Hi, Your computer has been producing a crack sound during startup and while running. It seems to happen frequently, around every ten minutes. After checking, it isn't the fans or cooler units. My suspicion points to the PSU fan or one of the GPU fans. Here are the details: specs listed below. I also shared a video of the noise from under the case: Corsair 7000D airflow 4 140 fans, brand new CPU, Intel Core i7-9700K, Corsair H100i RGB MB, ROG STRIX 1080, 32GB RAM, Corsair Vengeance PSU, Cooler Master Masterwatt 750 Bronze. Thanks for your assistance. Video.mov

Only check the fans by gripping the hub to stop them from rotating on the GPU

I just tried it again and the same issue persists. I believe the PSU or one of the hard drives might be the cause, though I doubt a drive could produce that noise. The sound appears to originate from the rear of the PC.

Check if water pumps generate sound. Remove the HDD and start from an SSD. Is there another power supply available for replacement?

The noise might originate from a spark inside the PSU, possibly involving a capacitor that charges, then shorts, and subsequently recharges, repeating this cycle over a certain period.

I just checked the boot from the SSD, but it didn’t change. Unfortunately, I don’t have another power supply to try.
