When it comes to dealing with peak usage, the maximum CPU and GPU temperature of any computer system is an important factor. This is especially true when overclocking or running high-end applications that require a great deal of power. While the exact temperatures for any particular computer setup are dependent on several factors, such as cooling solutions and ambient temperature, generally speaking, most CPUs and GPUs should not exceed 80°C during peak usage. To ensure that temperatures remain within this range, users should consider investing in additional cooling solutions or limiting their overclocking activities.
