I'll do my best to check temps with my gun when I get home this evening. Side note, the boost PID in the attached graph is "wrong" because it's measuring MAP and doesn't account for atmospheric pressure so it's always showing high by ~14.7psi, at least using my OBD-II monitor (A discussion that would be better in the monitor thread). This wasn't reflected in the dash gauge which simply crept up and then didn't move. One other thing, when watching the OBD-II data I could tell exactly when the thermostat opened since it dropped fast and then stabilized over the next few miles. I'll have to whip out my laser temp gun when I get home and try to see what the t-stat housing temp reads compared to the sensor and dash. The oil pressure gauge on the dash is just an estimate from the computer based on RPM and oil temp. The 6.7L Cummins doesn't even have an oil pressure sending unit, it has an on/off switch. I've had other vehicles do this very thing for trans temp (Nissan Titan). If it's not working correctly, your system will heat up quickly, so be sure to check this regularly and replace immediately if it isn't working.Click to expand.I suppose that is possible, but based on history with other vehicles I'm more inclined to think the temp gauge is a "dummy" gauge and the computer has programmed to display one temp based on a range of coolant temps. If you don't have a case fan, your power supply's integrated fan is the only thing pushing hot air out of your system. If you install an 80mm fan in the front of your case and a 120mm fan in the back, the differential will create negative air pressure, and actually increase the potential for overheating.Įxternal cooling fans are also available for laptops, or simply resting your laptop on a cool pad can help keep temperatures in check. When adding case fans, make sure that the intake and exhaust levels match. For high-performance computers, you should install two: one to move cool air into the PC and another to carry the warm air back out. c. Adding a case fanĬase fans increase airflow to your components. Keep in mind, however, that your CPU fan can only cool to the lowest temperature in your case, regardless of how well designed it is. Upgrading to a better fan will help keep CPU temperatures down. Most CPUs come preinstalled with basic fans that are engineered to cool your processor just enough to keep it running – but nothing more. Your CPU is one of the most sensitive (and expensive) components inside your computer, so this is the first fan you'll want to look at. There's usually one on top of the CPU, one inside the power supply, and sometimes one or more on the front or back of the case.Īnd avoid using vacuums to clean – the static they produce often does more damage than the heat! b. Power down your computer and open your case, clean both the fans and their vents. You'll want to keep these free of debris using canned air to remove any build-up of dust and dirt. Now that we know some of the common causes of overheating, here are some ways to keep your PC or laptop cool.ĭust and dirt can wreak havoc on the first line of temperature defense: your fans. Multiple open browser tabs – having multiple browser tabs open consumes CPU and memory resources, which heat up as they are forced to work harder.Unresponsive programs – unresponsive programs consume excessive energy and memory as the PC tries to resolve errors.Outdated software – outdated, inefficient software can have a significant energy impact, especially for high-intensity tasks like gaming.However, if you were starting a typical room temperature (for PC labs) of 20-23C, then that would represent a +17C coolant gain. Some of this is addressed in the thread, but the supposed max coolant temp of 40C is not a fail point. Demanding applications – demanding applications, such as Adobe Premiere Pro, an overload to the CPU or GPU, can cause these components to heat up Your CPU will go to 50-60-70C and its fine.Fan failure – fan failure can result in inadequate heat regulation, leading to dangerous levels of overheating.Blocked air vents – obstructed air vents prevent hot air dissipation, causing heat buildup and increased internal temperatures.A hot environment – direct sunlight and hot environments can add additional heat stress that may overwhelm an internal cooling system.Here are some of the common causes of PC or laptop overheating: Vents, fans, and heatsinks are designed to help computers regulate this heat so that it doesn't damage your system's delicate internal mechanisms. Overheating occurs whenever the internal cooling system can't effectively ventilate the hot air caused by the hardware components processing your requests. Either way, you should also back up any documents, digital. You might experience overheating for multiple reasons, but understanding why your PC or laptop is getting hot is the first step to fixing the problem. Windows ME, it would also enable you to restore your entire working environment after a disaster. You might also hear the fan working overtime. If your computer is hot to touch, you may notice laggy graphics or slower than usual load times.
