/NOSMARTSCAN fixed the problem for me.

I had this same freezing problem with Speedscan 4.47 and 4.49 on win8 64-bit with ASRock Extreme4 Z77 mobo and Intel Intel i5 3570K CPU. It froze consistently after the Speedfan status read "Scanning Intel SMBus at $F040...".

Old post with a new try.
I ran the following in command prompt with Speedfan 4.49, Windows 8 64 bit:
C:\Program Files (x86)\SpeedFan\speedfan.exe/NOSMARTSCAN

The following message appears:
ERROR<SPEEDFAN Driver Not Installed>
Is SPEEDFAN service started?
