Well that sucks that you sold it.... TechPowerup forum admins made my ZOTAC 1080 mini BIOS public & added it to the database after verifying it, and they told me that Pascal GPU BIOS modding isnt possible right now since you can only reflash a SIGNED BIOS, since they are all encrypted, so you can only sign another official card's BIOS, no modding of the actual 1080 mini BIOS is possible.... I even reached out to ZOTAC live chat support and was told that their support engineers are aware of that 37% minimum fan speed, but that they only work on BIOS updates for card ISSUES, not for feature requests. I was told to reach out to ZOTAC's social media pages in case their marketing team might listen and could talk to the product management team... but I knew that reaching out by myself would fall on deaf ears, so I took matters into my own hands, and so...
GOOD NEWS EVERYONE!...
Because I LITERALLY just figured out the 0% fan mod on my ZOTAC 1080 mini! It's SOOO QUIET NOW!
My SSDs are louder than it, heck even my CPU fan (Noctua A9x14) is louder than it... the fans are no longer limited to 37% fan speed (1170RPM) and they are now able to turn completely off. I have my ZOTAC 1080 mini's fans OFF completely until the GPU hits 55C, which it NEVER does when web browsing, watching 4K or UHD youtube videos, or even while watching a 4k UHD bluray rip!
How did I do it? I bit the bullet and did a BIOS reflash and it worked! I flashed my ZOTAC 1080 Mini's BIOS with the ZOTAC 1080 Amp! Edition BIOS...!
That card has a 0% fan mode feature build into it from Zotac called FREEZE, and I was right that this 0% idle fan feature was in the BIOS. And as such the fan limiter is UNRESTRICTED! But! Notice, the AMP! Edition card's BIOS comes with a SLIGHTLY higher base clock and boost clock than our 1080 mini does, so it might run a few degrees c hotter if you dont tweak your power limit properly,... but it's safe.
Here's a page with all the BIOS's for our ZOTAC 1080 series cards, including my 1080 mini bios in case you want to reflash back to stock.
Disclaimer: Reflashing your GPU BIOS could cause unknown problems, so do this at your own risk!
Here's what you need to know if you flash to the "1080 Amp! Edition" BIOS on your "1080 Mini":
- your 1080 mini will now be clocked 53MHz higher on the core old:1620 new:1683 (base) and will have a 63 MHz higher Boost clock on the core at old:1723 new:1822 (boost), totally safe since the 1080 mini can easily GPUboost 3.0 it's way up to 2050MHz in games
- Set a 0% fan curve at your own risk, even if the GPU core isnt hot, it doesnt mean other components arent overheating with the fans off
- I recommend you DO NOT set the GPU fan speed to 0% in your fan curve, as the GPU may need some sort of cooling on other components besides the GPU core, I'd recommend a minimum fan speed of 26% across the board (600RPMs)... this is a whisper quiet fan speed anyway. At 26% minimum fan speed (600RPMs) the fan will be stable, it will be WHISPER quiet at that speed. Why? Because if the fans are set below 26% minimum, the fan's dont seem able to maintain such low voltage and instead will turn on/off every 2 seconds.
- You should set your GPU's power limit to 78% (if you had it at 100% before), or 94% if you had it at 120% before... (in MSI afterburner), this is because the 1080 mini's original power limit of 217W is 78% of the BIOS I used to reflash it (which has a power limit of 276W), and you dont want your card going over it's power limit. so 78% power limit on the Amp! Edition's BIOS is the same as having a 100% power limit on the stock 1080 mini BIOS. and 94% power limit on the Amp! Edition's BIOS is the same as having the 120% power limit on the stock 1080 mini BIOS.
- untie your temp limit from your power limit in MSI afterburner, and Set a temp limit somewhere you feel comfortable, like 85c or 90c (just in case)
- I noticed that sometimes when on the 0% fan mode, the GPU fans would start up at a steady RPM for some reason, a quiet RPM, but MSI afterburner would still report 0% fans speed, so to avoid that glitch in fan speed, my fans are always running a 26%, which is 600RPM and practically silent.
Here's the tools and instructions you'll need to reflash:
You'll need NVFlash from
here
ZOTAC GTX 1080 Amp! Edition BIOS (to flash to) from
here
ZOTAC GTX 1080 Mini BIOS (to flash back in case you want to revert the changes) from
here
Here's the instructions:
HAVE FUN with the SMALLEST GTX 1080 money can buy... now in all it's silent 0% fan glory! I hope your SSDs, HDDs, or whisper quiet CPU fans are now the loudest thing in your quiet, powerful, luxirious SFF system... time to move up to M.2 to replace those "LOUD HDDs"! >=D
My new super quiet fan curve!
My new card, idling from 25-35c when browsing the web and watching 4K videos, while silent... amazing!:
If you guys would like me to redo some of my old GPU benchmarks to see if my temps go up or if I come across issues, let me know. I'm swamped with work this week, so I'll have to try that out next week when I have some time.
