A detailed overview of SpeedFan.
The different temperatures shown are from three separate cores, each displaying its own heat level. The CPU isn't a single unit but has multiple parts working together. The screen image you shared shows the current thermal readings for each core, which can vary depending on workload and usage.
core represents the average CPU temperature across all cores. The remaining three readings are merely random sensors located on your motherboard. It's hard to pinpoint their exact positions since each board differs. The GPU temperature is tracked separately via HD0 and HD1, which monitor the disk drives. Clearly, one sensor isn't installed or is not functioning properly.
