If the VRM heatsinks were loose on my motherboard and I was told that was normal for the model of motherboard I'd purchased, I would exchange it for a different motherboard.
For heat to be transferred from the VRM's to the heatsink, the heatsink must be secured to the VRM's, if the heatsink moves easily, then the transfer of heat will be inefficient if not outright non-existent depending on how loose they are.
Thanks for the suggestion, I really appreciate your help. The motherboard seems to be doing ok right now in terms of temperature, but somehow my 4790k is reaching 90 degrees in crysis 3... Thats with a noctua heatsink. My old 8350 didn't even go above 55 in the same game and I thought the AMD cpus are suppose to heat up worse than the intel ones.
