1080ti to fan curve or not?

[DaGabaGhoul]

I have a variation kind of custom 1080ti FE. Obviously the fe is a blower style and I read they tend to operate hot. Now I have seen people say that these cards a pretty much designed to operate hot but then I see other people saying pascal works best at lower temps. So lets get to the point, I recently started playing PUBG at 1080p 144hz. First game to really challenge my gpu at 1080p. I hit 144 with no problem and play with no problem with everything at ultra. Now my temps go to 84c and just stay there. No throttling at all if there is it is so minimal it can not be detected and no problems at that temp. I still thought it was high and after reading I decided to set up a fan curve. The fan curve is a bit more aggressive and brought my temps down to around 74c. So about a 10c change, this is where it is interesting. At 84c the gpu stabalizes with only 48 percent of the fan being used. on my custom fan curve when it maxed at 74c my usage was all the way up to 75 percent! So im wondering is using that much more fan power really worth only 10c cool down? should I try a more aggressive curve or is it even worth it? I see people post all the time 84c is fine but of course there are others that say no fan curve it. ty for any insight on this issue.

Simple question: do you consider the 75% to be noisy or not?
Of course lower temps are always better.

Something to try would be to set a global FPS cap of 150, I only have a 60Hz monitor with a 980 Ti and have a global cap of 70, since doing this my GPU temps have never gone above 60c.

Technically your card is slowing down at 84c, the maximum boost clocks are achieved below 50c with it dropping as temps increase, now it won't make much difference in reality, so it comes down to noise, run the fan as fast as you can until the noise annoys you, cooler cards are always better and in Pascal's case will run faster, it will have more of an impact if you overclock, at stock on a blower card at 84c I'll guess your boost clock is around 1800-1900MHz with being watercooled and overclocked my 1080ti's run at 2076MHz bringing near 10% extra performance.
The hottest a card gets, the harder it is to maintain a high clock.
If this matters to you is another thing entirely.

the game caps at your refresh rate. so for me 144.
also that is why I get high temps. If i play on 60fps with the stock curve it doesnt even get to 60c.

if it is slowing down at 84c then the hw monitor readings arent being affected. it maxes out at like 1800 something whether its at 84c or 74c and its doesnt go any lower when it hits that temp. I truely do not know why its doesnt hit over 2000 I really do think it is the version of my card. either way though untill I look into a water cooling solution for a gpu. I really like your input monk you actually have the card I cant stand when someone trys to tell me what my card is doing when they dont even have it. So I appriciate your advice on the matter. I think my card would slowdown when it hits 85c since the thermal max i have it at is 84 I think.

now as far as noise. It really doesnt bother me too much I am a headphones type of gamer. it does get way louder than the stock fan curve because the stock fan curve wont even go higher than like 50 percent speed even at 84c. So since I dont mind noise im really more just asking whats worse for the card, fan run way faster/more powerful or the card running in the 80s? like which is perfered. Online I see so many people with 1080tis saying they just leave it running in the 80s idk if its just me but I get a little werid about that. So yea is it just me or should i leave the custom fan curve on to keep it below 84c even if it is just about a 10c difference. I tried setting it to go a little higher a little sooner and see if that helps but idk. So yeah any ways sorry for the long winded poorley spelled question. higher temps vs higher speeds? and is it even worth it?

Games do not "cap at your refresh rate", some games have a 30/60/120 fixed cap, some do not. One example is a game I played just before placing a cap, Rescue Team 7 and without the cap I was getting over 200fps and it was stressing the hell out of my GPU, hence why I set the cap up.

Thing is at 74c you have already gone past multiple steps which slow the card down, in my testing there are distinct drops around 50c, 63c 70c and a final one in the low 80's.
These drops will vary a bit from card to card, and being overclocked will show the changes more clearly than stock.

I've had alot of 1080ti's due to alot if bad cards, the fastest card I had would hit - easily with no need to mess with voltage curves etc - a huge 2150MHz it was a true silicon lotto won, sadly, it had faulty memory so had to be RMA'd :(

wowww thank you for that explanation. when most people talk about thermal throttling its always in the higher high temps. people will say 84 is fine as long as it isnt throttling, but no on really explains that it is always kind of throttling. thank god then i got a two year warenty on the card and certain other parts in the system.

ok with this info Ill continue using my custom fan curve untill I hear anything different about if i should or not. Ill def tweak the curve settings here and there and see what I can do. I really do know if i like blower cards all that much but i didnt really have a choice. Will look into water cooling posibly in the future for the gpu. I appriciate the info on thermals for real!

sorry about the card failing on ya but god those speeds sound amazing!!!

pubg caps to your refresh rate. games that i play in vsync cap to my refresh rate. The game i was talking about in my post is pubg. Feel free to look up what I am saying if you do not believe me but pubg caps to your refresh rate which mine is 144 it doesnt go any higher. using an fps monitor i see that it is complteley capped at 144. Also I said the game not games in general. So yeah either you didnt read it or you assumed I was speaking about all games.

Of course lower temps are always better.

sorry i did not see your post. It isnt to noisy I think but it really seems to really power up around 70 percent didnt even know it had that kind of power sounds like a frigging jet turbine lol.

Maybe throttling isn't the best word for it, but the cards do all step down as they heat up, well pascal anyway.

I have had 7 1080ti ftw3 elite editions and I fear it was the upgrade from ftw3 to the elites painted metal shroud that caused most of the issues with assembly not done properly.
On a plus it gave me a good insight into the variance of the silicon.
Best hit 2150, worst wouldn't maintain stock non boost speeds dropping into the 1500's, most cards hit around 2025-2050 with mild tinkering before temps caused them to drop, only my final pair have been under water.

wow lol. I know exactly what you mean its crazy how something as small as the lidding process of a processor or a paint on a shroud can mess with temps. now the ftw they are not blower style they are that regular style (cant remeber the name takes air in blows intocase etc.) either way I have heard blower styles like my 1080ti run a bit hotter then the style of cooling on my msi 1060 6gb or your ftw. not only that I am not sure how much I like that a blower style needs to stay on all the time. So much more dust running through it compared to the other style of cooling where the fans stay off until they are needed.
Im not sure what the stock boosts on the FE but idk can they reach over 2000? I saw most people saying there FE was under that but im not sure. I know I havent hit 2k yet and i dont expect to with this cooling lol. But with the new curve I think I am able to hit bit higher I cant remeber if it was high 1800s or low 1900s. Will def do more testing.
I wonder if it was the paint on the elites that were causing you a problem?

Also after some testing and research. Any throttling I am getting doesn't seem to be from temp yet majorly but actually voltage. I may be wrong and I want to see. Also I read something about the ftw breaking something to do with vrm. I am sorry about that they look like fast cards.
