I just built a new PC with these components & Windows 10:
- AMD Ryzen 2700x
- MSI X470 Gaming Plus
- Corsair H100i Pro
- Corsair 400C Compact Mid-Tower
- Corsair 850w 80+ Gold
- Nvidia RTX 2070 Founders
- Asus 24" 144hz Monitor
- Top: 1× 140 mm + 1× 12 0mm intakes with a dust filter
- Front: H100i radiator and its 2× 120 mm discharge fans on the front w/o dust filter. The front case cover is also removed leaving a 3" diameter open hole above the radiator.
- Back: 1× 120 mm intake no dust filter
- Bottom: PSU with dust filter and no shroud
I'm aware the airflow situation isn't ideal, but please read on.
When I first built the PC there was seemingly no issue. I downloaded Path of Exile (a new game for me) and played it at max settings for maybe 1-1.5 hours no problem. I then played Overwatch for several hours with high settings at 144 fps.
Midway through one of my games, the computer locked up and for 30-60 seconds I saw little 50px × 50px discolorations/icons spread around my screen. The computer behaved very haltingly for the rest of its on-time, and when I was finally able to close Overwatch and view other windows I found an error message:
Message: "Your rendering device has been lost! Application closing!"
I immediately opened the door on my case and felt the backplate of the video card which was scalding hot. Did I cause damage to the card?
The PC seems to run fine while viewing videos and writing Stack Exchange posts, but now if I start up Overwatch at minimum settings on 30 fps, the computer will go haywire again after only about 60 seconds. I feel like my cooling can't possibly be wholly responsible for this. Even stranger is that all temperature readouts on my computer say the card never goes over 65 °C.
I've tried uninstalling GeForce Experience and checking to make sure all the fans are blowing the proper direction and even just running the computer with the case-door open.
I've seen several complaints about Nvidia's 20 series having cooling problems so I'm wondering if I should RMA this card or return it and simply get a new one altogether.
Either way I intend to purchase a larger case to solve a clearance issue that stopped me from putting the radiator on top of the case. I fully intend to fill up every fan slot on the new case I purchase and pay close attention to airflow but I'm worried for this card.
What is the core problem behind this error and how should I best go about fixing it?
