Why does a question about CPU overheating warnings pop up so often?
I recently swapped out my Intel i5-9400f for an Intel i7-9700 at 3.00GHz, but I didn't change the Cooler Master Hyper TX3 EVO CPU cooler. Now, sometimes my computer starts up with a CPU overheating warning. If I turn it off and let it cool down for a few minutes, the warning disappears. What could be causing this and how do I fix it?
When you are trying to fix something with a thread, it is normal to give details about what your whole computer looks like. Please write down all of these things: CPU, Cooler, Motherboard, RAM, Hard Drive or SSD, Graphics Card, Power Supply Unit, Case, Operating System, and Monitor. You should also mention how old the power supply is, not just the brand and model name. Make sure to tell us which version of your motherboard's BIOS you have right now. If the inside parts haven't been changed since they were made, it might be a good idea to unplug the computer from the wall, open the side panel, and clean out everything that is inside. Dirt and dust could stop your CPU cooler from working well at taking heat away. The air holes in the case might also get blocked up, which stops the computer from pulling in cool outside air.
You installed a stronger/hotter processor. The TX3 cooler is a basic push pin cooler that is no better than the stock intel cooler. I would replace the TX3 with a decent cooler. Perhaps $50 or so. But, since you had to remount the cooler during the processor swap, you may have not secured it level. With power off, nudge the cooler to see if it wiggles. Check the back of the motherboard to verify that all 4 push pins are through the motherboard and locked. To that end, here is my stock answer on how to do it: ----------------how to mount the stock Intel cooler-------------- The stock Intel cooler can be tricky to install. A poor installation will result in higher cpu temperatures. If properly mounted, you should expect temperatures at idle to be 10-15c. over ambient. To mount the Intel stock cooler properly, place the motherboard on top of the foam or cardboard backing that was packed with the motherboard. The stock cooler will come with paste pre applied, it looks like three grey strips. The 4 push pins should come in the proper position for installation, that is with the pins rotated in the opposite direction of the arrow,(clockwise) and pulled up as far as they can go. Take the time to play with the pushpin mechanism until you know how they work. Orient the 4 pins so that they are exactly over the motherboard holes. If one is out of place, you will damage the pins which are delicate. Push down on a DIAGONAL pair of pins at the same time. Then the other pair. When you push down on the top black pins, it expands the white plastic pins to fix the cooler in place. If you do them one at a time, you will not get the cooler on straight. Lastly, look at the back of the motherboard to verify that all 4 pins are equally through the motherboard, and that the cooler is on firmly. This last step must be done, which is why the motherboard should be out of the case to do the job. Or you need a case with a opening that lets you see the pins. It is possible to mount the cooler with the motherboard mounted in the case, but you can then never be certain that the push pins are inserted properly unless you can verify that the pins are through the motherboard and locked. If you should need to remove the cooler, first run the cpu to heat it up and soften the paste before shutting down and powering off the pc. That makes it easy to unstick the old cooler. Turn the pins counter clockwise to unlock them. You will need to clean off the old paste and reapply new if you ever take the cooler off. Clean off old paste with alcohol and a lint free paper like a coffee filter. Apply new paste sparingly. A small rice sized drop in the center will spread our under heat and pressure. It is hard to use too little. ----------------------------------------------------------------------------------
Hey there! I think this might be about the cooler placement or thermal paste problem. Are you sure you reapplied thermal paste when installing the new processor? Even the TX3 can stop the CPU from overheating during startup while it boots. Yes, it could get hot if you let a lot of heavy work run on it, but at the start up, that's not such an issue.
Your computer's fan settings can show a special chart on the board. If you turn the fans off when the computer starts, you could see strange things happen. Try turning the speed up to 500 or higher before it starts working again.
