Pros: Quiet: The ACX cooler is quiet enough to not disturb the gaming ambiance with fan noise. Also the card I received has no perceptible coil whine.

Coming from a R9 290X which audibly buzzed during gaming and squealed on menus with no V-SYNC this is awesome.

During gaming cooler is Sub 40 decibels, maybe mid to high 30's which with headphones or speakers during gaming is almost imperceptible.

Cons: Lit up logo on the side of the card - option to turn off please.

Other Thoughts: Coil whine is not inherent to high end graphics cards - it is either your PSU, GPU, or a combination of the two together. Don't live with it if you don't want to!

Really like this card, good job Nvidia.

Pros: I installed the Arctic Accelero Extreme IV on a Visiontek R9 290x with revised heatsink, and it works great.

Essentially if you have a R9 290x with a "2nd gen heatsink" like on my card, there will already be heatsinks on VRM chips and Ram and a passive cooling backplate from the factory. This allows you to skip installing the backplate from Arctic, and the factory installed heatsinks will work in with the Arctic Accelero.

Load temps in low 60's with fan set at 75%. I would strongly advise manually adjusting the fan speed to the highest percentage your ears will allow. 100% is a little noisy - 60% is quiet, and somewhere in between works great when your gaming with sound to cover the fan noise.

Cons: One of the gpu mount screws stripped, but still worked enough to mount cooler.

Metal bracket surrounding the coolers "cold plate" the part that touches the gpu, flexes under very little screw tension.

Essentially I think the cooler and screws are made from junk metal. All different grades of steel are available, and it seems Arctic has saved some pennies here. Really not a surprise, and doesn't present much of a problem, but the cooler might not fare well from multiple installations/ switching cards down the road.

Other Thoughts: If you have a reference cooled R9 290x, pick up some heatsinks for the VRM and Ram chips, for a little extra headroom. Cooler will probably work without them, but overclocking the Ram etc. could present problems.
