So we expanded the scope of the testing to look at not just how the 7600X behaves with a basic air cooler, but also how the 65w Eco mode works, as well as the PBO2 curve optimizer, and we did all this testing with both the Wraith Spire and the 360mm liquid cooler. We decided that it might be entertaining to throw AMD's old Wraith Spire box cooler on the 7600X to see just how poorly it would run, and the results were extremely surprising and not at all like what we were expecting.Īround the same time we were trying to burn up our 7600X with AMD's box cooler, a lot of talk around Eco Mode started to surface as well as the PBO2 curve optimizer with a negative voltage. Shortly after completing our 7600X review we decided to do some testing and while we have significantly more Zen 4 cooling testing planned, this is an appetizer, a "for science" type test if you will. That's an insane temperature for a 6-core CPU using a 360mm AIO.īased on that alone, it's not crazy to assume that using an affordable air cooler performance will tank due to thermal throttling, which sees a reduction in operating frequency. After all, in our review of the 7600X we tested with the be quiet! Pure Loop 2 FX 360mm liquid cooler and the chip still peaked at 93C for an all-core workload. We've heard countless different takes on the matter and with this feature we want to hone in on the genuine concern that using anything less than a liquid cooler on the Ryzen 5 7600X would see a significant performance loss. AMD has addressed this by saying it's all by design and is intended, but that hasn't stopped the Internet from drawing its own conclusions and assumptions. One of the biggest points of contention with new AMD Zen 4 CPUs is their operating temperature, which is typically up around 95C. ![]()
