![]() The curious part is just how long MSI drags-out this ramp-up process. For the most part, the card would have you believe the default profile is to stick around 50% - but it just keeps steadily increasing, eventually stopping around 60%. The MSI RX 580 Gaming is an interesting duck when it comes to its fan profile, though. This limits the impact to frametimes in later testing, though we’re contingent on drivers and other actors as well. The frequency range is not greater than ~75MHz at worst, with most fluctuations sticking closer to 25-50MHz. noise (we won’t have time to run noise tests in time for this review, and will instead stick those into our XFX RX 580 review).Ĭlock dithering isn’t bad here, considering we’re just running the stock 100% power target. time and fan speed chart, which doubles somewhat as an indicator of temperature vs. Temp, Time, & FanĪbove is the frequency vs. ![]() The VRAM module runs around 68-70C, the middle of the VRM (MOSFET4) runs around 70C, and the back plate sees a dip in temperatures as the fans continue their ramping process. After an extended torture test in a power virus scenario, we rapidly learn that the fan profile is built to keep the RX 580 Gaming card’s GPU temperature to 70C, with frequency gating occurring alongside fan speed spikes to sustain that temperature. We’ve selected the middle-right VRAM module for this same reason – that tends to be where temperatures run high, given the proximity of the inductors and capacitor bank.Įverything’s fairly tightly packed. FET#4 was chosen as it is the center of the VRM, and so should run the hottest by nature of being surrounded by other hot components. It’s not the most impressive cooling solution we’ve seen, but there’s still contact via thermal pad to the heatsink from all core components. The first chart looks at GPU diode, FET4 (fourth from bottom), and VRAM temperatures (middle-right module) to better understand the cooling capabilities of the MSI Twin Frozr cooler on this card. These are the same methods we’ve deployed and refined since our EVGA VRM analysis, and just recently used to analyze the three 1080 Ti cards we’ve reviewed of late.Īmbient runs 26.6-28.6C during this test, but we actively measure ambient and apply calculations to offset competing numbers in comparative charts. Our thermal test methods are defined on the previous page, where we talk about how the FET, VRAM, & PCB backside temperatures are measured. MSI RX 580 Thermals: VRAM, VRM, & Silicon
