90 c on GPU while gaming

[Kodas]

I have 2 980 ti SLI, I have 2 1080p monitors hooked upto my seconds card, one of them is 60 hz connected through HDMI 60hz, other is Dual Link DVI 144hz. When I game my 2nd GPU goes up to the low 90's (in Celsius) the other one is at 80 or 70 C. While im not gaming the 2nd one is stays low 50's C, the other GPU is at low 60's. Are those temps safe? If not what can I do to make them less hot while game or just less hot in general. Sorry if this is bad I dont speak good English. Thanks

Oh and forgot, I have not overclocked yet, im scared to do so.

The maximum safe temperature for a 980Ti is 92 degrees. So if you stay below that, you'll pretty much be safe. But if you're hitting that and remaining around that region for hours, I'd say you'd want to enhance your cooling capabilities. But if you are generally staying below the 85-90 degree mark, you'll probably be safe. Just I wouldn't stay too high for hours on end.

- Ensure the ambient temperature of your room is minimal, a hot room means hot air being drawn into your case
- Ensure there is adequate air flow in your case, cool air entering at the bottom, and exhausting out at the top. (Look at positive / negative air flow)
- Give the PC case and components a good clean regularly to remove dust and grime build up, also ensure cables are properly managed, bad cabling damages air flow
- Maybe including side panel fans to rapidly extract hot air from the CPU / GPU can be useful
- Bigger cases typically have improved air flow when configured correctly
- Reapplying GPU thermal paste has helped in some circumstances
- Bear in mind your top GPU will likely always run hotter as it is probably drawing hot air from the GPU below it, so side panel fans can help extract this hot air.

That is because hot air is accumulating in the case most likely. Try removing the side panel for now as it will improve temps (as a temporary solution before you add more fans to the case).

What they all said.

What you can do as a test is see if it is an case airflow problem. Take the side off the case, aim a small house fan at it while gaming. If the temps go down to normal ranges (80c I believe is the average temp limit most AIB partners set for) with the fan aimed at the case, it's an airflow problem. If the temps stay high, you might have a card problem.

A case airflow problem means you either need a bigger case (twin 980s generate 500w of heat, plus your CPU!) or more powerful airflow. This means you could (assuming you already have a larger case) - add fans. You want to look at your fan mounting points and figure out an airflow pattern where air comes in with fans pointed in at a low-frontal position, and then exhausts out the back/top with fans pointed outward. This moves air efficiently (hopefully). Another thing you can do (if you can) is remove HDD mounting brackets that you don't need. These can impede airflow. If you don't need them, why have them?

If it's not the case airflow, check and make sure your fans and heatsinks on your GPUs are clean! Dust buildup not only impedes airflow across the heatsinks, it also actively traps heat (insulator). Use canned air or a small air compressor blower.
