Mac Mini 2010 - an element on the motherboard has broken off?

Question

Mac Mini

Good afternoon,
I damaged the macmini motherboard when I changed the hard drive. Macmini works, but the cooler spins at maximum speed and buzzes like a vacuum cleaner. I wore it to the service center, they said that in order to fix it, I need the characteristics of the element (which I tore off) or another macmini to measure them.
I am in Kyiv. Suddenly, someone can help with this question in one of the following ways:
1. Suggest what kind of element it is (capacitor or inductance + characteristics)
2. Rent a Mcmini for 1 day
3. Recommend a service center
Thank you!
Update: Tried to find on apple.com how to ask them the same question, found only Express Lane. Maybe someone has already contacted support with a similar problem and knows the support mail.

Answer 1

In general, in the norms of ss they do not ask for another poppy mini to take measurements.
Contact the SC with good reviews.

Answer 2

You can find the inductance with a multimeter. Directly on the board, of course, it will indirectly measure this, but still, they should have low resistance.
If the capacitor is higher above the element, then it is exactly the inductance that is torn off.
And I would pick up the inductance by typing. In the smd case, they have a small run-up.

Answer 3

A lot of time has passed, I assume that the person who asked the question no longer needs an answer =).
But it will be useful to those who accidentally stumble upon this post, such as me.
I ran into a problem exactly as the author writes. Managed to solve the problem.
C6500 is a capacitor (pale yellow in the diagram), I had it partially torn off (shifted at the moment the cooler contact was removed from the board), soldered all the legs in place.
The missing element - L6500 - is a kind of inductance element, I did not find a replacement for it, I just soldered a jumper (closed the contact).
After these actions, the system calmed down for a short time (1-2 seconds), but then twisted again at full 5500 rpm.
I found a cooler speed control software - it also shows temperature sensors.

Important: if one of the sensors is broken/disabled, the system will also rotate the cooler to full.
In my case, all temperature sensors were in place. The problem was in the cooler speed sensor, it was spinning at 5500, and 0 RPM was shown in the system. The speed control software could not change the speed of the cooler.
Additionally , the wire on the cooler itself was damaged (visually not noticeable). To be more precise - one wire that is responsible for the speed sensor. I shortened the cooler wires, soldered the connector contact and everything worked.
For information, the assignment of contacts (from left to right in the photo):
- (ground)
+ 5V (cooler speed control - pwm / PWM digital signal)
+? V (current cooler speed sensor)
+12V (power supply, always 12V, because speed control via pwm signal)

>Macmini works, but the cooler spins at maximum speed and buzzes like a vacuum cleaner.
But what if you go the other way and hang a variable resistor on the fan to limit the speed. well, at best, bring it outside to control the speed. Of course, provided that the matter is in high speeds and nothing more.
Of course, I understand that I look like a pagan in church :) I apologize in advance to all Yabloko people.

Answer 5

Maybe somehow you can use the markings on the motherboard?
If C6500 refers to a torn part, then we can assume that this is a container.

Answer 6

Go to a Mac reseller and ask them to look at the Mac mini board.

Answer 7

Can you clarify the model?

Answer 8

In normal SCs, there are board drawings on which each element is signed.
Look at the name of your board and try to find its scheme on the Internet, it's Chinese :)
