[solved]Adjust fan curve in BIOS

[pat-roner]

Hey,

So I run a custom cooling solution on my 980ti, and therefore the stock fancurve is a bit off, and I currently use msi afterburner to have a custom fan curve set at all times. But since the only thing I use afterburner for, is the fan curve, I would like to just adjust the BIOS and flash the card.

Does anyone know how to do this? I can't find a guide on how to adjust the fancurve only.


And please don't bother replying with "why can't you just have afterburner running" - iknow I can (i have for two years), but would like to not.

I use MSI AB for my 980TI with Xtreme III set it at 33% get about 1500 rpm silent and it keeps the card below 65ºC. But even with the default fan curve it ranges from about 20-35% since the cooler is so efficient. But more info would help you like the exact model of cooler and the temps you get with it. Also flashing your GPU BIOS might void your warranty.

Don't brick your board. Make 2 copies of your bios, see if your card has a dual bios switch on it, get the manual specific to that model number of card, you can find the sku and model number via the white stickers on the board. Once you have that stuff get a bios modify tool for your series of chip/card, find directions on doing bios mods and proper flashing procedures, take 1 copy of the backup bios and modify it, change the name slightly so you know what is what. Put the mod bios and stock bios on same drive so in event the mod bios fails you can restore the original hopefully. Just remember card manufactures don't normally cover bios flashing/modification for warranty, they do check for that now too, so if it fails and you can't recover even if the card manufacturer sends you proper tools and directions, you might as well buy an upgrade.

DON"T flash the bios. Just like you said "don't say why can't you just have afterburner running" Then don't ask why not flash the bios. Just trust us here.

If the flash goes wrong, you have an expensive paperweight.

I also use AB everyday for the custom fan profile, I don't have any problem with that, works well for me!
Actually I'm glad I'm able to control the fan speed by software since I would not want to take the risk flashing(possibly bricking) or voiding warranty of my expensive graphics card.

I don't think anyone has ever figured out how to change or even decode the fan curve in NVIDIA BIOS

normally if ya look after maxwell II bios tweaker tutorials there is a section(videos are long) for custom fan curve and the rest ya need for flashing
like this:

How to flash Maxwell GTX 9xx bios - Step by step

or this: look at 1,35min
https://linustechtips.com/main/topi...your-900-series-video-card-have-a-0-fan-mode/

you get the idea

and what wizzard said\there is even a "experimental" tag in fan settings from maxwell bios editor

 

[W1zzard]

maxwell bios editor

It just lists the raw values, which isn't really user friendly. Have you seen any analysis on how these values actually work?

 

[eidairaman1]

What the rest said, you'd be better off running afterburner and save yourself the headache and money.

Okay, so i tried to edit the fan values in the BIOS with the editor (used the LN2 bios on the card), and things went haywire. It seemed to work fine at first, but after a couple of minutes of GPU load, the pc froze and had to hard reset. So I ended up just putting the LN2 bios back in place and continue to use AB. Thanks for all advice guys.

LN2 is for liquid nitrogen benchmark runs only.

Isn't it just another BIOS for LN2 runs? Or does it activate any hardware features of the card that is not present in the regular bios?

It's just for Ln2 runs, if cards were like the 9500 Pro or x800 back in the day, then it would unlock features.

I suspect the reason why you froze is the voltages caused overheating or not specifically for you card. You are better off taking your stock bios and modifying it, however that is a difficult task as @W1zzard stated. So its easier to use afterburner.

I remember using ATI traytools to do ocs and it used little resources.

Tried that as well after trying with LN2 bios, and it was still not stable, and froze :/

Well as you said yourself run afterburner and enjoy your card.
