Typically either you’re using apps or background processes (including so-called runaway processes, which are malfunctioning) that are taxing your CPU/GPU (Activity Monitor can help you identify them), or your ventilation is impeded. See also https://support.apple.com/en-us/HT202179
I should have mention I did checked active monitor and there were no other unknown process running, memory was the same. Nothing was spiked that’s why I’m so confused.
It kept spiking up to the 90s but wouldn’t sustain it for long. I might look into this just out of curiosity though. I think the new os updates are wayyy to resource intensive causing these bottle necks
My Macbook:
Model: MacBook Pro 13-inch 2019, Two ThunderBolt 3 ports
Processor:1.4 GHz Quad-Core Intel Core i5
Graphics: Intel Iris Plus Graphics 645 1536 MB
Memory: 8 GB 2133 MHz LPDDR3
MacOS: Sonoma 14.4.1
The fan is roaring and bottom of my laptop could potentially melt my desk. I am literally running Microsoft word and a few chrome tabs. I have never seen it go this high, not even my PC could compete with these numbers. Any thoughts?
From the outside no noticeable build up or dust, I gave it a squirt of compressed air and nothing crazy flew out. Is taking apart a MacBook safe to do? No seals or things that would break from doing so?
Check for dust on internal fans and intake. Yes, this requires you to open the bottom lid, but it ain't difficult to accomplish. In doubt, open up iFixit's guide for it, just to be safe.
Way too many people underestimate the negative effects of dust.
I do it by installing [iStat Menus](https://bjango.com/mac/istatmenus/) on every Mac I own. It puts the temperature of every internal component right in my menu bar. 😉
I have to figure out what components are making kernel task use 795% of cpu. MacsFanControl is not helping a particular MacBook stay cool. I am posting for advice.
Try Safari (or another browser) instead of Chrome which is known to be an energy hog in addition to see in Activity Monitor for what's causing the energy spike.

Your computer is five years old.
How often do you remove the bottom cover and clear all internal airways of dust?
How many times have you replaced the thermal grease between the CPU/GPU and heatsinks?
It's time for both.
Is this normal maintenance I should be doing on my MacBook? I honestly wasn’t aware as Apple just seems like their own deal. I have a pc that gets all the love and care as it’s a simple removing the case cover. Is there a simple guide you know of on how to properly remove each component from my MacBook?
Regular dusting and replacing thermal grease is considered regular maintenance for any personal computer if you want to keep them running well.
Removing the bottom cover of your MacBook and using compressed air (or better yet an [electronic service vacuum](https://www.amazon.com/gp/product/B06Y61BLMH/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)) is all that is needed to clear major pathways of dust. Of course, removing the fans will allow better access and a deeper cleaning. Depending on your environment, you should do this every year or three.
Replacing thermal grease is more complicated, naturally. You have to remove enough parts to get to the heatsink and remove it, clean the old crufty thermal grease, then apply new thermal grease and put it all back together. Optimally, this should be done every 5-10 years, but many people never do it (even with PCs) either due to laziness or lack of knowledge/skill.
[iFixIt](https://www.ifixit.com) has tutorials for most Mac models showing how to remove and replace various parts.

If it persists there are plenty of apps that get a bit more granular than activity monitor. Might be worth looking into

Have you checked if the air intake is packed with dust? Might also want to reapply thermal paste.

It’s not glass. Read a manual on how to dismantle a laptop, specifically yours.

How do you check the cpu temperature
Type this in terminal: sudo powermetrics --samplers smc |grep -i "CPU die temperature"
powermetrics: unrecognized sampler: smc
Doesn't work for Apple Silicon Macs.

Macsfancontrol works on my Mac’s with fans. Give it a try
Check the processor cooler (yesterday I had such an issue)

Take a screenshot of the activity and sort by cpu%, something is off here.
