I have never owned a Gigabyte mobo and have only used Asus. I really like the Asus mobo and have never had any sort of failures. I am sure Gigabyte is just as good and I have friends who have never had any issues with them.
I have a H100 and yes it is very noisy with the stock corsair fans. The noctua fans are much quieter and offer the same performance, however they are expensive.
Unfortunately no. This is my second Warthog HOTAS and it is starting to have some issues. Looking back I would have stuck with an x52 pro and saved myself the headaches
