Gigabyte GeForce GTX Titan Black: Do-It-Yourself Cooler Swap

Power Consumption: Gaming And Full Load Measurements

Gaming Power Consumption

The next two diagrams represent before and after our modification, represented by a gaming workload.

When we look at cards based on AMD's Hawaii GPU, power consumption drops massively when we encounter a more effectively-cooled board. This is a result of lower leakage.

Here, we see the opposite as power consumption increases quite a bit. The main reason is that throttling is more deftly avoided, since the GPU falls well under Nvidia's thermal target. The card’s efficiency doesn’t get any better, but available gaming performance does increase by about the same percentage as power consumption.

Power consumption on the 12 V rail through the motherboard's PCI Express slot is relatively constant. The memory subsystem's power consumption increases a little. Really, most of the increase is measured at the auxiliary power connectors. 

Because it stays under Nvidia's defined temperature limit, the modified GeForce GTX Titan Black approaches its 250 W TDP.

Stress Test (GPGPU) Power Consumption

Here's where we push this card to its limit. Since Gigabyte's GeForce GTX Titan Black hits its power limit in both cases, and the load is constant as well, there aren’t as many peaks in our graph.

It’s particularly interesting that power consumption and compute performance are almost identical under full load. In other words, workstation users buying the card exclusively for its compute potential won't benefit from a better cooler. I can’t resist the temptation to mention AMD's FirePro W9100 (AMD FirePro W9100 Review: Hawaii Puts On Its Suit And Tie), which could have beaten Nvidia’s Quadro K6000 in more of our tests if it was equipped with better cooling.

    So we have to change the cooler by our self? now thats wierd.

    If you bothered reading the first page you'd know why.

    "Nvidia doesn’t allow its partners to sell the GeForce GTX Titan Black with proprietary cooling. However, Gigabyte now offers a GHz Edition of the card that comes bundled with its WindForce solution, which you can install on the overclocked board yourself."

    This one right? whats the difference between you install it yourself and Gigabyte take the initiative pre-factory installed? or Warranty Void?

    It is one of Nvidias funny rules.

    Ok, for your better understanding:
    Nvidia doesn’t allow its partners to sell the GeForce GTX Titan Black with factory-installed proprietary cooling.

    If you are dropping the cash on a Titan I really wish people would go liquid cooling. Seems to be the best.

    Nvidia doesnt permit to install any 3rd party cooling on their chip, now thats weird !

    That's some way to circumvent nVidia's rule. Nicely done Gigabyte!

    Very nice, Gigabyte! I almost wish I had bought one. I have one of those "out of stock ASUS cards from Newegg". I am not disappointed, though. The card handles 84 degrees Celsius just fine!

    Igor Wallossek, I wonder if you could put up a graph for 3D rendering? If you use Blender's BMW scene by Mike Pan (a popular benchmark scene), make sure you properly set the tile size!

    Silly question probably, but why does nVidia allow only EVGA to break this rule, with their hydro copper signature edition you mentioned? Is it just because it's a water cooled model? Do you think nVidia specially signs off on the design?

    I'm genuinely curious.
