Against the backdrop of a large number of complaints regarding the overheating of Radeon RX 7900 XT / XTX video cards, well-known blogger and overclocker Roman “der8auer” Hartung conducted his investigation. We wrote about his findings in detail yesterday. Empirically, it was found that in a horizontal position, video cards warm up more, and the temperature of the Hot Spot quickly reaches critical values. der8auer suggested that the cause is in the evaporation chamber.
Igor Valossek from Igor’s Lab agrees with him. He received an anonymous comment about this from an OEM. Judging by his hints, this is a manufacturer of cooling systems. A company representative believes that we are talking about a defective batch of reference Radeon RX 7900 video cards. It is possible that at least one batch of Radeons with a evaporation chamber in which there is little liquid left the assembly line. Little condensate is formed inside the chamber and heat transfer is worse.
Igor Valossek also points out the problem of control, when it is possible to check the real performance of the evaporation chamber only after the device is fully assembled. At the same time, he has at his disposal a photo of an infrared camera with a Radeon test from the direct manufacturer, PC Partner, and everything is fine on them. However, the tests themselves took place in a vertical position and could relate to a different batch.
AMD has not yet commented on the situation. On separate complaints to technical support, users receive a response that 110 degrees is the normal mode for this product.
