    Any way to flash back to previous EC firmware?

    Since flashing to BIOS 211, I've noticed that the VGA fan ramps up at 85 C, which is fine if I have to live with it but I'd prefer to have the EC vga fan settings from BIOS 209 and earlier that let the temp climb a bit more before revving up the fan. Any ideas or documented ways to safely do this?

    I've already flashed back to BIOS 209, but this didn't help. Should I try to flash back to 206 and then to 209, etc. to get the old EC settings back?

    You should be able to use the EZFlash in BIOS to roll back with no problem.

    Yep! Doing a rollback with EZFlash bricked my G73JH no problem. Did it quick and efficiently!

    obviously your unlucky... anyways , doing BIOS flash in G73 is risky whether forwards or backwards... its actually safer in EZflash... anyways , i guess u didn't do it properly or were just very unlucky...

    Yes, it's true, bricking can occur, and let me tell you how many times during beta testing that I flashed the BIOS... and never bricked once, fortunately.

    @&lt;MarkS&gt;: did you flash from a FAT formatted USB stick or your NTFS partition on hard disk?

    (Forgot about this thread, but I still want your feedback)

    I guess I wasn't clear in what I had done. I had already successfully flashed back to 209, but it appears that this doesn't update the EC/fan settings, since I am now on 209 but still stuck with the 211 fan settings.

    Pro-tip: Never EVER flash BIOS from hard-drive (unless you're usin WinFlash for some weird reason).

    Is his case an isolated incident or is it normal? Once you upgrade to 211 you are stuck with the higher rpms? Even if you reflash to 209? I was going to flash to 209 just to see how it affected my temps. But if the fan setting stay at 211 settings, why bother.

    Yes, this is my exact dilemma. I'd prefer silent fans all the time, even if my max video temps go up to 90C or so (I've repasted, so my max right now is 85C under the BIOS 211 fan speeds, even though I flashed back to 209). The fan always kicks into high gear at 85C (happens after 1-2 hours of gaming) and so it never really goes above that.

    EDIT: After reading the new Chastity Repaste thread, I see that BIOS 211 fan ramp up is at 77C. If so, then my current ramp up at 85C is most likely according to BIOS 209 specs. Anyone that can confirm this? If so, I can just let this drop.

    That's 77C Core temp (Tss0), not MemIO. Just make sure 85C is from Tss0.

    Thanks for everyone's advice and help. I've verified with GPU-Z that the VGA fan doesn't go full blast until ~85C, as I've read all sensors above 77C and the fan didn't kick in.

    At any rate, looks like flashing back to BIOS 209 will indeed give the correct 209 fan speeds and not the crazy 211 fans.
