    Tell me about it. The numbers that I’m interested in - “decibels under full load”, “temperature at full load” - might as well not exist. Will I be able to hear myself think when I’m using this component for work? Will this GPU cook all of my hard drives, or can it vent the heat out the back sufficiently?

      Temperature is meaningless unless you want oc headroom. A watt into your room is the same no matter the temp the part runs at.

        That’s not correct, I’m afraid.

        Thermal expansion is proportional to temperature; it’s quite significant for ye olde spinning rust hard drives but the mechanical stress affects all parts in a system. Especially for a gaming machine that’s not run 24/7 - it will experience thermal cycling. Mechanical strength also decreases with increasing temperature, making it worse.

        Second law of thermodynamics is that heat only moves spontaneously from hotter to colder. A 60° bath can melt more ice than a 90° cup of coffee - it contains more heat - but it can’t raise the temperature of anything above 60°, which the coffee could. A 350W graphics card at 20° couldn’t raise your room above that temperature, but a 350W graphics card at 90° could do so. (The “runs colder” card would presumably have big fans to move the heat away.)

      I wish this was data was more available. I got a GPU upgrade 6800xt and it’s so loud. I can’t enjoy sitting at my desk without hearing a loud whine and a bunch of other annoying noises. Its probably because the card is 2nd hand but still.

        Maybe not cuz I have first hand 7900xtx and if I load it up it whines horribly lol.
