Don't worry, 110°C is "expected and within spec" for AMD's RX 5700 series

AMD's 'hotspot' temperatures live up to the name.

Don't worry, 110°C is "expected and within spec" for AMD's RX 5700 series

Early users of AMD's RX 5700 series graphics cards have been worried, seeing high temperatures for their GPUs while seeing AMD cooling solution target relatively low acoustic targets, at least for a blower fan cooled graphics card. 

AMD has released a community update for its Radeon 5700 series graphics cards, confirming that high (110°C) "hotspot" temperatures for their graphics cards is "expected and within spec". Furthermore, AMD confirmed that their designs will maintain the company's intended acoustic and reliability targets. 

With its Radeon Navi RX 5700 series, AMD has moved from offering a singular temperature sensor to offer multiple sensors that measure GPU thermals across the graphics card. This allows AMD's "hotspot" temperature to be the hottest part of the graphics card, enabling AMD to judge GPU thermals based on specific areas of the GPU, rather than a single location that AMD expects to be hottest. This design change enables AMD to get the most out of their Radeon RX 5700 series. Basically, AMD's new temperature monitoring solution enables them to offer as much performance as possible at stock. 
 
Users of AMD's reference RX 5700 and RX 5700 XT graphics cards should not be concerned about high "hotspot" temperatures, though those that desire better graphics cooling solutions could always opt for aftermarket designs from the likes of ASUS and Sapphire. 
 

    Junction Temperature: Enhanced Thermal Monitoring

In the past, the GPU core temperature was read by a single sensor that was placed in the vicinity of the legacy thermal diode. This singular sensor was used to make all power-performance optimization decisions across the entire GPU. However, depending on the game being run, the type of GPU cooling and other related metrics, different parts of the GPU might have been at different levels of utilization. As a result, ramping up or throttling down the entire GPU based on this single measurement was inefficient, often leaving significant thermal headroom – and resulting performance – on the table.

With the AMD Radeon VII GPU we introduced enhanced thermal monitoring to further optimize GPU performance. We built upon that foundation with the Radeon RX 5700 series GPUs, and now utilize an extensive network of thermal sensors distributed across the entire GPU die to intelligently monitor and tune performance in response to granular GPU activity in real time.

Paired with this array of sensors is the ability to identify the ‘hotspot’ across the GPU die. Instead of setting a conservative, ‘worst case’ throttling temperature for the entire die, the Radeon RX 5700 series GPUs will continue to opportunistically and aggressively ramp clocks until any one of the many available sensors hits the ‘hotspot’ or ‘Junction’ temperature of 110 degrees Celsius. Operating at up to 110C Junction Temperature during typical gaming usage is expected and within spec. This enables the Radeon RX 5700 series GPUs to offer much higher performance and clocks out of the box, while maintaining acoustic and reliability targets.

We provide users with both measurements – the average GPU Temperature and Junction Temperature – so that they have the best and most complete visibility into the operation of their Radeon RX 5700 series GPUs.

Yeah for anyone wondering it's almost impossible to damage the silicon with most transistor designs below 125 C in terms of actual physical temperatures (Obviously traditional temp readings are often a fair bit below actual temps because they couldn't traditionally embed the sensor in the chip itself).

While of course most damage from thermals is from thermal cycling (Quick heating and cooling cycles expanding and contracting the silicon) rather than stable high temps which are no problem at all really.Quote

Im sure they would have tested this and been confident the software knows how to handle the clock/temp situations or we would not have seen a release or driver updates if they had been concerned at all since release.
The media would have been all over this had there been high failure rates due to heat and thats the sort of publicity AMD does not need right now and they know it.Quote

While it's fine I still feel like AMD should have better stock coolers or at least a more expensive non air blower style card.Quote

Think of it this way -

They offer a 3 year warranty on these cards. That means they have to guarantee the worst case scenario for 3 years otherwise they can't be confident that they won't be inviting a slew of RMAs. That would mean 100% usage at the max allowed temperature for 3 years 24/7/365.

Most concerns with temperatures (at least at stock) are misplaced, usually the manufacturer has done all the hard work before they release it.Quote

GN has done a great piece on this and is well worth a watch and the AIB cards don't get anywhere near that hot!
