Ok i registered on this site to help you guys out with the overheating issue for the Zotac GTX 460. Ok so to start off watch these youtube videos they will explain alot better than i can so gohead and watch these videos.
watch all his parts from 1-3 and then the fermi editing video. I also forgot to mention if you are running sli i will recommend flashing them seperately.


the last video shows how to use the fermi bios editor. Ok to start of im going to provide you guys with a link with all the files that you are going to need.
http://www.mediafire...5fbdyad2cnh55pg
After you have downloaded the files make a bootable usb stick as shown in the video. Then when that is done copy nvflash onto the drive. After that is done extract you bios using Gpu-Z that i have provided in the download link. Save it onto your desktop and open it with the Fermi bios editor from their you can edit the voltage settings and fan speed I have mine set at .987mv and the fan speed is set at 40 percent minimum and 100 percent as the max. You can also set your overclock settings but i wouldnt recommend it. When your done setting your voltage settings and changing your fan speed save it onto your desktop. This time it is going to save it as a .rom file. You need a .rom file to be able to flash the card using nvflash. Once you save the file copy it into the bootable usb stick. And then restart your computer. Make sure to select your bootable usb stick in the bios to boot from it. Once your in dos with your bootable usb stick type this in nvflash (your bios file name).rom and then hit enter and then (y). After its done flashing the new bios its going to say bios verification succesful. Then press CTRL ALT DEL to restart your computer do not turn it off as this can corrupt the bios. Go into windows and check if you can raise your fan speed and if your overclock settings are showing up on GPU-Z. I have my cards running at stock clocks and modified voltages and fan speed. My cards never hit over 90C they use to go over 99c when they were in sli now the top card runs at 88c full load and the bottom card runs at 78c full load. Tested using furmark. Hope this guide helps anyone having the same overheating issue as i was having.

Quick note: I am also using msi afterburner for a custom fan profile. I have it set to use user defined fan control. That way my fan increases its rpms faster than what the card is designed to do. So i will recommend installing afterburner and using the custom fan profile just go to the options menu in afterburner and go to the fan profile tab and just check the enable user defined fan control option and you are good to go.

Please do this at your own risk.
Zotac does not support or recomend reflashing the BIOS.
If you need to RMA your graphics card it will have to be returned to stock settings.

Thank you I used this technique to remove the 70% fan speed cap. Thanks for packing this all up very handy. Note that you can change the voltage in AfterBurner just unlock it in the settings.

your welcome im glad i can help out and Yes you are right about the voltage control option in msi afterburner. The only reason i mentioned it in the post was if the users wanted to embedd the changes permanently into there cards without using afterburner. So thanks again for the reply im really glad that this guide helped you out.

Thanks for the tutorial, I'll be sure to perform the fix once I get my hands on a usb drive. I do have a few questions though.

First things first, how loud is this thing going to be with fans at 100 percent? Am I in for a hurricane when it cranks up or is it tolerable?

Any clue how dangerous is it to have a 460 GTX with temps reaching the 90c mark? Mine has hit around 91c after playing a mission in Brothers in Arms: Hell's Highway recently, which caused me to stumble upon your guide while searching for a solution. I'm interested in knowing since I'd like to continue playing while waiting for my usb drive to arrive, but if the card is in imminent danger I'd rather not risk it and could just use my 9600 GSO in the meantime.

Lastly, I'd like to ask about your modification of the cards stock voltage settings. I'd assume lowering the voltage would net lower temperatures while bringing the need to lower clock settings for stability, correct? Should I lower it down by steps of 5-10mV (my stock voltage is showing up as 975mV in MSI Afterburner right now, though I can't lower it with the program itself as attempting to lower or increase voltage merely causes to the bar to snap back to default) and see how temps respond until I reach a good compromise for performance? I also noted your voltage increase to 987mV, is it necessary to increase voltage for the higher fan speed or was it for another reason? Thanks in advance mate.

