Hello, I am just wondering if I should worry or not about my card. It's not the latest or greatest, had it for two and a half years, never overclocked it.
"Newer" type games, temp is getting to around 80 - 81C.
Yes my PC is in need of a cleaning, unfortunately like a dumbass I've been known to smoke cigs in the same room around it, which I've since stopped.
I've noticed limiting the FPS lowers the power, and in turn the temp but I don't want to limit myself too much.
Is there anything else I can do to lower the temps other than the obvious cleaning of my PC, since I can't afford a new card currently.
It's the MSI RTX 2070 single fan blower model. Should I even worry at all? Of course the card throttles if it gets to 82.
I have a custom fan curve in Afterburner to up the fan speed, but honestly that doesn't seem to do much.
Thanks in advance

You don't have too much freedom with a blower card. To get 'adequate' cooling from that single radial fan when playing games, you practically have to run it at max - or darn near it.
If you don't, the strength of the airflow being pushed towards the rear exit starts to fizzle down and thus it takes longer for the heat to be removed from the gpu.
The quirks with blower gpus are different from the much more common axial fan cooled ones. The biggest con with them is probably how audible they can get because how necessary it is to run the fan high.
On the plus side, they don't dump their waste heat in the PC, and excel in tight spaces.


To aid in reducing power consumption:
A)cap fps to monitor refresh rate
B)experiment with a 90-95% power limit
C)undervolt, which is like B, but with more steps.

Yeah I don't even understand the point of the single fan. But, should I be worried? Other than running loud what do you think, crank the fan speed to 100 when GPU reaches 60C
When I have $$$ again I think on my new card/PC I'm going to go with GPU cooling system
Can I configure 90 percent power in Afterburner -Edit stupid question I can, but when I do it reduces the max temp automatically.
What kinds of effects will limiting the power have on performance.

The point, or where the blower cooler excels, is multi-gpu setups, or SFF setups where the gpu is smashed up against a psu shroud or limited breathing room.
Worried? No. Gpu Boost is taking care of things. That's why it's dialing back on its own and keeping thermals ok.
60? Well, if you want... but I'd think more like 70-78C.

Unlink power and temperature limit by clicking on that chain link icon next to them, then you can move the sliders separately.
It should tell the gpu to cut back on it's power draw with minimal performance loss. Capping fps does more of the same thing, so you could combine A and B or A and C, if desired.

Thanks all for the comments. As long as I don't have to worry about my card running that hot I should be good.
In any case will experiment with capping FPS and decreasing power limit.
How's the GPU market currently, is it still nigh impossible to get a 3070 or 3080

Likely depends on your country, but it seems that right now, it's a lot easier to grab one and at much better prices basically everywhere.

Before limiting power and reducing performance immediately, I would fiest look into undervolting. You can, for example, see what frequency your card runs at normally, then use the curve optimization tool in Afterburner which would result in a OC curve, and then clip the curve slightly above the desired frequency. That should result in a stable baseline undervolt you can either leave as is if temps are fine for you, or improve further. And it's the easiest, beginner-friendliest way I have found so far. For example, my current 3070Ti runs at a stable 2010MHz OC with an undervolt to 0.970V. It's not super optimized, but I have never seen my card reach power limit again and temps don't even come close to 80°C despite higher clock.

I'm going to have to check out some guides as over/under clocking of any sort is new to me.
Apart from the good olde "turbo" button on 286 and 386 machines back in the 80s and 90s lol
In the meantime, it can get cold in my room and my PC is currently acting as a space heater

You can, and probably should, combine both capping fps to monitor refresh and undervolting for the greatest effect.
With regards to undervolting, you first need to find out what the max core clock and voltage your gpu will ramp up to. Once you know those 2, go into Msi Afterburner and open the Curve Editor.
Take the max voltage that you monitored your gpu hitting, and subtract 0.05v from it. [Ex: 1.031 - 0.05 = 0.981]
With the new value, find it on the voltage/frequency curve, click on that point and raise the frequency to the max you saw, but add 10.
Lock it in with the L key and click apply. Save the profile in one of Afterburner's save slots and then click reset - don't need to have it running at max while you're not doing anything.

If the gpu crashes, dial back the voltage offset to 0.04v, 0.03, etc, until stable.

Yeah, the downside of this is that you will have to run Afterburner every time you want to play.

I keep it running all the time pretty much anyway.
How would I determine max clock and voltage?
EDIT - duh I have an extensive history here in afterburner because of using it all the time.
My core clock max was 1890, My power (in watts) max was 176.8
I don't see a graph for volts but still looking
Voltage max 1 volt? Does that sound right?

Go into Afterburner settings > Monitoring tab. Scroll down until you find Gpu voltage, check it, and click Apply.
It should then appear in the monitoring graphs.

Sorry I edited my post a bit while I was looking thru the graphs.
They are all pretty much checked, I found it in my history since I haven't restarted my PC in a few days at least.
1 volt was the max. Good bit of data too as my max GPU usage was 99. Voltage limit is the only option to display, there is no GPU voltage.
Do I also need to unlock voltage monitoring in the general settings?
But then like an idiot I accidently quit out of Afterburner so I'm back to 20 minutes of data lol

Or you could simply use the curve editor... I did it kinda the other way round, I let the curve editor OC my card, then capped the curve at the target voltage +15MHz and stress tested for stability. Resulted in an overclock, even. And so far, it ran stable under all situations while showing normal behavior.
