The temperature of the core is pulled from MSI Afterburner with the max reading used after a completed run of 3DMark Vantage at the Performance preset.
Looking above, you can see that the MSI R9 290X 4GB Lightning OC runs very warm when just sitting idle. With these high idle numbers, I found myself worried that when it came to load we would see the card shoot into the 90s.
Looking above, though, you can see the variant is very small and we're looking surprisingly strong with a 72C load temperature. Considering the overclock and the fact that the R9 290 cards are well known for running extremely hot, these are some very impressive numbers.
