Is there something wrong with it?
Speedfan reports a ton of temps, not all of them are valid. If it never changes I wouldn't be concerned about it.
Indeed, I also have 2 stuck sensors.
You can test sensor movement with real temp if you want.
If you want accurate CPU temperature readings I would suggest to you to download CoreTemp, it gives far more accurate readings since it reads the temperature based off of the CPU dye like your BIOS does.
