Hi all,
I finally decided to update my old setup with a fresh one but I wanted to keep my old GTX970 waiting for the 4000 serie to come out.
The build went well and Windows was running smoothly when I decided to try and launch a game. As soon as the GPU got load, its fans went immediately to 100%. After a parallel analysis with HWiNFO, it seems that the GPU temperature rises instantly to 85-90°C as soon as it's under load, which triggers the thermal performance limit. The thing I can't understand is why the exact same GPU never goes over 75°C on the old setup, having the fans around 45°C. The result of this is actually worst performances (same game, same configs, same monitor) with the new system due to the thermal limiter.
I kind of doubt the exactitude of this GPU temperature reading, even thought it's similar on both systems at idle (~40-45°C with a room temp around 22°C). After a couple minutes under load, the heatsink of the old system is really hot (could be around 70°C, but I don't have an IR thermometer) whereas the heatsink on the new system is barely hot. This actually matches the GPU VRM temperature readings, which are around 70-80°C on the old system and 50°C on the new one.
Would you guys have any suggestion where to start looking ?
