Hi guys, I am testing a used video card, the seller says it has had little use but I'm not sure, the people lies all time.
1. Furmark with default ventilation (without control softwares) when the card reaches 76º, after a few seconds, the video signal stops and I must to restar my PC to obtain video again.
2. Furmark with controlled ventilation with msi afterburner, the card reaches maximum 67º-68º (fan speed 100%) for 10 minutes without problems.
3. Playing red dead redemption 2 with ultra-high graphics for considerable time and with controlled ventilation with afterburner, 66º approx and the card is fine.
As I can see, this card stops working at 76º or 77º and I would like to know if this is normal or this card is bad or has been mistreated. I am confused because there are people who say that they can get temperatures of 80º and 90º and it seems that their cards work without stopping.
Obviously I always try to maintain a temperature below 70º using the ventilation control but I am concerned to know that this card always stops working at 76º.
Coincidentally when I check the bios in GPU-Z, I can find a value called "Temperature Target 77°" What does this mean? Is this a safety limit? An automatic shutdown or something?
Thanks I hope your help.
