Hi Community!

I've recently built my first gaming PC my specs are;

CPU - Ryzen 1300x
GPU - NVIDIA GTX 1070 (08G-P4-5170-KR)
RAM - 16GB (Corsair Vengeance)
MoBo - Asus Prime B350 PLUS
CASE - NZXT S340

I can run the Witcher 3 very comfortably on Ultra (In terms of performance/FPS 60+) but the GPU gets very hot (Last test came in at 83c). I actually feel it looks better on my display with settings on High but I'm still getting temps of about 77c-80c after only 15/20mins of gaming.

My cooling - 2x 140mm Corsair AF140 intake fans then Stock NZXT 120mm on the top and back exhausting air. (With this in mind, when I put my hands near the fans I can hardly feel any air movement, even if i set them to High/Turbo and they're definitely the right way round in terms of intake/exhaust). If might be worth mentioning that my MoBo only takes 2 fans so I have installed splitters to run an extra 2.

I would ideally like to shave off about 10c if possible, it would just make me feel more comfortable when playing for long periods. And I'm happy to sacrifice a little bit of the games textures, shadows etc if necessar.

The more experienced among you can probably detect my ignorance, however, any help/advise would be greatly appreciated.

Thank you for your time!

Regards,

Alex

Witcher 3 is pretty demanding and will definitely heat the card up. You card has a blower style cooler which usually runs a bit hitter. The blower style coolers usually run close to 83 or 84c by design so you temperatures are normal. If you want to lower them a bit you can create a custom fan curve using a program like afterburner, you will just have a bit more fan noise.

The temperatures are OK, there's little or no chance of the card being damaged, nor failing prematurely, so don't be too worried.

Sadly, short of changing the cooler ( which you may be able to do without voiding the warranty-EVGA allows this in SOME countries ) there's no real way to drop 10C off the load temperatures without setting a faster-and louder-custom fan profile in the Afterburner software suggested by Krells, and even then you may not get the temperature drop you hope for.

Lazy trick if you're happy at 60FPS: Turn Vsync on, it'll slow the card down somewhat and if you drop some settings a little to further reduce the workload the card will run even cooler.
Why it works:
The card workload is determined by; Resolution, frame rate and scene complexity.
A card producing 60FPS at 1080 rez has to work twice as hard at 1440 for the same frame rate.
A card producing 120 FPS has to work twice as hard as one producing 60FPS.
A card producing a simple frame has to work less than one producing a complex one,
BUT-and here's the kicker-most ignore or forget that rendering 120FPS of simple frames is as hard as rendering 60FPS of complex ones so, to reduce the workload and heat production you need to reduce either the frame rate or complexity or both.

Firstly, i'd like to thank you all for getting back, you've been really helpful! I've recently downloaded the EVGA Precision X software (Think that's what its called from memory!) and its made a slight difference, is the MSI Afterburner better or pretty much the same thing?

Also, for nostalgia I've bought a couple of games I used to play on Xbox 360, one of them being Ghost recon Future Soldier it runs perfectly fine 90% of the time but there are times where it ramps up to 70c-ish and my expectation was that it would run a lot cooler with it being an old game?
