    Team,
    I thought i would post an unexpected result of my BIOS upgrade from 901 to 1301.

    My MB temps went down by 3-5 degrees Celsius with the same OC (100x50). I am using Coretemp to keep an eye on temps.

    I am running a 7700K Kaby Lake processor.

    might be due to the performance hit caused from the Spectre and Melt Down patches

    That's really hard to spot. From 090x to 1301 there were a lot of changes (MC updates two times, yes)...

    Since it strongly depends on kind of CPU workload concerning Spectre and Meltdown patches and OP has not posted what temps they are....Prime95? Idle???

    3-5 degrees difference between hot summer day and wintertime is normal as well with air cooling...for instance...

    I do not think Spectre and Meltdown patches would reason a lower CPU temp....

    The CPU has to do usual work, but more steps at the same time to complete a certain task and hence there is a performance loss.. (loss of efficiency)

    It just makes common sense that if the cpu is running at a lower capacity, it will run at a lower temp also

    Point taken. Concerning capacity you are right. Furthermore if they disable branch predictions at certain cases...

    It would be interesting to know if CPU load includes predictions...and if disabled if you'd reach again 100% at all...
