This is the part that's overheating.
Since installing the new motherboard in 2016, I've experienced unusual high temperatures (check screenshot). Initially, it seemed manageable, but now I'm concerned it could affect the longevity of my system. Even with years of experience, pinpointing the exact issue is tough—Open Hardware Monitor doesn't reveal the cause. My old MSI K9N Neo V2 never showed these spikes, so I suspect the chipset might be overheating again. There was a recent internet glitch and app crashes that resolved after rebooting. The specs look normal, but the heat is a red flag. Should I be worried?
It seems like a sensor problem, but if it appears on another hardware monitor, reapply more thermal paste.
Identifying a bad or unused sensor is easier when the measurement stays the same.
I got HWinfo after installing it, and AUXTIN1 was the one showing the highest temperature, changing between 115 and 120°C based on my activities. Around 20 minutes before I started overclocking my graphics card, my PC froze. I initially increased the fan speed to its maximum as usual. Before adjusting the OC settings, the system would only let me pick desktop icons and then freeze completely. After a few Ctrl+Alt+Del presses, it recovered. I opened the Open Hardware monitor since I hadn’t installed HWinfo yet. The sensor labeled AUXTIN1 was reading between 119-120°C. Once I downloaded HWinfo, the temperature dropped a few degrees and now sits at 117-118°C with full GPU fan and core OC enabled. It’s currently at 116°C while I’m writing this (the card is running at default settings since I’m not gaming or testing anything). AUXTIN2 appears unrelated to this issue but operates between 110-113°C. It seems the motherboard’s DC-DC converter chips might be getting hot. Also, running Furmark with both normal and max fan speeds cooled AUXTIN1 to 114°C. These readings are confusing, especially since the voltage on the 12V line dropped from 12.495 to 12.233V when the card was drawing extra power at full speed. The low-voltage lines also showed minor fluctuations in that range.
