they should, so no problem with that. I tried disabling Q-Fan control in bios, but that didnt helped (also lost the chance to swicth modes, so I set to default). I uninstalled CL link, make sure that is plugged into CPU_FAN, made tons of restarts but the fan is still blinking and showing 0 rpm. Also in the bios the CPU FAN RPM at the moment with default settings is N/A.

 

I am kinda lost, any help would be much appreciated

1. the fans are connected to the cooling block?

2. USB from the cooling block to the motherboard was connected?

Yes the fans are connected to the cooler block,

and the mini usb is also connected to the usb 2.0

the fans are physically spinning?

or the problem is only in CL to monitoring the RPM ?

you can see the Temp of the block in the CL monitor ?

Yes the fans are spinning normaly (faster in performance mode and a bit slower if i change to quite mode).

 

I can see the temperature of every other component in my pc via CL, including pump rpm, cooler temperature, also graphic card ...

 

It's just that fan cooler is blinking red and cooler fan RPM is 0 in CL.

 

Should i try connect the cooler via 3pin molex directly to the PSU and then set CPU_FAN to ignoring in bios?

yes, you can.

but did you try to connect the other fan connector ? like SYS_FAN and see if RPM displayed on the bios screen ?

you have 2 X CPU_FAN , did you try the other connector ?

Looks like everything works normaly now when i pluged the cooler into CPU_OPT.. The CL is showing normaly and everything working as it should..

 

Is it possible that there is problem with my CPU_FAN socket? Should i return the mobo or am i OK with CPU_OPT ?

Even if i plug in CPU_FAN just a normal fan, i get an error saying:

 

CPU Fan speed error detected.

 

So i needed to ignore the speed in bios.

 

Thanks alot stale ! it kinda works now

Great,

if the CPU_FAN not working,

Before you take the motherboard to RMA,

I suggest try that:

- reset the bios to (back to default settings)

- Update to the least bios version.

it's may fix your problem

Try reseting to default,

bios is up to date but the error is still there.

 

I am not sure if i want to return it, because now its working on CPU_OPT without a problem.

 

Will running a cooler on CPU_OPT with time make any problems?

 

Also I could run cooler directly from PSU right? So there wouldn't be any need for attaching anything to CPU_FAN, CPU_OPT, FAN_1 slots right?

CPU_OPT connector basically is designed for cooling system with a pair of fans.

at the moment I do not see how you could have a problem,

maybe in the future, but you can always take the motherboard to RMA

YES.

Hey was having the same issue as zupko with my H100iGTX not showing Cooler Fan RPM in Corsair LINK on my Asus Z97 board. Powered down my system, switched to from the CPU_FAN to CPU_OPT, booted up and Corsair LINK now had the Cooler Fan RPM widget with the RPM displaying instead of 0 and blinking red. Works for me!

Hello

 

I'm using Corsair H100I V2 .i have the same problem too.corsair link cpu fan speed is 0 rpm,when i goes to bios it is there

I notice that you all have Asus boards, do you have the Asus software (Fan Xpert etc) running in the background? Link doesn't play well with other software.

Man i solve it well in my case when i connect the pin header i connected in CPU_OPT which i supposed to be correct but NO in the manual said connect in the CPU_FAN, then i connected to CPU_FAN and it works CL4 reads me now the fans RPM and the pump, before connect to CPU_FAN it shows to me fan 0 RPM and pumo in performance @1200 RPM max, NOW it reads me in performance an AVG of 2500RPM and trust me it's a huge difference

hey

i have same issue, cl4 show cpu rpm 0 but sometims show but usually at 0.

i can monitor pump and can change settings(quite,performance) also can change cpu fan rpm when i choose max i heard high noise as well. cl4 is working but did not show cpu rpm well.

Guys what is ur offer ? connect cpu_opt pin or disable q-fan in bios or something else ?

You need to connect the H100i v2 to a header set to 100% or a constant 12v signal. Do not use the BIOS or other fan software to reduce this voltage. If the pump or fans are too loud, turn them down using the Link software.

 

Theoretically, you can make it work from any header, however most people have some benefit in placing in on CPU fan. That header has limited other purposes for case fans and will usually produce a BIOS error when nothing is there. The earlier conversations about CPU FAN vs OPT relate specifically to Asus boards. GA sets their headers up a little differently. Disabled is likely the option you want, although there is likely another way to get the same thing (100% fan/12v).

I also had to use the CPU_OPT for the 0 rpm issue to go away, asus motherboard as well, works fine in this configuration just make sure you ignore the CPU_FAN in the bios otherwise you may get an error message on boot

Hi Guys,

 

I had to set my CPU Fan speed to 100% for the fix.

 

I am running a Gigabyte Z370 Gaming Ultra with the F6 BIOS.

 

Hope that helps!
