I like JayZ's brutal honesty in that EVGA really does need to change the stock radiator fan configuration. Currently, it is hard controlled by the thermostat on the pump and there is no way for the user to manually change the fan curve whatsoever. Only the blower fan can be controlled by the user through a 3rd party tool (EVGA Precision OC, MSI Afterburner, etc). He proved that having said control over the radiator fan can have a huge effect on temperatures - almost 10C in fact, which was just amazing to me. All he did was replace the stock EVGA radiator fan with two 3rd party fans (push/pull configuration) and connected those fans to the motherboard and set the BIOS to control them. Temps dropped from 51C to 42C...and yes those temps are from testing under full load benchmarking
Sooooo, I do hope that the EVGA engineers are taking note and will make this happen in a future Hybrid version. Two other improvements I could see being added are 1) use of a 140mm radiator in place of the current 120mm radiator, and 2) option for Quick Disconnect fittings so that the Hybrid could be more easily integrated with other AiO cooling solutions.
I do have to give big kudos to EVGA for the overall design of the new Hybrid. Going with the FTW PCB and 10+2 voltage stepping has proven to be a great design decision. And the new Hybrid runs super quiet thanks to the replacement of the standard blower fan with the new propeller type fan. And those two 8-pin PCI-E power connectors weren't talked about very much by JayZ other than that he thinks it will help provide more stable power during clock boosts. No mention of it directly contributing to higher overclocking. I guess time will tell that tale
My EVGA GTX1080 FTW Hybrid arrives later today and I will provide more feedback once I have had a chance to test it out over the weekend.
