Palit is preparing at least two models for the upcoming announcement. The first model is called Dual Fan and it features the same dual-fan cooler we already saw on PNY model yesterday.
The JetStream GTX 1070 Ti comes with much bigger, RGB-enabled dual-fan cooler. This appears to be based on custom PCB with non-reference power design. A straight copy of GTX 1080 JetStream? Well, it seems so.
