AMD’s Radeon RX 7900 XTX reference graphics card seems to have a important defect in its cooler style as pointed out by Der8auer.
AMD’s Reference Radeon RX 7900 XTX Cards May possibly Have A Defective Vapor Chamber That Causes Overheating & Prospects To Thermal Throttling
More than the previous 7 days, people began reporting a significant issue with the Radeon RX 7900 XTX ‘MBA’ reference graphics playing cards that brought on overheating and resulted in thermal throttling. This made reference types execute even worse because they were running at decreased clock speeds and whilst the initial response from AMD was that every thing was ‘Normal’ and declined an RMA to a purchaser, the business has now softened its place and questioned impacted people to get in touch with the aid staff.
Now in the 2nd online video posted by Der8auer on the overheating challenge, the tech qualified states that he has so far been given 48 this sort of confirmed cases and a handful of people even despatched him their playing cards for additional evaluation. Whilst it was earlier considered that removing and reinstalling the cooler and making use of suitable tension could correct the situation, that will not look to be the situation any longer and it is actually significantly even worse.
Der8auer examined the playing cards with a horizontal mounting, and a cooler mount to maximize the stress and even tried using replacing the spacer bolts and washers which is a little something that Igor’s Lab had proposed a working day ago in his individual results. But it appears to be like neither of these preset the overheating problem and the AMD Radeon RX 7900 XTX reference graphics playing cards continue to hit 110C Junction temperature. The flip approach did not even operate both.

All of this tends to make Der8auer conclude that the problem on the AMD Radeon RX 7900 XTX graphics card isn’t a straightforward mounting slip-up but a fault within just the cooler, more specially, the heatsink that makes use of a vapor chamber. Der8auer theorizes that the vapor chamber could possibly have a style or a substance issue that is avoiding the liquid inside of it from the right way flowing all around the card. Der8auer seems rather self-assured that the vapor chamber is the concern and that he will have a comply with-up video clip the place he dissects the block to see how the vapor flow is taken care of by it.

Now if it truly turns out to be a style and design flaw in just the cooler by itself, then AMD could possibly likely have to recall all Radeon RX 7900 XTX graphics cards because they absolutely usually are not developed within just spec and also are not operating underneath ‘Normal’ spec. AMD built quite a buzz all-around its Radeon 7900 coolers staying smaller and simple to up grade to but it appears to be like they neglected a significant flaw in the heatsink alone.
