Is it fan related, Daytona King?
nope, I've opened the case and tried to determine where it came from. Ran several tests with the MSI tools called afterburner and kombustor which can load the GPU as like in a game, and checked when the crackling sound started. It starts when the card is on load, and if with afterburner I reduce the card's clock speed, the noise reduces too (but doesn't go fully away). The instant I close the 3D test, the noise goes away too.
So it's definitely not a fan, it's rather something electric, maybe the so called "coil whining". But with high quality MSI cards this isn't supposed to happen, as they state they use "military class components".
Or it's either the PSU (ANTEC TP-750) that isn't powerful enough to feed the beast at full charge and therefore whines when trying. The GPU draws 40A at full load, but my PSU only has a max output of 25A per +12V rail. The GPU has two power connectors, each connected to a separate +12V rail on the PSU, so in theory it should be good, but I've seen on the MSI forum that it's better to have power drawn from one 40 or + amps capable rail than separate smaller rails... so it might be that I need a better PSU.
We'll see what the vendor says.
