Wow, I haven't touched my Hero board yet to check it out. It would be suck to not be able to use it at full potential. I have a paper due tomorrow so don't have time to test it yet, but I do hope that it will run fine though. My Asus Z97 AR board is running quite hot with the i7 4790K for now, without Turbo boost, it's already at 90C most of the time, some occasion hit 95-98C. The stock cooler seems to absorb the heat since it's hovering around 40C (it should be closer to the temp of the CPU, right? Just weird!). In my previous setup, I tried reseat the cooler 3 times but it's always 27-28C on the cooler. Seems like there are problem with the IHS which may have a gap so heat cannot transferred out efficiently.
After tomorrow I'll check the Hero board out and see what's gonna happen.
