![]() ![]() I hope this post helped you out a bit & you can get your temps better under control. Here is a pic of what I have my fan curve set at, ![]() Now a lot of that is due the Windforce cooler on GB's xtreme models being a beast of a cooler but without a custom fan curve my temps would be much higher. For less demanding games or lower resolutions it usually sits in between 62C & 67C. The CPU temperature can be monitored by reading the core temperature sensors of Intel and AMD processors. The Open Hardware Monitor supports most hardware monitoring chips found on todays mainboards. Just for reference my 980ti running at 1508/2001 with 1.23v only hits 71C maximum on the most demanding games like Witcher 3 at 2k res with ultra settings (no hairworks). AMD Software: Adrenalin Edition provides users the ability to monitor the performance of their AMD Radeon Series Graphics and compatible CPUs. The Open Hardware Monitor is a free open source software that monitors temperature sensors, fan speeds, voltages, load and clock speeds of a computer. If you do already have a more aggressive fan curve set the culprit may be bad airflow in your case or a bad TIM application between your cooler & GPU on your 980. My suggestion to get your GPU's temps better under control would be to set a more aggressive fan curve through a program like MSI Afterburner or EVGA Precision X if have not done so already. IME with Maxwell chips ideally you want to keep them below 70C because that is where thermal throttling will begin, nothing crazy but it will knock your core clock down by around 15MHz at 70C & continue to drop the clock speed in small increments till you hit 84C where it will drop all the way back to it's base clock on the core. The factory set fan curves will usually allow NV cards to reach up to 84C where the GPU itself will throttle hard to cut back on temps. Are you running a reference or 3rd party model of the 980? Also have you ever set up a custom fan curve for your GPU or are still running it at factory specs? At factory specs (especially on reference models) the fan curves are set more with quiet operation in mind than cooling performance. TBH, I doubt v-sync or limiting FPS is the answer you are looking for to lower your temps, 75C does seems a little high for a GM204 chip. Although for a definitive answer we will have to wait for someone who knows more about this than I to chime in. I would be inclined to say that V-sync & limiting FPS do not act in the same way because of the performance hit v-sync has when turned on. I will say though IME (my display is 60Hz also) V-sync does help to keep temps under control in games that get well over 60FPS for me but makes no difference in temps if the game is running close to 60FPS with the resolution & settings I am using without v-sync or limiting FPS. Not sure about the difference between turning on V-sync & just straight up limiting your FPS to 60 since you have a 60Hz monitor. ![]()
