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. Restart your computer and leave it to idle at Windows desktop for 20 minutes (to give time for CPU temps to stabilize).ģ.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. How to Check CPU Temperature in WindowsĢ. With two calibration points (Tjunction Max and Tjunction Idle), it is the most accurate CPU temp software for measuring core temps. If you're intending to overclock your CPU past the maximum safe temperature recommended by Intel or AMD, then we suggest Real Temp instead. It's an all-in-one temperature monitoring software - Besides checkingĬPU temperature, you can also monitor the temperatures of your hard.SpeedFan measures Tcase as well, its users have reported inaccurate It produces consistent and accurate temperature readings - While.Temp measures Tjunction, which can be confusing to novice users who are learning how to check CPU temperature. It measures actual CPU temperature (Tcase) - This makes its results.The good news is that there are a handful of excellent CPU temp software that you can download for free: Core Temp, HWMonitor, Real Temp and SpeedFan.Īmong these popular freeware, we find HWMonitor to be the best CPU temp software for most people due to the following reasons: What is the Best CPU Temperature Software? However, we do not recommend this practice as running a CPU at such high temperatures will shorten its lifespan over time. Therefore the goal of a hardcore overclocker is to push a CPU's speed as far as possible without going over its Tjunction Max. Tjunction Max is the highest temperature a CPU will tolerate before it throttles (lower its clock speed to prevent overheating). While Tjunction is of little concern to most people, serious overclockers do need to pay attention to their CPU's Tjunction Max (or TJ Max). Tjunction (also known as TJ) is the CPU core temperature, measured by a digital thermal sensor DTS located within each CPU core. It is useful for determining your CPU's idle temperature, normal temperature and maximum temperature. In short, Tcase is the only temperature that most computer users should bother with (unless you intend to overclock heavily). When Intel, AMD and tech articles mention "CPU temperature", they are referring to Tcase (unless otherwise stated). This temperature is measured by a diode embedded between the CPU cores. Tcase is CPU temperature measurement taken from the center of the CPU's top But no worries we're here to explain everything in plain English and clear the air once and for all: Difference Between CPU Temp and Core TempĬhecking CPU temperature is supposed a straightforward affair, but the varying definitions of CPU temps have confused many people (and techies).
