[Tutorial] How to make your 900 Series Video Card have a 0% fan mode!

[Lays]

Interesting Guide , I've never seen this sort of stuff into action 

I give your guide a 3.5/4.

Thanks buddy! It was an experiment people said wasn't going to work on ltt and on OCN, so I tried it and it worked. Then I whipped up this video spur of the moment lol.

@Lays Alright so I decided to check to see if it was my cpu. Apparently, f@h has discovered a small instability in my oc. I lowered my clock from 4.5ghz to 4.4ghz (kept the voltage the same because I'm lazy) and it ran all night and day. Thanks for the help anyways. Also, great tutorial.

I was holding my breath when i flashed my 970 g1 but everything went well. Now my PC is dead silent! Thx lays

Im using a modded bios with the 0db fan setting as well. The only thing i worry about are the VRM temps.

If the card isn't under a load it'll be perfectly ok, since VRM's will only get hot when power is going through them.  (Watching movies, playing CPU intensive games etc won't really do much to them, since the card only uses ~10-30 watts doing those tasks)

I'd imagine anything over ~60 watts would make them toasty, but the fans would turn on by then most likely because the GPU core would be warm by then as well.

This is exactly what I need.

 

I'm later this week going to order the Gigabyte 980 but I've heard that it is LOUD with capital letters.

Idk why Linus said in his video about the 980 that it was "pretty darn quiet". But in every review I can find they say that it's "loud" during load?

 

Is it a good idea to do this do a spanking new card? Or will it shorten the lifespan of the card?

 

And if you do fail this procedure how easy on a scale from 1-10 is it to load to the old BIOS that you saved in GPU-Z?

 

Sorry for all the questions, I'm a total noob when it comes to desktops since I've owned a laptop my whole life.

It's super easy to do, most of the people so far that have done it said they were nervous and they just followed the steps and it worked fine.

 

As long as you don't tell the fan to turn on when the GPU is like 80C, the lifespan will stay the same.  You may take like 1 month off it's lifespan but I doubt it, usually with 1 card & the fan off it'll idle anywhere from 30 to 55, so it's really not that warm.

 

If you "failed" the only thing you could do wrong would be losing power during the flashing process, or having a BSOD or a pc freeze for the most part, so it'll be OK.  And even then, if you boot into safe mode & uninstall nvidia's drivers, you should be able to reflash a bios on the card without any issues.

Ya it is pretty easy to mod bios with a little research  I like the 0% fan mode alot. It kicks in @ about 65c and my temps never go much past that!!! Great guide btw!!

So I did this fix, and am using the curve at the bottom of this page. Now my GPU sits at about 59 during general windows desktop use. And idles around 57.

 

Is this a safe temperature for around the clock? Should I change my curve?

Yeah it's fine or all the 970s that have 0db fan modes wouldn't have it in the first place, when idling if you have your monitor set to turn off after awhile it'll idle a lot lower as well.

[Dabombinable]

I'm going to try this as well with my GTX 970. Is it pretty much the same process with kepler (aka my GTX 650Ti OC windforce)?

I'm going to buy my computer this week.

 

I'm torn apart whether I should get the Gigabyte 980 or the Galax HOF 980.. The HOF edition will go nicely with my white build..

 

But I'm not sure if I can flash the BIOS on that card?

I might go with the Gigabyte one and just paint the backplate and the shroud white..

 

Either way will post here if it works when I get the time to try it out!

It'd work just fine with the HOF since it's still a maxwell card, but the HOF is quite expensive and really not that much better than any other 980/970 unless you plan on watercooling it.

So if you want to save a hundred or so bucks I'd say get the Gigabyte card and paint it like you said, it'd be pretty cool!

Well here in Sweden where I live. The HOF is only 300SEK(35$) more expensive than the G1, hell, even the HOF V2 is 200SEK(~24$) cheaper than the G1..

 

But I'll probably go with the G1 since I'll be unique!

I would try it with my GTX 750Ti but if I brick it I dont have the cash to replace it.

Unless your PC turns off in the middle of the flashing process, nothing else can really go wrong.

[blackadder]

Jo, my 970 G1 has pretty high rpms when booting. Does that fix that too or is this generally not normal?

its normal, it gets dust out, or so they say, I think it spins the opposite way. thats also fan speed 100%

Same Process but less likely to work I did it for a Asus DCUII 650ti Boost and it didn't work correctly.

[hecticassassyn]

I have 970 G1, fans still at 34. Followed everything and checked twice..

Did you make a custom fan curve?

Something is wrong then, because it shouldn't have minimums.

 

It should be like this:

Okay, guess I'll try it again.

[hecticassassyn]

Success! Thanks for the tutorial. Now only if I could afford a couple terabytes of ssds to replace my mechanical drives lol

[Addeuz]

I have a big problem..

 

I've flashed the BIOS and everything went well!

 

But when I start MSI Afterburner, the lowest I can get is still 25%..

 

As you can see here:

 

My fan curve:

 

And as you can see here, it still spins at 25% and 800rpm:

 

My MaxwellBiosTweaker settings:

 

What is the problem???

 

Sorry for so many pictures!

 

OH BTW!

There is a new nvflash version, I had to download that and then it worked!
