Hi all!
Earlier this week, I finally got around to making my first build! I'm pretty happy with how it turned out, and have been using it for the past couple of days. Unsure if relevant, but the part list is here.
For CPU cooling, I decided to stick to the 3700x's stock cooler. When I first tested the build, I used the onboard thermal pad. I then had to transport it, so I took everything apart and cleaned the thermal paste on both the cooler and the CPU with IPA (Isopropyl Alcohol). When I reassembled the build, I used some IC Diamond 7 Carat Thermal Compound. Case cooling is the 3 fans that came with the case as intakes and the 3 RGB fans I bought as exhausts (case thermals reach equilibrium around 40C).
Now, to make sure my cooling was good, I used HWinfo64 to monitor. I logged the results, and saw that the CPU temps where hovering between 70 and 80, commonly reaching mid 90s. I was doing some light programming and I played a bit of Fortnite during the time of logging. The thermals and clocks are in the graphs below. As a sanity check, I ran the logging a total of three times, all with similar results.
AFAIK, this behavior is not normal. Any ideas what could be causing such a hot CPU? Right now, with a few browser tabs open, it's around 70C. The return policy for the CPU is valid for one more week, should I consider exchanging it?
