Hey I've had a Radeon 4870X2 for about 9 months. It's been working fine as far as performance goes, e.g. Crysis runs at smooth framerates as expected. And it hasn't given me any actual problems either, there's just something that I'm curious about. When I run for example 3DMark 06, and look at the temperatures in CPUID HWMonitor afterwards, there's a huge difference in temperatures between the two cores at full load, and a smaller difference when idle. Code: Min Max Core 1 55 C 84C Core 2 43 C 50C I bought the card used, its fan seems to be working fine. But is this normal? 34 deg difference between cores, really? Anyone else with 4870X2 who could share his temps? I have it in an Antec 900, with two fans at the front, one at the top-back corner and one big one above the CPU. All fans are set to low, but I do recall having the problem with the fans set to medium but I just never posted about it. I'm thinking there's three possible explanations: either one of the cores isn't performing at full capacity, or the other core is producing more heat than it should be producing, or the more heated core just happens to be placed in a position with significantly less air flow. I want to know if the last explanation is plausible because if it isn't there's something wrong with my card.
