See this screenshot, vBIOS can have only 3 points for fan curve, this is what I edited in this vBIOS. Next to it a presentation of this curve using MSI AB fan settings.
Thanks for the feedback for the fan parameters!

my case is the corsair vengeance c70 with 3x 120 intake front and bottom + 3x exhaust 120mm 2 from the rad of the h100i at the top + 1 in the rear of the case.
I see most of the users hovering around 65-70c on air mine went up to 80c in few occasions.
for the thermal paste I used noctua NT-H1
also have some CLU liquid metal somewhere but didnt try it yet.
I would NOT recommend using CLU/CLA *EVER* on a GPU. It's electrically conductive... now look at a GM200 GPU and see what is all around the sides?
There is also no guarantee re-applying TIM is going to make a huge
difference but I bet it did (just how noticeable). It's very difficult to do an equal comparison if things like ambient temps are even slightly different. Your TIM may also need curing time (but NT-H1 has a very fast curing time) so maybe it will get better in a day or so?
Having said that, as far as temps that others report, people don't like to report worst case scenarios
I can run a single firestrike test without the demo and then again with the demo
and have drastically different temps at the end of the run
. That's just one example. Anyone that has a GM200 chip and it's being cooled by AIR can't avoid temps approaching 80C+ if the conditions are right (4k resolution, max settings, next gen app/bench, prolonged periods of use). I was getting 80C all the time when on AIR and pushing my GPUs hard.. this wasn't
abnormal at all... I have VERY good cooling in my case, supplemental fans dedicated for my GPUs, a custom fan curve and my case side open when I recorded these temps below.
Since I have SLI, the TOP GPU does get a bit hotter (these are from the top card) so single GPUs folks out there will see temps a bit lower.
See this chart (right-click open in a new tab for hi-res)This is exactly why water cooling GM200 is really where it is at.
You will most likely be thermal limited (INCLUDING your VRMs
) long before you are GPU limited. "BIG Maxwell" is just a huge die and due to pure physical size it just screams for a water block.
As long as you don't go over 85C you're fine (MAX is 91C but don't let it get over 85C) you won't melt anything HOWEVER you should
look to improve cooling as much as you can..
Use a ghetto fan
or find other ways to improve airflow and cooling.
Seriously... do that ^Got Ghetto?

This is an interesting one and not very common. What it appears to be happening is that your power supply is unable to maintain reliable power delivery to the GPU. As soon as the power consumption increased to 103.3% the voltage delivery fluctuated probably because of the power supply momentarily couldn't handle what was being asked of it. Your boost clock immediately dropped (self-protection mechanism) where you can also see the power consumption dropped accordingly. Once the power draw was back in range of what the power supply could reliably provide everything stabilized again and your boost went back up.
Also, make sure you are not using any adapters/splitters on your PCI-e cables. You need direct/straight runs to the PSU.
The good news is that you may be able to use a workaround... overclocking your MEMORY actually increases the power draw. Put your memory back to stock, you might be able to get by like that.

Cool! Thanks keep us posted.

It will boost to 1455Mhz, hit 66c then throttles to 1442 or lower. Would the increased P00 and P02 values in the voltage table stop this happening? I am basically trying to get the card to run flat out until it hits 75c+ as I do not believe 65c should cause the card to throttle.
Setting 1300mV and Kboost it reaches higher temperatures quicker, power limit can go upto 118% but again, around 66c the card throttles down and even drops to 1190Mhz if it gets to ~73c
A couple of other things, this BIOS shows 'Boost Limit 1455.5Mhz' whereas mine is greyed out - Will this be the top limit?
The version of this one is 84.00.36.00.92 and my current one is - 84.00.41.00.90 - any issue?
Hi there.. These tweaks should work on a classy just as well as on a Gigabyte...the only question I have is about voltages because EVGA's cards are usually voltage limited until you use some special software that will address the voltage controller? Is that correct? We've got someone testing a classy BIOS right now but he's been busy.
You are welcome to give this a try yourself
. Just extract your current BIOS and compare to make sure this is compatible (not sure if EVGA has different revisions of the classy).
