My games run really well.. for 5 minutes. Need help!

[insomniac333]

Hello guys, i have a bit of a problem here. Games like MGS5, Mad Max, Witcher 3 run very smoothly on my PC with constant max fps with everything maxed out. Problem is though that whenever i play a game for around 5 min or less my screen freezes for about 1 second or less and then everything turns to crap and my fps drops to around 30-35 or so. I have tried cleaning the inside of my PC with a compessed air can but nothing has worked as of yet.

Specs: GTX 780 i7 haswell windows 10 64bit 8gb ram

These are my temps in order: http://imgur.com/a/D8qqe First pic is when i just got into the game, Second pic i just had stood still for 4 min. Third pic i went into the car and spawned outside the area. Fourth pic is when the mini freeze and fps drop had occured. May i add that i was a second or so late when i pressed the screenshot button on the last picture, but my GPU was around 80-82C when it froze.

Any help would be appriciated! Thanks!

80-82º Celsius? That's rather high. You need better cooling. Either more fans or a better case with more fans. That's as far as my knowledge will take you. If there is a liquid cooler for your GPU, get one.

Use vsync or use rivatuner to limit your FPS to something lower than your max fps.
Is your game on an SSD? The problem could also be that the game has to read something (like textures,try to lower texture quality) but can't do it fast enough.

Nope, i do not use an SSD also using vsync doesn't seem to help. I've tried limiting my fps to 60 but that doesn't work either. If i limit my fps to 60 it will drop to 20-25 fps instead of 40-30. I have nearly an identical rig to my brother the only huge difference being him using 16GB RAM and me using 8GB RAM. Maybe it's a RAM issue then? I'm not sure.

I have contacted nvidia and they have told me that 80-82º isn't optimal but shouldn't be that big of an issue. I will try to get a better cooler though! Thanks

It is cooler on graphic card most definitely. It works smoothly until it gets over heated.
