My new PC is making a loud buzzing noise coming from the CPU area inside the board behind it.
Hi, my name is Omar. One month after I bought a new computer and started playing games, I heard a zzz sound coming from the back of the computer. The place where it came from was so nice that they helped me change my graphics card (RTX 4070 12gb) to an RTX 4070 Ti Super. After this change, the problem got worse. They also changed my motherboard from Asus B760 to Asus Z790 Plus and replaced the power supply cable with a new one labeled "Asus Gold." Now I don't know what's wrong. I tried testing everything in my BIOS settings, but nothing helped. Even after changing CPU settings, it still didn't work. My CPU is an Intel Core i5 14600K. I have paid for all this stuff already and the problem keeps happening. It isn't coil whine because I tested every part and the sound happens right away when starting a game or going into menus, even if I turn off the fans. The zzz sound is coming from behind the motherboard near where the CPU sits, on that metal grey part with the cooling fins. I checked all my fans to make sure they aren't causing it, but turning them up made the noise stop completely. Please help me solve this issue because it's been so long and I don't want to pay for more parts.

Welcome to our forums! If you are posting about fixing or troubleshooting something, make sure to write down all the parts of your computer. You can list them like this: CPU: Cooler: Motherboard: RAM: Hard Drive/SSD: Graphics Card: Power Supply: Case: Operating System: Monitor: Also tell us how old your power supply is, not just the brand or model number. Please also let us know which version of your BIOS is installed right now on that motherboard. Since you changed parts, we will need two sets of information: one from before the change and one after it. Did you restart your computer with a new operating system after swapping the board? No, it's not coil whine because that noise happens every time I change anything else in my rig. If the sound isn't there even at the shop where you bought the parts, then what is different might just be that your power outlet doesn't have enough grounding. Another thing you can try is to make a roll of paper and hold one end up to your ear while moving your other hand around to find where the noise comes from. Just remember, this thread moved over to the Systems section!
I have fixed my computer settings because you asked. The sound comes from the motherboard, the CPU, or both. The seller shop had better quality audio than the computer, but it is still lower than what you get there. I did not reinstall my operating system, but I updated everything and this install is not old like the one on your machine. I installed it using a drive that was from an earlier PC, but I used a different SSD for this new setup because the original download was made three months ago.
Hi, Im Omar. One month ago, I got my new computer and started playing games right away. Suddenly, there was a loud zzz sound coming from the back of the motherboard near the CPU area (the metal part that is grey). The seller was very nice and helped me change my graphics card (rtx 4070 ti super) instead of just buying it new. Then, they also swapped out my motherboard from an Asus b760 model to a better Asus z790 plus model, and replaced my power supply cable with a new Asus Gold one. Even after all these changes, the problem is still here. I am really confused about what to do next. After testing everything in my BIOS settings, nothing fixed it. Maybe the CPU or the cooler are the issue? Or something else? Anyway, this computer has paid for me so much money and now I can't use it because of sound problems when playing games. Please help me fix this since I bought a new PC without knowing what to expect.
Based on what you said, your PC works well. The only issue is a small noise you might hear. It depends on what makes the sound, but if fans spin fast, they can hide the noise or make the case shake instead of making it louder. This backplate stops vibration from going through to your CPU socket. Sometimes the part isn't held tight enough so it rattles when things move, and sometimes your cooling fan is actually the source of the noise because it's directly over the processor. All noises coming from that area are usually caused by the pump in the AIO cooler. Those come from the bearings in the pump, trapped air inside the motor, or rarely, metal parts vibrating against each other. So, check how your backplate is attached to the case. You'll need to take it off to fix this. The backplate guide shows where to look in step one under letter B.
I have tried to make the fan spin faster on my cooler, turned up the pump flow in the BIOS, but still no clicking or whirring.
If you adjust how fast your fan or pump spins and the weird noise stops, then it was probably just a loose part rubbing against itself. Some fans and pumps make those annoying grinding sounds at specific speeds, but running them at other speeds makes that problem go away. If that happens, it means the bearing is working fine. The best way to fix this is usually just changing out the part you had to begin with.
When testing graphics on the CPU, you won't hear anything except when you are actually playing games.
