Previously, I had upgraded my original Devil's Canyon (4690k) gaming rig (https://ca.pcpartpicker.com/list/jCgvGf) to a Kaby-Lake water-cooled setup (https://ca.pcpartpicker.com/list/XQqWgL).
Whilst I enjoyed the sheer prowess of my new setup, there was one major flaw with the build: the GPU. Now, you might say "But Fulcrous! You have a GTX 1070! How could it be the major flaw of your build?"
The answer is simple: the thermal performance of the GPU was poor. It would frequently hit 83 degrees Celsius despite the fans being manually set to 100% speeds. Whilst this wasn't a problem for titles such
as World of Tanks, more graphically intense games like FO4/PUBG/BF1 all took major hits due to the thermals whenever I attempted to stream. Even a mere Heaven Benchmark would result in the GPU reaching 80 degrees Celsisus +. So... after months of deliberation and procrastination, I finally decided to re-paste MSI's GTX 1070 Gaming X model.
Opening up the 1070 quickly revealed the problem: dried thermal compound.
Note: I had already removed the thermal compound off of the heatsink before I took the picture.
To make matters worse, the paste-job was far from sufficient, hardly covering any of the GPU. Roughly a 1/3 of the GPU was in contact with the thermal compound.
Fortunately, the re-paste process was simple. I used Noctua NT H1 as my thermal compound of choice and used the pea method for application.
The results? Well worth my time.
Running Heaven resulted in a peak of 63 degrees Celsius. A 20 degree Celsius drop from before.
I am very satisfied with the re-paste results; however I will have to see if the thermal performance is as great during longer sessions of testing/gaming.
Edit: Long-term gaming peaks at 67 C.
