tomahawk max

Oh my, where do I start... I think I looked through every single post on this problem and still didn't find any solutions so here I am. Just upgraded my mobo, cpu and ram (prev. mobo - msi Z77A-G43) all went well, I posted and wanted to update bios and all the drivers, but there was no Ethernet...

I researched about overclocking and come up to this question, when you OC does it downclock & undervolt when idle? or it only activates OC when gaming/load? I have R5 3600 & Tomahawk Max and I plan to overclock it, Thanks!

Hi, I am deciding between those two motherboards. From my point of view, these are the main differences: The Tomahawk is ATX, while the Mortar is mATX. Would the former be better in terms of cooling/airflow because attached components would be more spaced? The case will be the Phanteks P400A...
