Underclocking An Overclocked Gigabyte 2070 S?!

I have an unusual requirement here.
I need a card with a big cooler to sit in a room that is above normal temperatures.

I was looking at a Gigabyte 2070 Super Gaming and the Aorus 2070 Super. Now the Aorus runs hotter than the Gaming so it may seem mad that I am even considering it, but since it has a much bigger cooler and fans I assume that's just because it's overclocked. Obviously I can change the fan curves but the biggest gain should be if I can clock the Aorus at the same clock as the Gaming. Gigabyte software usually offers the option to run the card in several overclock modes so I was thinking if I select one of those modes then it "should" run cooler than the Gaming. Problem is that I don't know for sure. I also don't know whether this is strictly true with Gigabyte cards that selecting a different mode will in fact reduce the temperature. Is it possible for example they are running it at a higher voltage consequently it's impossible to actually reduce the heat as much as I would like? I have no idea how this works. Can anyone shed any light on this? I have never attempted to underclock a graphics card so have no idea, lol.
 
I appreciate that but I don't really want to get involved in manual underclocking. I would have no idea what I am doing. I mean if you are saying that the aorus has been voltage overclocked by gigabyte then its of no interest to me, I guess, and then it would be better to go for the gaming?

Currently running a 2070 WF, coolers ok and is adequate for the job but, it isn't a 'great' cooler, if you want cool running, the Zotac Amp Extreme cooler is huge and ran considerably cooler(1070 version, probably still the same heatsink) and hardly spun up in comparison.

Pretty sure the Aorus coolers literally had bits of the plastic shroud that snapped off in your hand too.:eek:

It tells you HOW to do it but it doesn't fully explain what is going on. I tried it on an old card and it actually raised the idle temp! To me that immediately indicates I don't understand that curve. And it's true, I don't. Why would you flatten a curve horizontally ( GPU Frequency ) rather than vertically ( Voltage ) when you are trying to put an upper limit on the voltage? That just makes no sense to me. You see the thing here is I have no idea how a GPU works, so the process of under-clocking really needs to be "one-click" or I have to take out a week to try to understand what is going on. As far as I know the Gigabyte cards do have single click underclocking ( the various modes ) but I really need to know whether the Aorus will drop in temperature enough if I select say Quiet mode. I can control the fan myself to boost cooling but I need a way to simply turn off any factory overclocking.

Using a different make is largely out of the question because the particular PC has room for a 300mm card, and the Gigabytes are some of the few large cooler designs that fit. The obvious choice would be the MSI 2070 Super but that is a way bit too big.

I think it may be safest to go for the Gaming despite it has the smallest cooler of the three I mentioned. This is simply because it arrives with pretty much no overclock!! I mean I like the idea of the larger cooler on the Aorus but I can not take the chance that there is no way to turn the overclocking off.
 
Can we establish what temperature this above ambient room is? The idle temp was raised when you downlocked - OK, but from what temp to what temp?

Modern nVidia GPU's boost on their own and handle themselves a lot, google GPU boost 3.0. The makers claimed overclockers are largely rubbish, the cards normally boost well above this on there own.

During the hot weather there's been a lot of cases in rooms of 30C+, case temps even higher, 40C+ say, the GPU just looks after it's self.

Also voltage control on these cards is tiny. I'd honestly just pick the one you want and plug it in, it'll be fine.

Obvious choice is to buy a bigger case that will fit a fancy MSI super :p
 
I have no idea how a GPU works but it doesn't stop me from overclocking it, all I know is voltage kills and that's locked. If the clock is too high the GPU driver simply resets and you lower the clocks until no crashes.

**edit doh didn't notice the "underclocking" part.

In theory, but I've had a number of nvidia cards which just aren't stable on boost clocks :/

I prefer AMD's way where the clock speed you set is the clock speed.
 
Is it that you are worried about stability in a hot room? If so don't . My massively overclocked pc has coped far better in this recent heatwave than I have. My pc case was literally uncormfortable to touch it got so warm but my pc just kept on trucking.
Now .. if it is because you don't want the warm room to get any hotter or you want it to run silent rather than fast then that is slightly different. The gigabyte 1080ti gaming comes with 3 settings you can choose but even then the slowest one is not under clocked... It is just not overclocked.... So if you are dead set with undercloking I think you will have to do manually.

You could have course just buy a lower end card. The 6gb 2060 uses far less power which means less heat. It is also much cheaper... It is slower as well of course but if you are under clocking a 2070 so will that be.

Even the super 2060 uses less juice and so will be cooler(infact I would go for that over the 6gb myself)

Well when I say underclock what I really mean is that I don't want the card to be overclocked out of the box. The 2070S is not really overclocked but the Aorus 2070 S is quite substantially overclocked out of the box and that makes a pretty hefty difference to the heat production. The aorus has a HUGE cooler which is great, but I need to switch off that factory overclock. I guess I need the so called "Quiet mode" with a modified fan profile to boost cooling.

The problem is that I have a number of questions about this Quiet mode that no one seems to know the answer to.

Is the mode persistent? It's called quiet mode but does it really mean "not overclocked mode"? Has the 2070 Super Aorus got this mode?
 
Just because it raises the idle temp doesn't mean it is outputting heat. That is the temp on the card and NOT the room.

Serious, look at GPU boost 3.0, the stated boost clocks on these cards mean nothing, there more the bottom limit of what the card will hit. The card handles itself based on temperature and power limits. the stated OC/boost clocks are BS, they boost on their own to max performance and efficiency.

So what you are saying is that all Gigabyte do with the Aorus is provide better cooling, more power, and then adjust the power limits and temperature limits and the GPU does the rest all by itself. So in theory all I have to do is reduce the temperature limit or power limit to undo what they have done. But why is the idle temp with Aorus so high compared to the Gaming. It has a far better cooling solution but there is a very large idle temperature difference.Or is the base core clock specified too? Come to think of it what is the core clock specified say in Afterburner?
( I am just trying to understand how all this works ).

Well reading a bit about this it suggests I don't really need to do anything other than just reduce the core clock to -ve whatever the stipulated overclock is. So in the case of the Aorus it's ( I forget but ) something like 200Mhz? Don't exactly understand why this would reduce the idle temp though.
