Why do TMPIN labels look cryptic?

TMPIN traces map to motherboard zones such as socket skirts, VRM banks, or PCH neighbors so vendors can surface board-level hotspots beyond the CPU lid.

Q: Will HWMonitor expose GPU power rails?

When the silicon exposes it, HWMonitor lists slot draw plus supplemental PCIe power in watts, including brief peaks during transient loads.

Q: Which CPU temperature row should I trust first?

Start with the package average because firmware throttles against it, then scan per-core peaks to catch paste spread issues or blocked cold plates.

Short, factual notes on the readings people argue about in forums.

HWMonitor reads the same on-die diode feeds your card firmware uses, so spikes line up with OEM tuning utilities—not synthetic estimates.

When the silicon exposes it, you will see slot draw plus supplemental PCIe power in watts, including brief peaks during transient loads.

Those traces map to motherboard zones—socket skirts, VRM banks, PCH neighbors—so vendors can surface board-level hotspots beyond the CPU lid.

• TMPIN0: chassis or inlet bias
• TMPIN1: socket / VRM neighborhood
• TMPIN2: auxiliary rails or legacy northbridge probes
