Ko bi ga znal, na kraju bude ispalo da je do tvornice koja zapravo proizvodi te hladnjake ...

Obzirom da su sve to bili referentni modeli za recenzije, stvarno je moguće da su pogođeni određeni retail modeli ili je proizvođač tih hladnjaka sfušal određenu seriju i otišlo je u prodaju.

Igor Wallossek has provided a brief update to Der8auer findings. The possible issue being described is insufficient coolant added to the vapor chamber.

Igor does not want to spoil the der8auer’s new findings, so what is important is that the YouTuber is to share a new video tomorrow which should provide us more information.

Although the graphics card examined was an MBA design ("Made by AMD") affected by the temperature problems, Roman Hartung could not identify any obvious symptoms such as defects or design errors.

Eto, u prošlom videu je zaključak da AMD obavezno mora napraviti recall, jer je zahvaćeno sve pod Suncem, dok mu se u ovome sve čini OK.

Hotspot problem of AMD’s Radeon RX 7900 XTX (MBA): Even several batches of the vapor chamber affected, replacement of thousands of cards starts

However, I explicitly point out that all this information should be considered preliminary until an official statement from AMD and that there could still be corrections to the mentioned numbers. Of course, one can ask why all this was not recognized much earlier and why quality control obviously failed so grandiosely. This also has something to do with the fragmentation of production and supply chains. Both the chamber and the complete cooler come from a third-party manufacturer far in advance and are of course very difficult to test without the board assembled. If the PVT samples (Production Validation Test) worked, then later one takes samples from the current MP (Mass Production) at most. In the best case, such cards are tested e.g. at PC-Partner in special hot boxes, but are there in a vertical setup. And then it comes exactly to the occurred case, because the affected vapor chambers are not completely non-functional, but only more or less limited functional. However, this is almost impossible to monitor with granular tests.
