Motherboard reaching temps of 80c before game crashes, constant stuttering and pop in.

[Maxtastical]

CPU - AMD FX-6300
GPU - AMD Radeon R9 380
MOBO - MSI 970A
COOLING - Corsair Hydro Series H60
RAM -16GB

My CPU and GPU temps are perfectly fine but in HWMonitor, TMPIN1 (which from what I've been able to find, is a heatsink on the mobo) slowly climbs until it hits 80c before it crashes. My first 2 days with the game were fine. Other that some stuttering and pop in, it played pretty decent. Now the stuttering is nonstop, pop in is aweful (things are popping in 3 feet in front of me) and my mobo is getting seriously hot. I've played a few other graphically intensive games since this happened and they are not having the same effect on my pc at all. I notice when I'm standing still in the game, the temp slowly drops and as I'm walking around and terrain is loading, the temps start climbing up until it crashes.

I know there isn't anything that can be done about it and it's most likely casued by the fact that the game is poorly optimized at the moment. I just wanted to see if anyone was having similar results and to put it out there that you should be checking your temps while you're playing. I have 3 case fans, liquid cooling with fresh thermal paste and for good measure, I even have a powerful Honeywell fan pointed at my rig.

I love the game, been having a blast playing. But I'm not willing to take the chance of having my PC damaged, it's just not worth it. I'm going to send this information to the devs and if there isn't any way to fix this issue, I may try for a refund.

Put a small fan on the heat sink on the board and direct the air away from the heat sink, that should cool it down to the point where you can run without failure. I have a 990FX board with massive heat sinks and 6 case fans and I havent had any problems. But some of the 970 boards do suffer from overheating.

Thanks for the response but I don't feel like I should have to make modifications to my pc just to accommodate one game.

games are made to stress the hardware think of it like hotrodding you got to balance out the added hardware with strengths and flowing the engine.
msi afterburner should be one of the first things you get not to tweak clocks or high tech stuff but, to set you fan profile on your GPU (video card) so you dont cook it when you are pulling next to a maximun load. dont just add a case fan, add it so it draws heat out of the box the most efficient way possible.
remember using ribbon cables back in the day?
computer tweakers twisted them to lower the airflow resistance in the case to maximize the airflow and heat extraction from the case.
now we have the sata bus and round cabling from the get go.
thats the community driving computer design.

As Dave mentioned above it does appear that the 970 is prone to overheating, but can be managed with well designed airflow. You likely don't notice this issue in other games because they are likely optimised enough, or aren't as CPU intensive.

Firstly, take away the Honeywell, and put the side of your case back on. You simply will not have effective airflow with it off, and your case fans become largely useless.

You have 3 case fans. What configuration / locations?

You have hydro cooling on your CPU? You need to improve your case airflow to compensate for the lost airflow that would have normally been flowing over your MB from the CPU fan -- especially for one that is known to have overheating issues.

Have you set a custom airflow curve for your GPU, or still running standard?

When running Subnautica what is the utilisation rate of your CPU and GFX Card? Especially versus other games that you don't have issues on.

And lastly, what is your current ambient temperature?

If you don't want to make any changes to your rig, then that is perfectly fine, as the eventual cause may simply be the heavy CPU use of the game at the moment overtaxxing your current chip. Or with some simple changes your issue could be resolved.

Answer the above if you want to try and work through it, or just leave Subnautica sitting on its Early Access heels until they get around to optimising it prior to release :)

This is entirely hardware related - you need more cooling for your PC. You're simply getting it in this game and not others because this game is the most intensive.

Even when/if they optimise the game, you're going to have this problem again whenever you push your PC to this point, and games are only going to get more intensive as time goes by. Fans are really cheap, so buy some more and either install them yourself or get some help for it.

Subnautica has had problems with the R9 series ever since the H2.0 update.

Try running in D3d9 mode - find more info on this in the PINNED thread titled "TROUBLESHOOTING: READ THIS FIRST!".

You can run Prime95 on your machine for 5 mins, and take a look at the temperatures. If it reaches close to what Subnautica does, then it's your hardware, or lack of decent cooling of your hardware that's an issue. Most games do not push CPUs far especially single-threaded. Subnautica does, but within a PCs supposed means.

To me this sounds like a simple and cheap to solve cooling problem. The cooling is obviously insufficient. If you are unwilling to improve that you cant run any game that makes your rig work hard. The lack of cooling makes it impossible for your rig to deliever the performance it could deliver.

The load games put on a pc differ a lot, even if it looks the graphis are of the same quality. For example on my rig Sims 3 pushes the temperatures way more up than Battlefield 4. 7 Days to die keeps my cpu load at around 25-30%, Battlefield 4 manages 80+% with corresponding temperatures. However, just by cranking up the case fans the temps drop quickly.

Compared with the cost for a gaming rig fans are cheap an will solve your problem. Games will become more demanding as they do since ever, your problem will grow and restrict what you get out of your investment more.

I'm just curious what fan setup he has. Considering he is using a hydro cooler for his CPU, he is missing out on the natural cooling effect that would pass over the board from a direct fan-based cooler. There is nothing wrong with a hydro cooler, just simply need to accomodate.

In addition he states he has 3 case fans. I've got to wonder if he is counting the hydro coolers radiator (with fan) as one of them and that I sincerely hope the radiator is fitted with a good static pressure fan connected in a push configuration.

Lastly, the simple act of checking the flow of your case fans, and maybe even flipping one, could have a drastic improvement. Firstly, and personally, you'd want to run positive pressure. A good way to know if you are is by checking the airflow direction on any of the case vents not connected to a fan. If air is flowing out at a reasonable rate, you're good to go. If not, flip a fan around.

Obviously you'd need to put the side of your computer back on first to test...

I once discovered that by changing the direction of just one of my case fans near the CPU, and by removing the case fan filters (meh) I was actually able to substantially increase airflow and achieve stable temperatures 10 degrees lower than registered previously. Took me but a moment, didn't cost a cent, and had great results.

Sims 3 needs v.sync to keep those high temps down. Also the use of mods like "relativity" ( http://nraas.wikispaces.com/Relativity+FAQ )keep the townie scripts from overtaxing the CPU, you set the interval to 13 so it runs at 0.35 normal time, hence it gives you more time in the day to fulfill your needs and skill up, while life for the townies goes on like normal. NEWAYS... :P

About airflow.. My case is a CM HAF-X airflow is like this:

I'm not sure why people are telling me to put the side of my case back on, I never said it wasn't. I have an intake in the front and bottom of the case and the radiator for the cooler is blowing out the back and another out the top. The ambient temperature inside my case is about 38c, my GPU never goes over 60c and my cpu tops out at around 38c. Everyone seems to think this problem is cause by me not properly knowing how to manage the airflow and temps of my pc and that is just not true.

I'll trying running the game in d3d9 mode as suggested by Cougarific but any type of modification to my hardware is not going to happen, everything else I've played on this machine works perfectly fine. I see a lot of people complaining about their games crashing more and more frquently as they play and I'm thinking they are having similar problems as me but aren't checking their temps in HWmonitor as I am and don't know that the game is crashing due to high temps. I could be wrong but this problem has nothing to do with my setup.

and you know this unequivocally?

[Jammy]

i'll have to add, the HW monitor isn't always accurate....it tells me on occasion my cpu is running at 14c, even though the ambiant temperature in my room is 20c-ish
