Another review of the DCUIIGuru3d ASUS GeForce GTX 780 DirectCU II OC review
Cooling & Noise Levels
The NVIDIA reference coolers are great, but they follow the temperature target of 80 degrees C. With the DirectCU II, CoolTech Fan technology the GPU will get 425W of cooling power thrown at it. As a result the temperature target might remain 80 degrees C, but we have never seen the card pass 66 Degrees. An added benefit of that is that the dynamic clock frequency will go higher up to the point it reached its power target. So this is why the card is so close and sometimes a small notch faster then the GTX Titan. Noise wise I (and I am truly nitpicking here) I expected total silence. Fact remains that you can hear a bit of airflow when the GPU is under stress. Now it's close to nothing, but after reading all the marketing gobble on CoolTech Fan technology I expected the cooler perform bar nothing or at least get Parrot AR drone functionality
But it remains a cooling solution that can be compared to the competition in terms of performance. Overall though, the cooling solution is really good, no mistake there.
Thanks for posting this. I'm ready to buy TODAY but the EVGA and this one remain elusive.
NP, im still searching for myself, if i find more info ill continue posting it. Hope you can get a hold on the EVGA ACX has decent comments, maybe SPCR could review one in the future.
Personally im a little disappointing into Asus DCUII, but i can see why they did it, with the GTX780 boost 2.0 based on temp... a lower temp running videocard will perform better. But i was just looking for the same quietness of the GTX680/670 series with a little better performance, im still unsure what to do atm. I would love to see SPCR get a hold of one of those, since they have reviewed multiple Asus DirectCUII cards in the past year.
I'm kinda wanting to wait how the MSI GTX780 Lightning, it was shown on a shadowed boxed on Computex but not displayed, so idk if its still very far away from release. In my experience the twin frozr IV is quiet on idle and mid load still quiet, but at high loads becomes really loud, to drive it to that point only furmark can, normal gaming still is very quiet in my limited experience with GTX660TI. MSI is suppose to release the twin frozr V with the GTX780 lightning.... but unsure if its going to be quiet or more like asus aimed into better cooling for the boots 2.0.
I'm also thinking with such a good reviews on the Asus DirectCUII on GTX680/670, specially from SPCR, that i should accept lower performance and save some $$$, and just go for the ASUS GTX770-DC2OC-2GD5 GeForce GTX 770 2GB 256-bit GDDR5 PCI Express 3.0 HDCP Ready SLI Support Video Card
, its practically the same card and same cooler as the ones reviewed on SPCR, just a little higher clocks, so it should be good in theory, just 20% slower than GTX780, still i don't think a single GTX780 will drive a 4k monitor, not sure if 2 will, so i might just wait for nvidia maxwell next year for planning a 4k setup, and just call it with sure bet on quietness on the Asus GTX770 DirectCUII.
