The heatsink is cooled by to top-mounted 90mm fans.
To maximize the dissipation area the heatsink was extended in all directions and reaches the edge of the PCB, which is also bigger than the reference PCB.
Looking at the back we see how huge this PCB really is.
We always advise users to clean the heatsink on a regular basis. It’s good for the card and it also helps keep fan RPMs as low as possible. We thought that removing fans and accessing the heatsink will be easy but it s not.
A single screw is to blame. It holds the plastic shroud in place and it can only be removed after the EVGA logo is removed. It can be done, and the logo can be slapped back, but we are not sure whether or not the logo will ever fit the car properly once this is done, especially in the long run. A single hole in the logo would have eliminated this ridiculous issue.
The fans can be cleaned without removing the entire cooler, you just need to undo three screws holding the fans in place. This is good news as it allows you to get better access to the heatsink without having to remove the shroud, so you should be able to clean the heatsink with compressed air, at least to some extent.
The entire cooler is attached to the PCB with four screws. As you can see the heatsink consists of two parts. EVGA calls this design the Dual Cooling Subsystem.
All GDDR5 memory modules are on the front side, and they are cooled by a special heatspreader which doubles as a reinforcement plate.
The company decided for advanced 14-phase power design (12+2).
The GTX 780 Classified features one standard HDMI connector (1.4a compatible), one standard DisplayPort out and two dual-link DVI outs. You can combine these connectors to setup a surround view.
Thanks to the dual slot cooler, it is easier for enthusiasts to chain up to two or more GTX 780 Classifieds.
