Hi, is it right ?
 
FAN 1 : GPU 
FAN 2 :  MEM
FAN 3 : PWR
 
That was I was told before but here's what I read on HWINFO:
 


Thanks

    Since you own the card just adjust the fan speeds via precision x1 to figure out exactly which fan is which.

    I did exactly that, Sajin, and found that even precision can't make up its mind which should be which. This may not be affecting anyone else, but when I was adjusting fan speeds to determine which was which, precision would take FOREVER to initiate the new setting, and it almost looked like it was cycling through all the fans and adjusting each one at a time. At one point I raised the speed up on "fan 1" and it was clearly the small vrm fan. My case was open and I could clearly hear that little fella going full tilt. But then I tested the others and wasn't seeing/hearing the one I was looking for, so I went back to "fan 1" and now this time I was the radiator fan. It was at this point that I decided to take the radiator fans off of the cards control, because my whole reason for doing all that was to try isolating an issue I was having with the "aggressive" fan curve be too weak and Precision being too unreliable to actually keep even that setting active.

    I hope this user has better luck than I did.

    Another crazy thing about Precision, is that in the custom fan curve tab the individual curves are not even labeled/numbered. On the temperature tab it will say fan 1, 2, 3 etc, but on the tab where you adjust the curves they all just say fan speed with no number. Such a simple thing of properly identifying the fans and having them labeled seems like a pretty big programing oversight.

    I just had a thought about this and wanted to run it by you.....
    Is it possible that whenever Precision loads its fan settings, that it is reassigning the fans each time? Maybe this is done in order, but not necessarily the same order each time?
    I remember when I was testing the curves that at times I would hit the default settings button just put the other curves back to default while I tested the next fan. Is it possible that this is what cause the issue I experienced?

    Not sure as I don't use precision much myself as it seems to be pretty buggy. I stick to afterburner myself.

    The only problem I get with afterburner is the memory only goes up to 1500 unless there is some way to get it higher ?

    Sounds like a job for afterburner extreme, or galax xtreme tuner.

    I still think it's a firmware problem .
    Ask evga for the latest firmware for bios's and try those.
    They will send them along with bios self installers if you ask
    Take a day or 2 .

    This is known.  Only PX1 can control all 3 fans.

    How you even can determine fans as "GPU - MEM - PWR" ??
    I don't get it. AFAIK FTW3 just has 3 fans on a single radiator. So all 3 fans ar cooling gpu because the only thing this big ass radiator touchs directly is gpu die. You cant say "fan1 is gpu" - every fans is "for gpu"!
     
    Both mem and vrm are touching single metal plate that transfer a little heat to the radiator via thermal pads in 2 points (front, near display ports and rear, near power connectors) and also cools off with air that went through radiator. So all 3 fans are cooling vrm and mem too. And you can't say that this is vrm fan because you have vrm in front and in rear part of the card. Also you can't, for example, stop 1 fan and say "Ok, I stopped fan 1, so my gpu temperature must rise while my vrm and mem temperatures will stay same", because every fan affects every component.
    So whats the point to determine fans on radiator?
    What is "small vrm fan"? Doesn't ftw3 have just 3 same size fans? What is going on here? *mind exploded*

    Each fan comes on at a different temp based off gpu, mem, or pwr. That is why the op most likely wants to know which is which.

    Hm, I thought that they should run on same speed since they are similar. If you are running similar fans on different speeds you can get really annoying harmonics.

    That's what the purpose is for all the extra sensors on the PCB, so each fan can set itself for each particular component it's linked to. I myself when had one always synced the fans at a manual speed though.

    best sound quality ... use the same RPM on all fans
     
    though the default "factory setting" will adjust each one as needed based on the temp of the section that controls that fan
     
    I find it better to run a Custom Curve
