Video encoding noise

I've got a lot of MP4 files on my computer, and I want to convert them into MKV files. I have a program to do this, but when I start the encoding process, my fans (not sure whether it's the case fan or CPU cooler) starts spinning up and going crazy. My CPU temps also spike from 30-50C to 70-80C. Is there something that could be causing this? It's usually a quiet(ish) PC (or it was until I put a WD 8TB in it, but this noise far trumps that of the new drive).

 

EDIT: I'm very new to video encoding so I know nothing about what should be happening. Sorry if this was kind of a basic question.

Wait, why? Filename extension change doesn't always mean anything...

Yes, the video encoding. This is all normal and intended behavior.

I'm doing it because I've noticed a bunch of MP4 files are getting corrupted on my disk for no apparent reason and I saw a Techquickie video that I think said that MKV files don't corrupt or something.

no they're just talking about the ability to play it. That is, while mp4 could refuse to play at all, mkv will play up to the corrupted point which could be as little as a second or two.

 

They dont fix anything either

Oh, my bad. I must have misinterpreted it.

What you may be thinking about is with recording, if you record in the MP4 format and the recorder crashes, the file is corrupt. But if you record to .flv, it doesn't do this.

That's a thing in OBS, with recording.

 

So perhaps you heard that?

 

Anyways, doesn't sound like there is much use in encoding..

But to answer the original question; encoding is generally done on your CPU and it's a very intensive process that can fully utilize all threads of a CPU, make it Turbo to its highest all-core clock, etc. 

This will stress the CPU more, this higher temps and louder acoustics.
