Aspire E5-575G_115F_1.32 Processor buzzing noises

Just in the last two days or so I've been getting a loud buzzing/'digital' ticking noise from my processor, a i5-7200U running at 2.50GHz. As if the processor is working extra hard or has been over clocked in some manner. Using tools such as Speccy I've gotten no indication (that I as a layman) can say should be causing a problem. It's not running at a high idle temperature (only 45-55 C), CPU usage is normal. It's not the fan as it is coming directly from the position of the processor and I've never had an issue with the internal fan being loud, not to mention the two types of sound being different in nature to begin with. On Friday and Saturday I installed new Windows 10 updates, on Sunday when I booted up Dragon Age Inquisition to play I began to hear the noise despite not having this issue when playing it just the night before. It also is not just a CPU load issue as it is persistent. I only got it to stop once after turning my laptop off and attempted to diagnose my problem with opening the back panel, but due to a screw that wouldn't fully release from it's housing and the speaker cable not coming free it was a waste of time. Only after booting up afterwards did the noise not start up, and only started up after attempting to play the game again. Turning my laptop off and back on or restarting has not resolved this issue as a persistent problem. I don't know if this is something that is a sign of something wrong with the processor or nothing to be specifically worried about. So I don't know what to do.

That is not a CPU buzzing noise, CPU’s don’t make a noise, its more likely that it’s a fan noise, CPU’s don’t have moving parts lol open the Aspire E5-575G up again and clean the fan and its ducts, yes I know that you’ve had some problems but see the link below of how to do it properly.

Take the fan/heatsink out so that you can clean the fan and repaste the CPU/GPU (I suggest using the Thermal Grizzly Hydronaut thermal conductive paste and applying it with the ‘Pea Dot Method” on both and also clean all the components inside of your Aspire E5-575G with a soft hair brush and make sure that you are using an anti-static wrist band.

Also, it’s a very simple process to open your Aspire E5-575G (if done correctly?), see here of how to do it: https://laptopmedia.com/highlights/inside-acer-aspire-e-15-e5-575g-disassembly-internal-photos-and-upgrade-options/

Aspire E5-575G fan and CPU setup

The problem is, is that unless it's the fan causing vibrations further down toward the heat sink cover for the CPU, there's nothing to be making noise unless there's a fan under the copper cover for the CPU itself as it's literally coming from that spot, not from the main fan. Also CPU's don't have moving parts but can still produce noise due to the electrical current. Pull out all the fans on a computer and have the PC pulling nothing from the HDD and you'll still hear noise from an active computer. In either case, if you mean the primary exhaust fan, I can clean that fairly well without removing anything. At the least it's good to know it's not an imminent hardware threatening issue.
