I agree about new alternative. I don't have problems with SpeedFan but i don't use hibernate either. Only downside what i have is that SF show only temperatures from my motherboard, no fan speeds or voltages. Sending reports to author have not help either.
My opinion from Core Temp is that it's way too limited, only cores temps.
Does anyone have experience from Lavasoft's Everest? I never tried it but I've heard it show very much info from pc.
