ASUS ROG Strix GeForce GTX 1070 – Upgrade 2017

I had bought the Gigabyte Windforce x3 OC 2GB Nvidia GeForce GTX770 (GV-N770OC-2GD ) back in 2014 when I built my Mini ITX gaming rig.

Recently upgraded my case to the Phanteks Enthoo Evolv ATX Tempered Glass case and had fallen in love with the temperatures all over again of a tower case. The fans were being controlled by the in-built fan hub which went off the CPU temperature. However, having a Corsair H100i AIO water cooler mean’t that I didn’t have to worry about the CPU temperatures all that much. Whenever I played games the temperature which rose the most was the graphics card temperature – up to 78c.

I came across the Asus Strix series a few years ago when they had introduced the 0db gaming and so wished that I had purchased one of them back then. Kind of glad I hadn’t back then though! In this new series of Strix cards they have introduced two 4 pin fan headers.

As you can probably guess by now, I was aiming to go for complete 0db by purchasing the ROG STRIX-GTX1070-8G-GAMING to replace the

You can hook up case fans to these headers – ideal for case intake fans. They work off the graphics card temperatures and can be controlled by the GPU Tweak II software which ASUS provides. You can use the fan headers without the software but what you would be missing out on is the ability to create custom fan curves independent of the graphics card fans themselves. By default the 3 card fans and the 2 additional headers turn on around 60c to cool the card. I have not managed to figure out whether the 4 pin fan headers are actual PWM or just Voltage controlled as I have plugged in both 3 and 4 pins and they are controllable still which is good!

I have set two intake fans with a splitter to go on one header and a single rear fan exhaust in the other header. My plan was to have no fans spinning whilst the graphics card is not under load.

The CPU is set to exhaust via the H100i radiator on the top of the case – those are controlled by the Corsair Link software and dependent on a custom curve of the processor temps.

With this setup, I have no moving fans other than the CPU fans spinning at 400rpm~ when idle. On load, to my surprise, the GTX1070 doesn’t even hit 60c! whilst playing Overwatch on Epic settings for hours. It spins up a few times though when the room ambient is a bit high and it does hit 60c – doesn’t take long for the fans to ramp up and drop it back down to a 58c’ish though.

Wouldn’t really call it 0db rig entirely as the H100i pump still makes noise 😉 BUT! it’ll do for now.
