@ Myffas - I test all my GPUs with this Baking temp for 2 days. This doesn't mean I recommend running GPUs at that temp, it just means if there's any failure, it will show up faster with higher heat temp. MSI Armor 480 run very hot. They're not as efficient as the MSI red. Even then it depends on the RAM and ASIC, etc. If you have 7 GPU in a rig, it wouldn't be surprising to see 1 run 10 C hotter than the next even if it's on an open air rig on the outside vs middle. I recommend trying to maintain Ambient temp 95F or less for longer GPU life if possible. As long as the intake air is in that range or lower, you're fine. 390s handle heat the best but they also run stupid hot and then it's 480. The 470 are very stable but do get flakey once ambient temp is 100F or higher if you're not using box fans. Armor 480s are my least favorite although the Armor 470 are very stable. Both run hotter than the RED version.
Yun, thanks for your insight about card’s ability to handle heat. How would you rank the references cards sapphires 480 and 470 compared to the other ones?
These blower versions were great for my whole house GPU heating system. Your thread made me think about sharing my experience of home heating. I've been able to maintain my house at a stable 24°C when outside temp was close to -30°C. I'll take the time to share a few pictures when I'll finish this expansion.
Just to complete my fan design, does is happen that your hot side gets higher than 115F when your intake is at 95F? It seems that two choices may make sense: cheap GPU cooling (armor's) with expansive industrial fans or good cooling on GPU (Red's) with medium capacity exhaust fans. The decision all ends up into each cards maximum exhaust temperature, while supply is at 95F. I may be a bit too technical about this, but I agree with you, over engineering can cost a fortune.
