During the evaluation process of the RTX 5090D graphics card, reviewers encountered an anomaly: the Hot Spot temperature displayed on the GPU-Z sensor panel consistently read 255℃, which is highly unusual. Initially, it was speculated that this was due to GPU-Z software not being fully compatible with the new graphics card. However, Wizzard, the developer of GPU-Z, recently revealed that NVIDIA has opted to remove the Hot Spot sensor from the Blackwell RTX 50 series of graphics cards. Consequently, future iterations of GPU-Z and other reputable hardware monitoring tools, such as HWiNFO, will cease displaying the Hot Spot temperature for RTX 50 series graphics cards, focusing solely on GPU and memory temperatures. Typically, the Hot Spot temperature signifies the hottest point on the GPU chip, often exceeding the GPU temperature by over 10℃. Given that the RTX 5090D boasts a power consumption of up to 575W, the specific rationale behind this removal remains unclear.
