Hmm, looks like something went wrong there. I wouldn't be surprised if the performance suffered if all the 970 ACX models are like that.

Official EVGA response.
"The way the EVGA GTX 970 ACX heat sink was designed is based on the GTX 970 wattage plus an additional 40% cooling headroom on top of it. There are 3 heat pipes on the heatsink – 2 x 8mm major heat pipes to distribute the majority of the heat from the GPU to the heatsink, and a 3rd 6mm heatpipe is used as a supplement to the design to reduce another 2-3 degrees Celsius. Also we would like to mention that the cooler passed NVIDIA Greenlight specifications.
Due to the GPU small die size, we intended for the GPU to contact two major heat pipes with direct touch to make the best heat dissipation without any other material in between.
We all know the Maxwell GPU is an extremely power efficient GPU, our SC cooler was overbuilt for it and allowed us to provide cards with boost clocks at over 1300MHz. EVGA also has an “FTW” version for those users who want even higher clocks.
Regarding fan noise, we understand that some have expressed concerns over the fan noise on the EVGA GTX 970 cards, this is not a fan noise issue but it is more of an aggressive fan curve set by the default BIOS. The fan curve can be easily adjusted in EVGA PrecisionX or any other overclocking software. Regardless, we have heard the concerns and will provide a BIOS update to reduce the fan noise during idle.
Thanks,
EVGA"
In short they know it's a **** design and are trying to get out of it

Yeah we have seen EVGA statements like that in the recent past. Talking their way out of things. Laughable is all I can say.

Could it be that they used the same cooler thats on the 980 to cut down costs? Seeing that the 970 doesnt emanate as much heat,they thought it will do ok ...either way, d**k move.Curious to see how it looks on the 980.

All you need is a reference design card and a Arctic Accelero Xtreme 🙂
They are the Noctuas of GPU Cooling.

Damn. Evga is batting zeros.
You can see part of the gpu is coming in contact with the base of the cooler. It also looks like the gpu isn't even touching that third heat pipe. That's no bueno.

I just noticed that one of those heatpipes aren't even "complete" and doesn't extend all the way.
Wow EVGA, wow.

Wow that's a shameful display. Was leaning towards MSI anyways so going that route

Lmao eVGA -_-
What a joke

Fatum Force 😀 or Law of Karma
They make a mistake when they, took somebodys work
The EVGA Precision from Russian guy and they dont give him credit or some Money 😀
The Law of Karma -> Watch the movie HellRaiser
Maby they don't belive in Gods Force but It belives in Them :infinity:

BLEH!
Stock cooler's more than good enough, no?

For the record ... the third heatpipe isn't even functional as the one end is not even closed off.
