MSI GTX 660ti OC PE (Twin Frozr) weird fan issue, Please help :)

[Toxicnitr8]

Hello all   ,

 

Thanks for having a look at this issue , 

 

Ok, so I have 2 MSI  GTX 660ti OC PE cards in SLI , 

 

Both cards have been treated exceptionally well , dusted regularly and only very minimally overclocked. 

 

The problem I am having is that on one of my cards , both fans will start at boot up , completely normally for about 3 seconds , no grinding/whining sounds , nothing , but then all of a sudden the one fan will power down , and will twitch every now and then as if it were trying to power itself on , I have even had it where both fans will turn off .

I got MSI Afterburner to mess with the fan speeds and see if I could get it to spin , and as unless I set it to 80 percent or higher it will not spin up at all , It seems like some kind of power saving feature ,

Like its idle fan speed has somehow been set to 0 ,

because at the higher temps as long as my fan curve is set right , it will turn on and cool the card normally, the fans are pretty loud at 80% though especially since it goes from 0 - 80 the noise difference is really bad . but as I said before the fans are in great condition , and spin very freely when spun manually . 

 

I have tried flashing its bios using a backup of the bios on my other card , I have tried using it with different power and PCI slots , 

 

I am a DIY kind of guy , and warranty is long gone , so I am open to the idea of opening the card up completely , but I have no idea what I would be looking for . 

 

any ideas on what might be causing this ?

 

Any one else having this issue ? 

 

I really appreciate anyone who takes the time to read the essay above

 

Thank you
