Razer Core X Fan Replacement - Control via GPU Fan Headers

I'm about to purchase the Razer Core X but I've read many reviews about the fan noise.

I've also read that even replacing the fans can be undesirable due to the fact you can't control the RPM properly, and current workarounds involve soldering to the internal board.

My Asus ROG Strix 1080Ti has two additional unused 4-pin fan connectors on the internal edge of the card. Would connecting replacement Core X fans to this be OK? They'd both be Noctua and 4 pin PWM. I'd be wanting to control them via MSI Afterburner or Argus Monitor (I use the latter).

My thinking for this is that the case and PSU fans will match the GPU. All fans will be at 0rpm when the GPU is off and I'd set a minimum 33% RPM (which is inaudible) at idle air flow.

My only hesitation is that (I presume) the XPS 13 2 in 1 7390 (Late 2019) will draw around 40-65W while charging via power passthrough from the enclosure when the laptop is in an off state. In that scenario all the fans will be off, including the case and PSU fans Can 40-65W max be cooled passively and safely for this scenario do you think?

@rodpad Absolutely. I have the same ASUS GTX 1080 Ti GPU with dual 4-pin headers in the back of the card. Mounted inside the eGPU enclosure those headers are right by the front of the Razer Core X so you can easily connect the fans to them. The PSU fan remains running even when the laptop is asleep/off so no need to worry.

@itsage

That's encouraging to hear.

 

I'd be connecting a replacement PSU fan to the GPU fan header which would mean that the replacement PSU fan will be off when the card wants to do 0 rpm surely?

@rodpad Yes, that's the only concern. You can change settings in MSI Afterburner or Argus Monitor to see if FAN-OFF mode can be disabled so that there's always airflow.