Hello Final Justice i just want to let you know that their are two stock voltage settings for the Zotac Gtx 460 Cards. I have two of them in sli and one of my cards stock voltage is at .987 and the other card the newer one is at .975. So im guessing you have the A2 bios version and not the A0. Ok to start off about your question regarding the fan noise. Trust me on this it is not that loud at all since your temps are around 91c my guestimate should be that the highest your fan is going to reach is %85 after you have flashed it. And it will keep the temps down in the lower 80c. And your fan is going to idle around 40% when its on idle or whatever the minimum fan percentage your going to put for your card. I will recommend using 40% since it is the default setting for the old zotac gtx 460. For the new Zotac Gtx 460 the minimum fan speed is set at 20%. Ok the answer to your second question no the only reason i did the voltage increase was because my cards were actually unstable in Sli due to the voltage differences in both cards. So thats the reason i upped the voltage of the new card to .987 so they can run without giving me any hangups. And if msi afterburner is resetting your voltage anything lower than .975 is not going to work for your card and it will cause it to freeze during gaming. So id prefer when you are flashing your card to not mess with the voltage. I only recommend that option for people who can run there cards at lower voltages with stock clocks. if your card cant handle anything lower than .975 at stock clocks then dont mess with the voltage setting. Also 91c is completely reasonable temp for your card but i will reccomend flashing it because it will drop your temps siginificantly. Also i will recommend using msi after burner for a custom fan profile. Ok i forgot to answer one more question here it is, you dont have to mess with your voltage settings to increase fan speed. When you are flashing the best option for you is to not mess with the voltage settings at all since your default is .975 and it wont let you go any lower than this and also to change your minimum fan speed to 40% and maximum to 100%. Make sure to use msi afterburner and just select enable user defined fan control and thats it. I assure you that your fan is never going to reach 100% fan speed. My cards are in sli and the top card reaches 80c while gaming and using furmark it reaches 90c. So Good Luck!

Are people actually looking at this post and asking for a bios update there isnt going to be any official bios updates from zotac you have to extract the bios yourself and edit the settings

[notacustomeranymore]

so how does it fix overheating issue?

you flash it and declock it or what?

[Thenician]

Suppose I'm not the type to confidently mess with bios settings. But also suppose I'm tired of having to keep my case open with a box fan strapped to it because this card is garbage. What would you suggest then? What card can I just cram in my case and forget about?

[Thenician]

Nvm, apparently it decided to burn out again. Time for another rma.

Hi,
i have a gtx 460 which freezes up during game play. i have to manually restart the pc after this. during gameplay the temop goes beyond 100c !
the fan speed is at 800 to 1000 rpm. can i use msi afterburner to reset the fan speed?

Wow, your card should not be getting that hot, vivek. If you can, please get it replaced as soon as possible either from the vendor you bought it from or through ZOTAC directly. If you are within the warranty of your vendor, you can RMA it through them. But if you are past that period, and are located within North America and would like to get this handled through us directly, please follow the steps below:

1. Please create a user account on your website: http://www.zotacusa....ustomer/account

2. Then, Register your product so we can determine its origins: http://www.zotacusa....egister/product

3. Then, submit an RMA Request so we can evaluate and process your request. http://www.zotacusa.com/register/rma

4. After that, you will receive an email with the outcome of your RMA Review.

Thank you

hey guys
i just created this account so u may help me with my GTX 460 SE
so what happened is that i start the PC with 38-41 Degree after i start a game it jumps to 91-95 Degree after while it just stop working and the pc restarts so i messaged Zotac about the temps and they told me its not that high !!! so i knew they wont help me with it and i dont have a warranty so i started looking for solutions and some people told me to change the thermal paste so i did that and now the IDLE temp is 78 and the pc stops working after seconds of starting a game so i think the new thermal past is bad so i want to ask you what should i do ??? should i get a new and better thermal paste ( the problem is that i live in a country that does not have anything but if u can give me the name of the thermal past i will try finding it ) ??? and if i do this reflashing will it help me or not plz am hopeless and i need someone top help me with my problem and thanks alot

Hi ShadiGhabboun,

When applying new thermal paste, were you sure to not get any on the PCB? Did you reassemble the card correctly? What software are you using to monitor your temperatures?
