I recently purchased a Gigabyte RX 7600 8GB OC edition about two weeks ago and decided to run a stress test using 3DMark Time Spy. During the test, I noticed that the hotspot delta reached 40°C, though while gaming, it stays around 30°C maximum. I've come across conflicting advice online; some folks say a delta of 40°C is within normal limits, while others believe 30°C is acceptable, and a few even suggest it shouldn't exceed 20°C. I also shared this in another forum and got mixed responses. I'm wondering if I should be concerned or consider an RMA. Here's an image of the readings I got: [imgur link for image](https://imgur.com/a/5T0YeIh)

That delta is generally fine! As long as your hotspot temperature remains under 100°C, you shouldn’t worry too much. The critical factor is whether you're reaching extreme temps during use, which it sounds like you’re not. So enjoy your new GPU without stress!
The maximum junction temperature for AMD GPUs is actually around 110°C, which is when they begin to throttle. So in a sense, you are safe until you’re close to those figures. The delta between average and hotspot temps can usually range from 20-40°C, which is pretty much standard across many GPU brands, even if they don’t always show that data prominently. However, I can see why it might be concerning when you're able to monitor those temps directly!
Honestly, I’d consider returning it. A delta that high on a new GPU might suggest something’s not right, so if it’s troubling you, it’s worth getting peace of mind through an RMA.
I can see your concern, but typically, a delta of 30°C is common while gaming. If yours is at 40°C under stress, it’s towards the higher end but still within a safe zone, especially if you aren't hitting the mid-90s range on temperatures. You might want to check your fan curves if things start rising beyond that, but it seems manageable right now. Just my two cents!
The most demanding game I run is The Finals, where my GPU usually stays at around 50-55°C, and the hotspot doesn’t exceed 80°C. My fan curves are pretty responsive, starting at 40% until 70°C and ramping up more above that. Here’s how I set it up: [fan curve image](https://imgur.com/a/nympp03)
Do you have any solid sources that back up the 20-40°C delta norm? I’ve only seen anecdotes and varying reports, not anything very concrete.
