Need help with my Gigabyte 780 TI OC

[dayv]

I just bought my new computer ( specs:http://pcpartpicker.com/user/dragonuvvv/saved/XMH7YJ) And I have a feeling the GPU isnt doing very well. I have been playing a bit of BF4 and the GPU has been reaching upwards of 85 Degrees with 40% fan speed, which seems a bit high, I was wondering if this was normal. I just contacted Gigabyte support, havent replied yet, just wanted to get a second opinion off here. Thanks for your time.

However, unless you are actually crashing or have screen artifacts there's no reason to do anything. I'm not sure how you've determined this is too "high" of a temperature but modern GPU's do tend to run hot.

That what you can expect, simply turn up the fan or get more fans at least one to feed fresh air to the card

The Temp Limit on that card is 82c. That is the temperature that the card targets for its normal operating temperature. It will increase/decrease fan speeds, voltages, and Turbo Boost clocks to attain and maintain that target. So technically 85c with 40% fan is more or less normal, but with a Windforce cooler I would look into increasing your case airflow. I bet it's pretty hot where you live?

Appreciate the help 😀

The fan is auto-controlled though I suppose there are ways to change the profile (at the expense of noise).

I would suggest you monitor the GPU frequency using Gigabyte's or other software during gameplay of the more demanding games (the ones with most fan noise from your card) and see if the GPU frequency is falling much below your BOOST CLOCK speed.

For example, let's say your Boost Clock is 1085MHz and you note the GPU speed drops below 1000MHz. That could be because of two things:
1) You have VSYNC ON and you already get 60FPS thus the GPU doesn't need to work hard, or

2) Thermal management can't keep the GPU cool enough so you need more cooling (higher GPU fan, or better case cooling).
*So VSYNC would either be off, or it's ON but FRAPS reports less than 60FPS (or your target refresh).

In general, the GPU should be about its top frequency unless it's processing power is NOT needed due to a bottleneck (including VSYNC which is a software bottleneck) or if it's being throttled down due to a heat issue.

Case cooling can make a big difference. It doesn't need to be loud either. I have 2x12cm fans at the front as intake and another 2x12cm at the top/rear as exhaust. They are completely inaudible spinning between 500RPM and 700RPM depending on the temperature (PWM fans controlled by the motherboard via my fan profile).

Roughly speaking (depends on fan quality) a fan starts to make audible noise about 700RPM. For moving air out of the case it's better to have MORE fans spinning slower than LESS fans spinning faster.

A CPU liquid cooler can also remove the CPU heat if the radiator fans are set to exhaust thus reducing the temperature inside the case. I still prefer a good air cooler like the Noctua NH-U14S but that's based on my experience with areas that aren't too hot. I might have to rethink that for 30degC+ ambient temperatures, as well as CPU's that run really hot like an AMD FX-8350 or even a heavily overclocked Intel.

A SIDE FAN can also be handy to get more air flow across the graphics card. Again, it need not be super fast or loud though you obviously need a case that has this support and it can't interfere with the height of the CPU cooler (mine does).
