    So I think there may be a bug in Core Temp and HWMonitor showing abnormally high and low temps for mobile sandy bridge procs and am looking for others to test my theory. I say this because I have had some erratic temp differences with it sometimes even negative temps which I doubt since my pc is decently warm. Here are my temps for the same time period comparing Real Temp and Core temp. HWmon gives the same as Core temp also and it makes me wonder if for some reason these programs are reading from another temp sensor rather than the cpu or something. This is after a few minutes of gaming. You can also see core temp shooting one core at 100C and the rest at 50C [wut?]. It also shows my processor as a 2520QM when it's a 2630QM.

    A lot of people have been panicing about high temps and I think inaccurate readings are the cause for a lot of us mobile i7/i5 users.

    If anyone else has a SB mobile processor and wouldnt mind testing this out with core temp and real temp running, I would appreciate it.

    For CoreTemp, when I try install it, Windows Defender and Kaspersky IS 2011 report that it trying to download a "Hidden driver" (KIS2011), while Windows Defender report that it is a type of spyware/adware, so I dont think I will try CoreTemp.

    Although I use 3 different temp monitor which is Open Hardware Monitor, HWMonitor and Real Temp, and I found that Real Temp and Open Hardware Monitor doing great and very accurate, as for HWMonitor, not so accurate. I have no time to do the testing right now but I will update when I have time.

    HWInfo64 (not current version) displays everything correct. cputemp doesnt. it reads the cpu as 2520 too.

    I am mainly concerned with temperaturs though because using real temp I stay around 80 for gaming but I've had Coretemp say I hit 100C right after turning the darn thing on.

    CoreTemp hasn't been updated for awhile I've noticed. I keep looking for new versions because it feeds temperatures to the CPU status widget I like to use.
