This surprises me a bit after Tom's 280x roundup where the Asus DCII really came out nicely with regards to both acoustics and temps conceding in clocks to the faster but louder toxic card. Obviously this is a different chip with different properties, but fundamentally you'd expect mostly similar results with respect to TDP.
 
OK so the reason why this card is not performing through the roof :powerTune is keeping thermals AND power consumption in check.Now for a nice overclock to negate that effect and the 290 and 290x will perform through the roof.Wish I could afford one now... :(

To my point, and sorry for the double post:http://www.tomshardware.com/reviews/radeon-r9-280x-third-party-round-up,3655.htmlPage 12This operates on the assertion that the Toxic cooler for the 280x is quite similar to the 290x Tri-x, but that is conjecture. I'm sure there are subtle differences (though maybe those make all the difference in the case of the 290x).Page 6Subjectively the Asus sounds quietest to me in terms of the kind of noise it produces.Page 4,5Toxic is a good 8db louder as measured (and almost the loudest) but middle of the pack in relation to all the cards with regards to temps, and slightly cooler in temps than DCII and windforce by a few degrees.Page 2The Toxic is about 7% higher in clocks.The differences in the 290x are much more pronounced with the DCII and windforce losing in both aspects of temperature and noise. The open bench tests were more similar to the 280x tests which I assume were open bench, but the DCII and WF still came out ahead in terms of noise even in that test. Sapphire must really have reworked their Toxic cooler or this is a new design we didn't see on the 280x cards.

i think it should be included vrm temps in the article well i have hd7950 vapor-x the it have the worst vrm cooling i've seen temps in gaming is around 80°C on stock clocks(950/1250) and i'm getting this temps on very cooled case (cm haf912 with tree fans 2x200mm 1x140mm) so it will be very nice if you add vrm temps in your next review

Good article. I have also found from experience that good case airflow (i.e. well thought out directional airflow - not miscellaneous fans all over the place) can be much better at facilitating GPU cooling performance than open (and stagnant) air.MSI has IMO the best cooler out there in its Gaming series - I think they've struck the best balance of price, cooling performance & noise reduction of any card with this generation. I hope to see one in the round-up.On the CLC, do you have that setup pulling air into the case or exhausting out?

A computer case has two essential functions: housing the components and cooling them. The design of radial fans forcing airflow through a small aperture in the rear of the case is inherently less efficient (like pissing through a pinhole with the concomitant splash-back) than venting heat to the case interior. A well designed case will properly vent the heat and provide a good environment for the computer, a poorly designed case will trap heat and prematurely burn through components.I stress tested a GTX 470 with a shroud and radial fan and it ran about 20 C hotter than the (very same) GPU with a (dual axial fan) Zalman 2000 F under identical conditions in a Corsair 600 T case. Shame on AMD (and ASUS) for their design and the laziness of Gigabyte for being cheap.

Igor , I have to be honest, I think you did excellent due diligence for the article and compiled very good test results for us, thank you. However, reading the article gave me a really strong sense that you personally don't like the 290 series. I felt that was a little out of Tom's normal down-the-middle stance on reviews that has kept me a consistent almost-daily reader here for over a decade. Anyway, that's just my opinion. Thanks again for the great information.

The 1ms power consumption numbers look reasonable, albeit powertune shouldn't use such a fine setting to adjust clocks and fan speed. It would be interesting to overlay frame completion times with the high res power graph to see if anything else is going on there.

I have both of these cards. The Sapphire is a tremendously better built, better packaged card. At 100% fan speed, the Asus card isn't so much quieter as it is just a different tone. I actually prefer the Toxic. That said, I also paid >$100 more for the toxic card than I did the asus card.

Im curious if a side fan would have helped in a single card configuration. I know my crossfire setup (6850) likes to have a side fan blowing on the cards. Brings temps down a good bit when at full load, but idle stays about the same.

Is this the Gigabyte card that has been recalled?"Gigabyte:There is a problem with a heat sink. The production sample is different from the sample provided by our vendor. The sink for early media samples are not optimized to meet the design requirement. We will improve it immediately and we stop the mass production today."

Always liked sapphire for my graphics card and it seems this confirms it once more.Although I now run a 7950 msi 7950 (originally running the shitty stock amd cooling) of which I have replaced my cooler with an artic cooling one and I can tell you that cooler is still way ahead of any cooler those manufacturers put on the gpu.
