Windows 10: LAPTOP MAKING HISSING NOISE WHEN HOT

My laptop gets very hot since it's a gaming laptop. Asus ROG Flow X13 2021 model. I am hearing a very weird hissing noise and my laptop gets extremely hot underneath. My vents are clear from dust since I do a monthly cleaning. The noise sounds like something sizzling. It's right between the fans, towards the top middle of my laptop. I'm not sure if it's the thermal paste or what. Never heard it before till now. Please tell me what I should do. I'm going to take it apart and see if I can find anything.

Nokia 6233 makes strange weird hissing noise

Has anyone had a strange problem with the 6233 sound going all screwy. After a while, the sound on my phone just seems to go crazy and whenever it should be making a noise (like ringing, keypad tones, etc) it just hisses. When I receive any calls, neither
the caller or me can hear each other, only the weird hissing noise is heard by both of us.

The phone also tends to reset by itself now and then.

I just got this phone last week and I have started getting these problems - and hence am very disappointed.

Any ideas/help appreciated!
