![]() ![]() ![]() This is unsurprising since this is only 14 degrees higher than the room's ambient temperature. Moving up to our AIO liquid coolers we can see one common trend, that load temperatures would simply not decrease below 34 degrees while under load under OCCT. More volts means more heat, so it is always best to use the lowest voltage that is stable.Īt stock setting all of the CPU coolers that we have tested were easily able to cooler our Ryzen 7 1800X, even our £36.95 Cryorig H7, which means that Ryzen 7 systems can easily be built with budget-oriented CPU coolers. These changes in voltages cause some strange results at stock settings, though it really does go to show the importance of fine tuning your CPU's core voltages when you want to control your load temperatures. This gave each CPU very different thermal results under load, with our 1800X presenting the lowest results due to the fact that it used the lowest core voltages at stock. With Ryzen, we found that stock voltages varied depending on your model, with our 1500X running at 1.31V, our 1600X running at 1.28V and our 1800X running at 1.22V under 100% load using OCCT. ![]() ![]() Why does the 1800X run cooler than the 1600X at stock? In our stock tests, we used 2666MHz memory, the highest that Ryzen officially supports, with our overclocked tests running at 3200MHz to provide more stress on the system. In this review, we have tested our coolers in a room temperature controlled environment and tested each CPU cooler with their stock fan configuration with their fans running directly from our system's power supply at both 12V and 7V (using fan speed reducers).Įach cooler will be tested on Windows 10 using OCCT to provide a heavy CPU load for half an hour, where we will use Ryzen Master to record CPU temperatures throughout testing. The highest measured temperatures are recorded on the graphs below.Īny CPU cooler that reached 70 degrees automatically failed our thermal test, though it is worth noting that no coolers reached this high threshold unless we overclocked our CPU. ![]()
