My RTX 2080 ti is getting super hot when I play games like Runescape, hitting temperatures around 82 celsius. I recently bought a new pc case you can see in the link below, but I had to make do because of money issues. I was planning on using water cooling with my Thermaltake tower 900, but since it was cheaper than buying a whole new system, I ended up getting a different case that supports air cooling instead. Now I'm using an Lian Li Lancool case and have managed to keep the temps down to about 70 celsius. This is still too much for me though. I would like to know if I can underclock my GPU so it doesn't get hotter than 60 to 65 celsius? I've installed Afterburner, but I don't really understand how much I need to adjust and if it's safe just to slide everything all the way down. CPU: Intel Core i9-9900K at 3.6 GHz with 8 cores. I got my CPU cooler from Thermaltake for $199.99 on Amazon, called Floe Ring RGB 360 TT Premium Edition with a fan speed of 42.34 CFM. My motherboard is an Asus ROG MAXIMUS XI HERO ATX LGA1151 at $469.00 from Best Buy. I also have memory from Corsair, which is Vengeance LPX in 16 GB total (two 8 GB sticks) running at DDR4-3000 with low latency of CL16 for $71.98 on Amazon. My storage is a Samsung 970 Evo 1 TB M.2 SSD from B&H that costs $179.99. My video card is an Asus GeForce RTX 2080 Ti in the ROG Strix Gaming OC model at $1279.99 on Best Buy, which has 11 GB of VRAM. I'm using a power supply from Corsair RMx rated for 850 watts with 80 plus gold certification and full modularity to replace my old Thermaltake tower that was already installed.

That is not strange for this kind of power GPU card. I would only worry if it was from the 90s. Lots of people say their cards get old too, like the 80s. You have a CPU that also makes lots of heat. Just make sure your case fans are in the right places to move air around and keep things clean with no dust.

Why are you scared of 70 degrees? That is way too hot for that card.

1. take a look at this: How to lower the speed of your graphics card for better performance Learning about underclocking your GPU is quick and easy. Changing how fast your AMD or Nvidia card works might seem strange, but check out www.wepc.com 2. use a software fan curve program with Afterburner (like turning it down when the heat gets high).

I don't need to stress. Your graphics card gets hot because it has to work hard, but that's normal. It likes to stay cool just enough to keep running smoothly at a good temperature. Eighty degrees Celsius is the usual target.

It's a waste of time buying a 2080Ti and messing with underclocking your graphics card since there is no real benefit.

The heat inside the room is really uncomfortable. The glass in front of me on my case feels super hot, like it's a radiator. Also, games such as Runescape don't need that much heat, right? It's not just about the game I play. I wanted to set up water cooling but ran out of money. So now I am asking myself two things: can I take off the GPU cooling fan and how do I do this using Afterburner?

Why didn't you look at the link about the afterburner that I sent back then?

The best screen to see is this one. Click on Options [like a gear], then go to the last tab at the top [User Interface]. Skins are at the bottom. I am using MSI Cyborg Afterburner skin by Drerex Design & Skin composition mode = traditional. After doing that, just slide the Core Clock slider to the left to undervolt my 2080 Ti. By the way, my GPU is an MSI RTX 2080 Gaming X Trio, which will have different base stats. https://imgur.com/rsHNp9a
