Eiswolf 2/ EVGA 3090 FTW Ultra fan header

[beatvjiking]

I've installed my Eiswolf 2 on my EVGA 3090 and it's pretty sweet. It's currently in the shakedown/burn-in phase, once that's done I'll link it to my Eisbaer and have a fully integrated loop

I did have a question about this particular install - has anyone tried powering the pump via the Aux Fan header on the card? I've already linked the RGB to the aux RGB header on the card (I may need to invest in a larger RGB distribution unit...) but I need an extension cable to link the pump to my motherboard, and I was thinking I might be able to manage the cabling a bit better if I linked it to the aux fan. I'm just not sure if it has the capability to run the pump at the recommended max speed, since I can't seem to find a way to change the speed on a fan connected to the header.

This will not work. The RGB connections give you a maximum voltage of 5V. However, the pump needs a minimum of 7V to start up at all. You will have to go the way of the MB. The DC-LT2 should also run at maximum RPM to ensure the best cooling performance of the AIO.

Oh, the 3090 has two headers - one 5V RGB and one standard fan header (as well as three smaller ones for the factory fans, but I'm not using those). I've linked the pump to a motherboard pump header and configured it to run at full speed. The fan header on the card does work to engage the pump or any fan I attach, but since I can't be sure it'll run at full speed, and I can't seem to adjust it via any utilities (including the EVGA X1 utility, oddly...) I've decided to use it for an extra fan, if I use it at all.
