EVGA GTX 760 Superclocked ACX reviewed

To cool the GTX 780 EVGA came up with the dual slot ACX (Active Cooling Xtreme) cooler. The card together with the cooler is 27cm long. With the ACX cooler EVGA took a step in the right direction, as it is perfect for enthusiasts keen to use the GTX 780 card in three-way or four-way SLI setups. Before we go further let’s see how it looks. It is a dual-slot, dual-fan cooler and it looks mean. You can find out more about the original GTX 780 ACX cooler here.

With the GTX 760 we got a new ACX cooler. The EVGA GTX 760 SC ACX is 24.5cm long, hence its cooler is a bit smaller than the original.

All ACX coolers we had a chance to try out use the same PLA09215B12H fans (90mm with 9 blades) made by Power Logic.

EVGA says that the blades used in the fans are up to 700% more rigid than fan blades used in competing fans, which also results in a 25% weight reduction. We’re not aerospace engineers, but the blades feel very tough indeed.

The fan uses a double ball bearing design which should last a bit longer and generate less noise even after a couple of years of wear. However, we noticed that one of the fans generated an unusual noise, but EVGA responded by promptly sending us a replacement card, as it deemed the first one defective. The replacement card worked like a charm.

This is what the bearings look like in real life, opposed to standard sleeve bearings used in most fans.

EVGA designed a special heatsink with a lot of dissipation surfaces. The heatsink was designed to minimize airflow turbulence between the fans using air barriers.

The ACX cooler for the GTX 760 comes with three 8mm thick heatpipes that are in direct contact with the GPU surface.

A part of the heatsink, i.e. the gray strip on the left, is in contact with the power components.

There’s an unusual addition under the heatsink, on the PCB. It’s the second baseplate which covers the almost completely empty PCB space at the end of the card. We’re really not sure why EVGA placed it there, since this part of the card has no memory modules or VRM components.
