H100 Pro XT - Readings briefly drop to 0


Recommended Posts

Hi folks,

 

Recently done a case re-installation moving my build into a new case (from a GameMax Panda to a Lian Li Lancool 2), and a new problem has started. On HWINFO64, very briefly my Corsair H100 readings will drop to 0, then return to their actual value. This happens to the 2 x ML120 fans, the pump and also for the water temperature reading. The fans are attached to the H100 directly via. cable. I don't have this issue with any of the other readings on my motherboard.

 

It doesn't look like the fans are actually stopping when this happens, it looks like a purely software/monitoring issue. The fan header coming from the H100 is plugged into a System fan slot, which I've got set to Full Speed PWM in the BIOS.

 

Any thoughts? Spec:

  • Aorus Pro Wifi Z390
  • I9-9900k @ 4.8ghz @ 1.27Vcore
  • 32G HyperX Fury Black @ 3200
  • 2 x SSD Hard Drives
  • Lian Li Lancool 2 Case
  • Corsair RM750i
  • Gigabyte Windforce OC RTX 2060

 

One further question - when I'm installing the whole unit and re-applying thermal paste etc., the only was I could do this was by screwing in the Radiator and letting the pump end hang with the pipes supporting the weight of the pump / cpu block. The unit is working fine, but wondering whether there is any risk of long term / subtle damage or degredation to the water pipes from leaving it hanging by its own weight for the 30 minutes or so that I was re-installing the unit?

 

Thanks in advance

Definitely not an issue. If it can't support it's own weight, it has no business being in the case. Either way, we don't see people showing up saying their tubes "popped off".

 

 

The other thing is most likely HWiNFO and CUE fighting for access to the same devices. In order to run these two together, you need to disable HWiNFO monitoring of the Corsair internal devices (AIO, Fan controller, PSU, etc. Lighting RGB elements do not matter). HWiNFO usually prompts you about this on first launch when it detect the Corsair gear and you can take the recommendation and it will do it automatically. If you already dismissed that, then you will need to do it manually. Find the H100i XT and RM750i in the columns. Then right click the title bar for the section and click disable.

 

You most likely will need to restart the Corsair service after launching HWiNFO, even with these disabled. This can be done from within the settings section of the CUE app.
