Three aspects of drawing power from a single fan header on the EVGA CLC 280.
Three aspects of drawing power from a single fan header on the EVGA CLC 280.
Here are the details you provided:
So here are my specifications:
msi z370 A-pro mobo
i7-8700k
32gb ddr4 ram
gtx 1080
I recently upgraded my h60 to an EVGA clc 280, replacing the stock fans with two Noctua NF A14 ippc3000 fans.
There are three cables branching from the clc 280:
1. A mini USB cable linking to a USB port on the mobo for EVGA software control
2. A cable connecting to the pump header on the mobo
3. A cable splitting into two fan headers, which will go to the two Noctua radiator fans
I don’t currently use the third cable; instead, I connect the two radiator fans directly to the mobo’s CPU_FAN headers. This allows me to adjust their RPM in the BIOS, but not via EVGA software.
Question: If I connect the two radiator fans using the third cable (to control them through EVGA software), does that mean all power for the pump and the two radiator fans comes from just one pump header? That would be three devices drawing power from a single header. Is this safe? Would it overload the header, and could it handle running all three at full speed?
Thank you for your feedback.
It isn't hazardous, but you may be able to locate the maximum draw load in diagrams elsewhere. Certain MB vendors excel at offering these specifics.
You might also discover a PWM splitter that supports power from MOLEX or SATA sources while maintaining the header speed signal. I’d need to search further to confirm if such an option exists.
Make sure the fans are linked via that Y cable.
Check if the Noctua fans you own consume more power.
Don't worry about it.
No, I think the noctua are limited to a maximum of 12V, similar to the standard fans. Since the single pump header is the sole power source for the pump and the two fans, I was concerned it might experience too much voltage when running all three at full speed.
