    You can always connect a temp probe to the mobo-pins next to the OPT fans. And just connect the temp probe to the gpu. And done

    That's a good idea...I guess I can buy a temp probe cable but can you control OPT fan or chassis fan temperature by temp probe though? I don't see that option in Fan Xpert or in BIOS?

    What board are you on? I'm on a Maximus V Gene atm. and that doesn't have OPT fans.

    If you check under opt fans in fan expert, you'll see that the temp indicator is not moving at all, since there is no temp sensor connected to the temp header. Will check back when I'm on the Extreme board.

    I have the Maximus VI Formula..I guess I can connect the GPU cooler fan to a chassis Fan as well but can I actually control fan speed then by temperature probe? I don't see that option as being even possible in BIOS or Fan Xpert 2. Also, where should I attach the temp probe to the GPU? I am assuming the back of the GPU?

    Hmm, it's hard to explain. If you have a look at the image below. The yellow dot with the HUGE red arrow is the temp.

    If you switch to a OPT fan the temp dot will not be moving at all(I think) When you connect a temp probe it will start moving.

    Yeah the back will probably be fine, it doesn't really matter if you don't get the exact temp as long as the temp increases like the gpu temp does.

    Good to know, I will give it a try when I get a thermal cable. Still won't control chassis or CPU fan by thermal cable though, I think those fans are control by onboard temp sensor? Also, in Fan Xpert 2 I noticed I don't even have the ability to change anything like Chassis or CPU and CPU_OPT fans, only time I can change the setting is in BIOS and the temperature is pretty simple in comparison to Fan Xpert 2.

    The fan connectors that have 2 pins beside them, those are the ones that can be controlled by OPT temp.

    I have tried connecting temp sensors and the temp shows. I personally like a fan controller better but that's just my personal opinion.

    If you want to run another fan of the GPU's fan connector you can get one of these..

    Actually I noticed a weird thing...

    On the maximus v extreme in Fan Xpert 2: you CAN control the opt-FANS


    On the maximus VI extreme in Fan Xpert 2: you CAN't control the opt-FANS !!
    so any temperature sensors connected to the opt-temp1 - 3 will not yield any change in fan behavior.


    in that perspective on the z77 platform you have more controle over your fans, although I will have to check if the fan profiles behave according to the opt_temp sensor readings (I suspect the are all connected to the CPU temp).

    I think we should compile a list with what a tool like Fan Xpert 2 should be able to do and if there are any flaws!
    Please only serious reponses!
