This build started in January of 2013 and has evolved over the past couple of years. In the beginning the case was a Corsair 500R and I was using a Galaxy GTX 680 HOF, which was a beast of a card for its time. After a year or so I decided to trade the 680 in for SLI GTX 770s, which worked great for awhile until I noticed that my setup was VRAM constrained in a few games (i.e. Skryim). So last fall I decided to trade the SLI 770s in for an EVGA GTX 970 FTW. The temps were great with the stock air cooler, but I had seen the NZXT Kraken G10 around the interwebs and thought it would be fun to try it out.
The Corsair H105 is probably overkill, but what the heck why not. I removed the stock air cooler, cleaned the stock TIM off of the GPU and the H105, threw a few heat sinks on the VRMs, applied some arctic silver 5 to the GPU, fitted the H105 into place with the G10 bracket, and I was good to go. The installation was relatively painless and took about an hour or so to complete with minimal jury-rigging.
The results so far have been great. I run the GPU with a +110/+500MHz overclock on the core/memory, which results in a boost clock of just over 1500MHz and 8000MHz effective memory. While gaming, the temps stay around 45 C +/- a few degrees (with all fans on their lowest setting using the NZXT Sentry Mix 2 fan controller), and everything is virtually silent.
Besides the GPU, the only other notable change I've made over the years is installing the two Crucial M550 256GB SSDs in a 512GB RAID 0 configuration, which nets me read/write speeds right around 1GB/s. The i7-3770k, Xigmatek SD1283, ASRock Z77 Extreme6, G.Skill Ripjaws Z, and the Seasonic X-750 have been constants throughout the evolution of my PC. All rock-solid, quality stuff, never had any problems with any of it.
