We got a brief glimpse of EVGA’s new iCX cooler last month during CES, but the company hasn’t revealed much since. Now, EVGA is breaking the silence with full details about the cooler, the graphics cards it will be available on, and its availability. We got a chance to go deep on the new tech, which you can read here.
EVGA announced its ACX 3.0 cooling solution back when Nvidia revealed the Pascal-based GTX 1080. Since then, the company has applied the ACX 3.0 solution on several of its Pascal models, the latest being the GTX 1050 and GTX 1050 Ti. However, many owners of GTX 1070 and 1080 FTW cards experienced thermal issues; sure enough, we found that this stemmed from inadequate cooling around the VRMs and memory. EVGA promptly issued a BIOS update for the affected cards as well as free thermal pad kits.
This fiasco has died down somewhat, but it raised new questions regarding the way EVGA (and graphics card vendors in general) monitor temperatures. Currently, monitoring software detects only the GPU temperature, and we base our fan speeds on that. Meanwhile, the rest of your graphics card’s temperatures go undetected. Nvidia’s Pascal GPUs have plenty of horsepower to offer while remaining relatively cool, but the same can’t be said about the memory or the PWMs.
To address this, EVGA is introducing iCX, which the company touts as “more than just a cooler.” iCX stands for “Interactive Cooling Xtreme,” and its motto is “Peace of Mind Gaming.” To achieve this, not only has the cooler shroud been redesigned, but so has the PCB. The new PCB features nine temperature sensors: three for memory, five for PWM, and one for the GPU. All of these temperatures are monitored independently within EVGA’s Precision XOC software.
The cooler shroud itself features two fans that run asynchronously, or rather, the fans run independently of each other based on the graphics card’s GPU, PWM, and memory temperatures. The primary fan is controlled by the GPU’s temperature, whereas the secondary fan is controlled by the PWMs and memory. If the sensors detect a low GPU temperature and high PWM and/or memory temperatures, the first fan will slow down while the second fan maintains a higher RPM.
Besides the fan curves, users can also create custom RGB profiles based on the detected temperatures. The shroud features RGB indicator displays: G, P, and M, which correspond to GPU, PWM, and memory, respectively. The G, P, and M backlighting will change depending on how you configure your settings in Precision. The example below depicts the backlight glowing blue when a component measures between 20 and 60° C, glowing green above 60° C, and finally glowing red when temperatures reach 83° C.
The new iCX cards have die-cast baseplates and backplates. In addition to providing rigidity, the baseplate and backplate act as heatsinks by making direct contact with the components. The baseplate features interlaced pin fins that provide additional heat dissipation, whereas the backplate is divided into two pieces to prevent heat from the PWMs and memory from spilling over to the GPU (and vice versa).
The heat fins received a facelift as well; half of the fin array consists of L-shaped fins that make direct contact with the components while the other half remain open to direct the airflow. Small holes have been punched into the fins provide additional airflow. Finally, a safety fuse has been integrated into the PCB that will blow should the temperatures ever reach a critical point. The shroud won’t be compatible with current SC and FTW PCBs, but it will fit on EVGA’s Hybrid models.
To kick off iCX’s unveiling, EVGA has announced the GTX 1080 FTW2 iCX, which will be available immediately. In addition, iCX will be featured on all of EVGA’s 10-Series lineup in SC2 and FTW2 flavors. Moving forward, EVGA still plans on offering ACX cards, with iCX cards being offered as a premium alternative. Finally, the company has also announced a $99 ACX-to-iCX upgrade program for current ACX 3.0 card owners.

The GPUs weren't defective, the cooler was only sometimes inadequate for some people's OCs if they happened to win the GPU lottery and also push that lucky GPU to its max.
Which admittedly works fine. However they should have left well enough alone, this will just leave a bad taste in everyone's mouth. Offer the program to everyone, or no one.
VRM quality and cooling been an issue with the SC line since the 5xx series. If there's a good thing to come out of the 1070 / 1080 SC / FTW fiasco, it's that EVGA is finally paying attention.
you sure?
i just stepped up my thermal pad fixed gtx 1080 gaming sc (6183) to an ICX sc2.
the only reason i did it was because i lost the silicon lottery on my replacement card. it wouldn't go past 1960mhz.
and also i fear my ACX 3.0 card will lose significant value over time.
the $99 did leave a sour taste in me tho, it was quite expensive considering i'm already down $650 for the 1080.
I still plan on calling them anyways to find out whats going on. However on the EVGA forums MODs and support are indicating only reference cards?
The system will not allow me to step up to P/N: 08G-P4-6686-KR which is the FTW2 card the redesign of the 6286 model. Any help would be much appreciated.
Its worth noting that i do have the option to "Step Up" but all the cards listed are lower tier compared to my original card.. I just want to switch my FTW to FTW2. don't want a time bomb 4 - 5 years down the road.
