Hey, TheSLSAMG here. I use a Gigabyte GTX 770 2GB Windforce in my main rig, and I was wondering about the cause of my temp issue is (my GTX 770 loads at 80-84C, even after changing the thermal paste) and if an NZXT Kraken G10 and Thermaltake Water 2.0 Performer would both reduce temps and be compatible. Thanks.
The GPU can take that temperature without issues, but if you still want to lower the temperature then perhaps it's rather the case cooling that would be best to improve a little. Changing out the cooler is not worthwhile.
If it bothers you, you can set a more aggressive fan profile in a program like MSI afterburner.
You can use it with non-MSI cards fine.
I keep mine around 70-75c, but I have a different cooler. I have the Asus 770.
How many case fans do you have?
Avoid the G10 as it will shorten the life of the card, as its design fails to properly cool the VRM's and RAM, while also not leaving enough space to attach a useful heatsink to the components.
videocards are traditionally designed to run at higher temperatures as they have less space to work with. The higher the delta between the GPU temperature, and ambient temperature is, the more heat the heatsink is able to dissipate This is also why a car or SUV radiator does not perform much better than a 200-300mm radiator when cooling a single CPU, the cooling performance drops exponentially as you get closer to ambient temperature.
Be designing the card to run at higher temperatures, a small heatsink can better handle a high TDP, where as if they wanted the card to run at 40-50C range at full load, they would need a heatsink that is multiple times larger.
With your card, depending on your cooling design, a traditional airflow design may not be optimal. For example a very long card can significantly disrupt the airflow of the case. For best performance on cards like this, it is often best to have 2 channels of airflow, one leading directly to the CPU area (with a clear shot at the motherboard as the VRM's and chipsets are designed to get their airflow from the case fans)
Then a side panel to provide additional airflow to the videocard and get rid of any pocket of hot air caused by a long card restricting airflow around the inside of the case.
