Thermal Properties, Noise & Overclocking

The thermal properties of the EVGA GTX 1080Ti SC2 ICX are simply outstanding for a two fan video card of this magnitude. 

Idle

GPU-Z is showing a core temperature of 50oC as is Precision XOC, GPU-Z is limited to core thermal readings Precision XOC gives us the full inventory of readings.

After a half hour run of MSI Kombuster's Furry Torus we had a core reading of 65 oC, the VRM's were hitting 64-66o C and our memory was running 63-67o C and that single image should show you the power and long overdue functionality of iCX technology. Yes, it cost a few bucks more but well worth it!

Noise

The only noise coming from our test rig consists of 3 fans on an EKWB triple radiator cooling system with fans set so low as to be inaudible. From 3 feet distance between the noise meter and the EVGA GeForce GTX 1080 Ti SC2 GAMING iCX we got a reading of 27dBA at idle. Load the EVGA GeForce GTX 1080 Ti SC2 GAMING iCX got up to 36dBA which is darn good considering it's a 2 fan video card. We have no complaints about fan noise and the cards fans shut down completely when the SC2 is below 60o C.

Overclocking

Let's start with a stock speed shot of GPU-Z.

EVGA GeForce GTX 1080 Ti

The stock speed shot of GPU-Z shows us a core speed of 1557MHz and a memory speed of 1376MHz(real) or 11,008MHz effective.

We got a +97MHz core OC and moving up to +102MHz we got driver issues but let's face it running a throbbing 3584 Cuda Cores the OC becomes a pretty minor factor. The memory we bumped to 1410MHz from 1376MHz or 11280MHz effective and we did the OC with fans on stock settings. We would suspect you can get a few more MHz setting the fans higher.

OC Effect

Now you can hit a sweet 200MHz core OC but you really need to check and see if it's a productive OC or if you've merely got OC and a core starved for voltage yielding a loss in FPS.

EVGA GeForce GTX 1080 Ti

We backed up a tad on the CPU OC to 4.8GHz to eliminate and ragged edge CPU OC variance and the EVGA GeForce GTX 1080 Ti SC2 GAMING iCX pushed out 170.69 FPS.

EVGA GeForce GTX 1080 Ti

Our OC got us a healthy bump in FPS up to 197.57 FPS or 26.88 FPS increase. We could wind the memory on the EVGA GeForce GTX 1080 Ti SC2 GAMING iCX a little tighter but gains beyond our OC were minimal. Different tests might yield different results with a little faster memory but keep in mind this is a $769 (NewEgg) investment so you may want to consider longevity.

EVGA GeForce GTX 1080 Ti

Here's what EVGA Precision XOC shows, +97 Core, +136 Memory, 110% Power Target and 87oC Temp Target with the priority set to 110% power. Yes, we tried 120% and max temp target but Pascal's design isn't about brute force OCing, at times more voltage can just heat up the core and neuter your OC.
