I bought two Samsung 970 EVO Plus and two such radiators at once.1) The radiator that is close to the motherboard does not fit. Luckily, the motherboard had a well-functioning cap heatsink. 2) Install it in a vertical position. The large case fan blows directly above it, so I think the wind blowing heat away from the fins will be enough to cool it down. 3) In normal use, both discs will remain within a few degrees of each other. 4) I transferred 500GB from my Documents folder from the horizontal boot MB. At peak temperatures, the MB drive was 43Β°C (normal), the one "protected" by this heatsink reached 66Β°C (TOO HIGH buy, Samsung Magician report). this and try again. In fact, I probably won't leave it and I don't recommend it. 6) By the way, it took 10 minutes (with the case fan blowing directly) for the temperature to return to normal.
