AMD CPUs, meanwhile, are generally a little lower around 90 degrees Celsius. Intel CPUs, for example, can generally hit temperatures as high as 100 degrees Celsius at the level of the processor die (the actual silicon wafer). Maximum temperatures for your components can vary. What Are Good Temperatures for Your Components? Even when doing some regular overclocking most of us don't need anything more than off-the-shelf parts since we are just trying to hit the moderate goal of exceeding 60 frames per second. Keeping the components super cool allows for greater performance improvements in order to hit world record speeds or unbelievable frame rates in games.įor the rest of us, however, a liquid cooler or solid fan will do just fine for keeping the CPU cool, and the graphics card's built-in cooling system is usually fine. If you watch an extreme overclocking event, you'll see enthusiasts use intense cooling methods such as pouring liquid nitrogen into a cooling pot above the CPU. Related: What Is Overclocking?

When things are staying cool the CPU and graphics card can either sustain their current performance for longer, or boost their performance even higher. When a PC component gets too hot it either triggers a system shutdown or, in extreme cases, a component ends up damaged. A computer's CPU and graphics card produce heat when in use, and thus you need some per-component cooling to keep things under control. Temperature is everything when you want to squeeze every possible ounce of performance out of your PC. That said, there are times when monitoring your PC case temperature can predict performance issues, though it's one of the last things you should be monitoring. Modern RAM usually does come with heatsinks covering the PCB (printed circuit board), however, and most motherboards include a heatsink for M.2 NVMe SSDs.Īs for the air temperature inside the case itself, as long as your components are cool that shouldn't be an issue. Everything else generally doesn't get too hot in most cases as evidenced by the fact that they don't have elaborate cooling systems. If you've ever had a cheap power supply die on you, then you will know it will also destroy your ram, motherboard and sometimes the hard drives too.It's easier to talk about CPU and graphics card temps since they have defined and well-known ranges. A quality power supply will cost you between $40-70 (USD) but it will almost certainly outlast everything else in your system, and has a greatly reduced chance of damaging ("frying") your components. It's not just about the number of watts, a quality 220w unit can outperform a 350w cheapo. In my experience this is one of the most frequent causes of random crashes in games and spontaneous reboots. A cheap power supply, like the ones you get for free with a minitower case, usually has poor power conditioning and will cause voltage dips in your computer. By using large fans they don't need to spin so quickly to move a decent volume of air, thus they are very quiet in operation.įinally, a component that isn't very obvious as a problem source could be your power supply. This push/pull combination ensures the air is constantly flowing and reduces fan resistance, improving their efficiency. One at the back pulling cool air inside near the processor, ram and video card the other at the front pushing air around the hard drives and through the vent holes. The fan in your power supply doesn't count.įor example I have added two 120mm Vantec Stealth fans in my system. If the temperature keeps rising while your PC is working, above this safe threshold, then you have a heat build-up problem and should install case fans to better circulate cool air throughout your system. It should stay within 10-15'C of your room temperature. Just be sure your probe is accurate, by testing it in ice water (zero celsius) and in boiling water(100 celsius).Īn indirect way to tell if your system is overheating is by watching the case temperature. To really know how hot your CPU is running, you would need to place a thermistor probe directly on the CPU die, or at least at the base of the heatsink as close as possible to the center. This will give you a temperature reading that is not very representative of the Athlon's thermal stress. Your motherboard's sensor is located underneath the chip, on the wrong side. Physically, an AMD Athlon can withstand up to 80-85'C before failing, but this is the temperature on the processor die. You can use MBM as directed by the other experts, but be aware that the temperature sensors built into the motherboard are very imprecise, they can be off by as much as 15-20'C.
