Problem with CPU temperature after installing SSD?

Question

macOS

Good day, dear ones.
I fell for a lot of articles promising a significant increase in speed when installing Mac OS X on an SSD.
I put the whole thing through a pre-purchased optibey, SSD chose Vertex 4 128GB.
And so, we have:

HDD in optibe, SSD instead.
Also, TRIM enabled, noatime disabled, hibernation file moved to HDD.
A custom directory is also mounted on the HDD.
Spotlight is off (I just don't use it) I'll
try to describe the problem.
Often, during the day, without running applications, the system starts to actively do something, which I cannot notice in the task manager. Everything is normal there, the processor works at 3-4%, but at the same time its temperature is about 70C, and the cooler rotates around 4000 rpm.
During the day or at other times of the day, the temperature of the processor varies from 40C to 55C.
For example, now, only Google Chrome is running with one active tab, the temperature looks like this:

From what, exactly in the evenings, this jamb occurs, I have no idea.
I searched all related topics, but did not learn anything intelligible for myself.
I ask for your advice.
Sincerely.

Answer 1

Did almost the same thing yesterday. Macbook Pro of the same configuration. I'm a noob, I just was able to put the SSD in optibey and copy the profile to it. Very satisfied. From practically inoperable, the beech began to simply fly.
Please tell me how to do this:

Also, TRIM enabled, noatime disabled, hibernation file moved to HDD.

Answer 2

I see the main mistake that the SSD should be in optibe, and the HDD should be in its place.

Answer 3

In terms of cooling and data protection systems, and from a series that if a laptop falls, the disk is urgently parked to avoid damage. All this will not work in opticbey

Answer 4

cat /var/log/daily.out- everything is written here.
