Core-Temp shows weird multiplier counts on Core i7 930 3.4ghz

Hey guys I've OCed my processor to 3.4 ghz on 1.13v cooled with Corsair H50.

- Core Temp shows a weird multiplier count [note: Alternative speed detection method is disabled. Enabling it makes no difference.] (see below)
- I have C1 state enabled (multiplier should be reduce during lower loads
- Real Temp reports a multiplier of 20 instead of 21 on a minimal load
- Speed Fan shows a hot icon on "Temp 3" which I have no idea which component that is



I would appreciate if someone could answer my observations above. Thank you.
