The new EVGA GTX 1080 FTW2 with iCX Technology
Back in November of 2016, EVGA had a problem on its hands. The company had a batch of GTX 10-series graphics cards using the new ACX 3.0 cooler solution leave the warehouse missing thermal pads required to keep the power management hardware on its cards within reasonable temperature margins. To its credit, the company took the oversight seriously and instituted a set of solutions for consumers to select from: RMA, new VBIOS to increase fan speeds, or to install thermal pads on your hardware manually. Still, as is the case with any kind of product quality lapse like that, there were (and are) lingering questions about EVGA’s ability to maintain reliable product; with features and new options that don’t compromise the basics.
Internally, the drive to correct these lapses was…strong. From the very top of the food chain on down, it was hammered home that something like this simply couldn’t occur again, and even more so, EVGA was to develop and showcase a new feature set and product lineup demonstrating its ability to innovate. Thus was born, and accelerated, the EVGA iCX Technology infrastructure. While this was something in the pipeline for some time already, it was moved up to counter any negative bias that might have formed for EVGA’s graphics cards over the last several months. The goal was simple: prove that EVGA was the leader in graphics card design and prove that EVGA has learned from previous mistakes.
EVGA iCX Technology
Previous issues aside, the creation of iCX Technology is built around one simple question: is one GPU temperature sensor enough? For nearly all of today’s graphics cards, cooling is based around the temperature of the GPU silicon itself, as measured by NVIDIA (for all of EVGA’s cards). This is how fan curves are built, how GPU clock speeds are handled with GPU Boost, how noise profiles are created, and more. But as process technology has improved, and GPU design has weighed towards power efficiency, the GPU itself is often no longer the thermally limiting factor.
As it turns out, converting 12V (from the power supply) to ~1V (necessary for the GPU) is a simple process that creates a lot of excess heat. The thermal images above clearly demonstrate that and EVGA isn’t the only card vendor to take notice of this. As it turns out, EVGA’s product issue from last year was related to this – the fans were only spinning fast enough to keep the GPU cool and did not take into account the temperature of memory or power delivery.
The fix from EVGA is to ratchet up the number of sensors on the card PCB and wrap them with intelligence in the form of MCUs, updated Precision XOC software and user viewable LEDs on the card itself.
EVGA graphics cards with iCX Technology will include 9 total thermal sensors on the board, independent of the GPU temperature sensor directly integrated by NVIDIA. There are three sensors for memory, five for power delivery and an additional sensor for the GPU temperature. Some are located on the back of the PCB to avoid any conflicts with trace routing between critical components, including the secondary GPU sensor.

For many of you reading this, the temperature outside has fallen to its deepest levels, making it hard to even bare the thought of going outdoors. What would help out a PC enthusiast and gamer in this situation? Some new hardware, delivered straight to your door, to install and assist in warming up your room, that's what!
PC Perspective has partnered up with EVGA to offer up three amazing prizes for our fans. They include a 750 G2 power supply (obviously with a 750 watt rating), a Z170 FTW motherboard and a GTX 970 SSC Gaming ACX 2.0+ graphics card. The total prize value is over $650 based on MSRPs!
All you have to do to enter is follow the easy steps in the form below.
We want to thank EVGA for its support of PC Perspective in this contest and over the years. Here's to a great 2016 for everyone!
EVGA GTX 750 Ti ACX FTW
The NVIDIA GeForce GTX 750 Ti has been getting a lot of attention around the hardware circuits recently, but for good reason. It remains interesting from a technology stand point as it is the first, and still the only, Maxwell based GPU available for desktop users. It's a completely new architecture which is built with power efficiency (and Tegra) in mind. With it, the GTX 750 Ti was able to push a lot of performance into a very small power envelope while still maintaining some very high clock speeds.
NVIDIA’s flagship mainstream part is also still the leader when it comes to performance per dollar in this segment (for at least as long as it takes for AMD’s Radeon R7 265 to become widely available). There has been a few cases that we have noticed where the long standing shortages and price hikes from coin mining have dwindled, which is great news for gamers but may also be bad news for NVIDIA’s GPUs in some areas. Though, even if the R7 265 becomes available, the GTX 750 Ti remains the best card you can buy that doesn’t require a power connection. This puts it in a unique position for power limited upgrades.
After our initial review of the reference card, and then an interesting look at how the card can be used to upgrade an older or under powered PC, it is time to take a quick look at a set of three different retail cards that have made their way into the PC Perspective offices.
On the chopping block today we’ll look at the EVGA GeForce GTX 750 Ti ACX FTW, the Galaxy GTX 750 Ti GC and the PNY GTX 750 Ti XLR8 OC. All of them are non-reference, all of them are overclocked, but you’ll likely be surprised how they stack up.
