What/where is AUXTIN1 on MSI z87-G41

My manual doesn't say anything about it. I'm assuming its a VRM. It's hitting 117c and my CPU is throttling. I'm wondering where to concentrate airflow.

NewEgg reviewer comments..
" I always give items a thorough inspection before use. I ordered 2 of these boards at the same time. On the first I noticed the heatsink on the Voltage regulators [The large one next to the CPU] was LOOSE! Easy enough to tighten the screws on the back of the board, but this could easily cause issues after install. "

" The design is awful if you have anything in the PCI slots. Southbridge is perfect for melting and the whole thing has a way of holding heat like no motherboard I've seen before. "

Oh. Well. I touched both and the southbridge is warm while the large one is cool. I do have a fan pointed directly at it though. I will test for looseness.

It might not be the VRM throttling actually. In order that is the core clock, iGPU clock, CPU package power, VRM temp, and temp of core 0.
Nothing has gone over 60c either.

Are the iGPU cores told to throttle at a certain power consumption?
