Wow that's just pretty frosty - I thought you were overclocked and maybe looking at the wrong temp value somewhere, but that doesn't seem to be the case. Have you got a really cold room or something?

Not exactly sure what orcvader means. Core temps are not fake as such. They can potentially be pretty innacurate at low temps because the values are derived from digital temp sensors that are only calibrated to be accurate at TJmax so that the thermal protection kicks in at exactly the right temp - they are not intended to be used as measurement sensors and the further away from TJmax you get the further out they could potentially be. The TMPINx values are derived from 'proper' sensors but they will be on the mobo so will always read a fair bit lower than the core temps. I'm not sure which will be the CPU temp though.
Looks like you've just got a nice cool rig.
