Hello,
 
My GTX 970 has been making an irritating chirping noise at idle since day one. It doesn't happen all the time. Initially, I thought it was coil whine. I just discovered that it happens when the fan is attempting to move at idle. Please see video of fan attempting to move. Is this normal?

maybe something in the fans PCB that controls that  [fans speeds ]    I replace a few GPU fans  for what ever reason  and its been in the fan    and to add they been power logic  fans at that..   seems like power logic is what EVGA uses  ..
 
you couls try a gpu fan  to test with   or  like you say when the -0- fan deal is activating  or trying to  just  set up a custom fan profile  with some fan software  [look up how to's ]    and set the fan to run full time or at idle at say like 20%  speed 
 
a lot of guys never liked the -0- fan option of these later cards and just did that 
 
now if it chirps  when running  maybe a dry bearing ?  look up how to lube case fans  and give that a try 
 
maybe the chirp is so minor like sajin said he did not hear it   and your cards not over heating and the fans do spin up as temps rises   just grin and bare it .
 
evga don't offer replacement fans  and the evga fans on e-bat are not so cheap as fans  go [wonder why ? ]    last card I just pulled a fan from a hd 6850  [ non power logic]  and scabbed it in where a junk power logic was  .   had to use super glue in place of screws  and the 6850 fan was a tad smaller size but the card work fine and dandy and runs and cools as normal and expected  to this day ,  and you'd never know it was swapped out unless you took it apart to see   
 
or see if its a issue to you if evga will RMA ?

don't know ?  the twitching seems normal  in that -0- fan mode  . lots of posts on that in forums around  asking this [any brand ]  .  some say theres twitches   some say theres don't , but the cards cool normal  and fans do speed up when the temp threshold  is reached . [60c +/-  ]  .

now the chirp ?    hard to say with out hands on right there .    maybe something in the fan motor ele. or mech.  that causes the twitching in some cards and not others and yours adds the chirp ? 
 
these fans are  serviceable    I looked at my powerlogic fand from cards  and there is lube hole in  to oil the brg.  easy   / no plug but some kinda tape covering the hole ?  maybe to prevent you from getting oil on the fans PCB  that is what controls the fans action from the cards sensors .   most folk tend to blame the card at fault  99% of the time its in the fan electronics  and most times just needs a good known working fan in replacement  not replace the card
 
heres a powerlogic fan  with a look under the sticker .   bearing under the black tape cover thing  and some of the exposed PCB of the fan
 

 
 
no bios switch then like I say do / try a custom fan curve profile .   [example]

I don't know why my phone mic won't pick up the chirp but it's definitely present when the fan attempts to turn. Is there a bios to get rid of the zero fan mode as my 970 doesn't have a switch?

I'll upload a modified vbios that has 0db mode disabled for ya if you tell me what the part # of your card is.

Thanks that's great news but I have a few questions:
 
1) Will this invalidate the warranty?
2) Will I be able to revert to the original bios if I'm not happy?
3) Will you be able to mod it so that it runs at 10% (450rpm) instead of 0rpm until 60 degrees celcius? Any higher is just too noisy at idle.
 
My card is 04G-P4-2974-KR.

Sajin
1. Yes, but you can always flash back to the original vbios before sending the card in for service to keep the warranty intact.
2. Yes.
3. Yep.
 
Here is the modified vbios... http://www.mediafire.com/file/5xvhj9nlyycdy4i/gtx970.rom
 

Thanks Sajin for the bios. I noticed you set the profile so that the rpm starts to climb at 30 degrees C. I think this will be noisy since the card idles at around 40 degrees C.

Sajin
Sorry about that. I uploaded the wrong one. This one is the correct one... http://www.mediafire.com/...iz0r3e8bblk/gtx970.rom

I think in this one PER01 should be 10.

Hey Fadsarmy, 
 
Sorry that your fans are twitching constantly like that, that fan behavior is definitely not normal. A vbios would not necessarily fix that issue.
 
Upon checking your account it looks like both GTX 970's that you have registered are within warranty, open up a support ticket on the card with the fan issues. A RMA for that particular issue is definitely recommended. Our EU support team will take care of you. 

Thanks JoseC. I will do just that.

Okay.

I managed the mic to pick up the chirping noise as the fan twitches if you set your speakers to high.

I heard it that time. Looks like it only happens when the fans twitch. The chirping may be normal.

like said probly  just another powerlogic buggy fan  . not hard to understand  here anymore with them .  pretty much told your options  -  live with it - adjust the profile  so it runs full time at a low rpm at idle  -  service the brg [??]  make sure the blades aint hitting something like the shroud or the wires ?- replace the fans  - Rma the card .
 
heck may run the fans full time at say  1800-2000 rpm for a hr or so and that may loosen it up  or cause something to ware in then mite work properly after that ?
 
''Weird thing is that it only twitches/chirps after a cold boot. If I restart the pc it stops''    see  for me I would lube the brgs  to be sure there not sticking cold  due to lack or dry lube , but that mat void the rma if you then decide to do that  if they were to look 
 
in the end all you can do is what TOU feel is best .;/
 
 
 
 
good luck 

pretty cheap here if you wanted to try as I said above ? 19 bucks
 
''Perfect replacement fans for EVGA 980 Ti SC ACX 2.0''   so should be for the 970 as well , but your call

or shop around   ,  here so far them powerlogic fans been short lived   and replacing them the cards are still going and cooling fine as normal ..  
 
even if you don't try you just don't know   and may work out and resolve 
 
I'm betting its in there fans PCB goes bad and causes these thing to occur  . so far its never been in the card itself  or the card to be at blame 
 
you can see the fans PCB in this I took   the replacement fan for it worked great in the card it was pulled out of . you know there using all high quality JAP components [ lol... ]  
 

 
good luck   
 
 
sorry I did not see /think about  I all ready posted all that above

I thought you said  your first ''good'' card just had that fan issue  not coil whine ..   that just gtx 970 for ya,  the #1 complaint of that line  from any brand . I mean coil whine and 970's went hand in hand  , that's been well known 
 
well sorry   and good luck 

You can send the replacement back.

Sajin
You can send the replacement back.

Thanks Sajin, that's what I want.
