Brian's suggestion to do some cleaning inside the case is the first thing you need to do. I don't know where you are physically located, but where I live we have had temperatures in the upper 90s F. These types of temperatures and a little dust in a strategic location can cause heating issue. I would also look for dust in and around the intake and exhaust fans in the case, these often neglected. When you blow out the CPU and the heatsink assembly you should place a pencil through the blades of the fan to keep it from spinning. I would eve go so far as to use Q-tips to clean out the heatsink.
The GPU has a maximum temperature of 97C. You have not provided any temperatures for this.
The CPU has a maximum temperature of 62C and will start throttling at 70C. You are encroaching on the maximum temperature for this CPU.
What are you using to determine these temperatures?
Just to get an idea of what is going on here please download and run CPUID's HWMonitorand post the temperatures and voltages seen there.
Thank you dc3 for the informed suggestions. I am currently using CAM software from NZXT to monitor temperatures. I didn't mention the GPU temperatures because they were nowhere near the CPU temps to even strike concern with me. They tend to say under 50C.
I am going to the store tomorrow and will pick up some compressed air cans and do a thorough cleaning of my PC and fans. I have stopped gaming on the PC for the meantime.
Also, on a sale, I ordered the Corsair H100i v2 liquid cooling system for my CPU and it will be here Friday. It was in the plans regardless if it helps resolve the problem.
I live in the countryside of Florida so I get lots of dust, heat, and humidity down here which is a constant battle for me as well as I have 2 German Shepherds (or better fitting, German Shedders) that are also part of the heat problem.
I am also looking into upgrading my GPU to this card: https://www.newegg.com/Product/Product.aspx?Item=N82E16814487266
It should be a nice investment for my gaming as well as the added liquid cooler should also help keep it cool as well.
Would it be wise to also invest in some nicer fans for the two liquid cooling systems and some aftermarket thermal compound? If so, any suggestions?
Thus far, my CPU has been a champ in performance until now should that be on my radar at all to upgrade in the future?
