    SSD Install = Higher CPU Temps?

    Finally got around to installing a new Samsung 850 EVO 500gb drive. What a difference! On my JX-TB71 I previously booted from a 7200rpm drive - the difference is night and day.

    Here is a screenshot of the speeds that Samsung software reports.

    I have "rapid mode" enabled, hence, the insane (reported) speeds. This eats up (up to) 25% of physical ram, but, no big deal since I have 16 gb.

    Interestingly, my CPU and MOBO temps are frequently higher now on the SSD install of Windows 7 compared to the HDD. Right now they are idling at 41/42 degrees C respectively - which is perfect, since I haven't repasted in over 2 years!

    However, this is now rare on the SSD install of Windows 7. I could be mistaken but the CPU fan is on more often than usual, and temps will spike faster and higher than they did on the old HDD install.

    I do a lot of video editing which really works the CPU hard, so this has me a bit concerned. And I can't figure out why the temps are higher now.

    My only theories right now:

    A) the new install of Windows is, new, so wait a few days and see what happens
    *B) I have the "wrong" driver installed for the CPU
    C) Rapid Mode from Samsung is driving the CPU slightly harder than normal

    *I say "wrong" only because it may be different than what I ran on the HDD windows install. Windows currently tells me that everything is up to date, as does Slim Drivers.

    Anyone have any ideas? I will disable rapid mode this week and see what that does.

    Finally, what do you run on Windows 7 for a G750?


    Thanks. Also, for what its worth, I did some basic searches and apparently this is not an uncommon issue for a new SSD install.
