Does the small squares in the above picture need thermal pad (not covered by the 0.5/1mm markings)? Or is it ok to just leave them without any heatsink contact?

Thanks in advance.

The small black rectangles are surface mount capacitors and do not need additional cooling.

Why do they not need cooling?

Would it help with long term durability if it were cooled?

Capacitors generally generate next to no heat under normal conditions, they're passive components.
It wont harm to cool them, but tantalum capacitors like the ones in the picture don't really get anything major from it.

All they do is smooth out the output from the VRM.

Where did you get that picture from, cooling the inductors like that as well is unusual.

What's an inductor? The gray squares?

How about the 8-pin chips? Those are vrm and need cooling right?

Yes, that's an inductor. They don't really need to be cooled tbh, they are just copper wire coiled around an iron or ferrite core so even 100C+ wouldn't negatively impact their operation much. Of course they don't normally get nearly that hot.

Those "8-pin" chips are mosfets and cooling them is always better than not doing so. Basically, less heat equals better voltage regulation and less leakage and more heat makes it do the opposite. The same concept applies for all other electronic components as well.

The 8 pin mosfet is cooled properly. But I had to stack a thermal for one of them.

The 980M I have comes with thermal pad for the inductor, capacitor and the 8 pin mosfet. So I covered all of them.

So it's ok to not put heatsink on the inductor and capacitor?

Would it acually increase oc stability if they have thermal contact with heatsink?

Probably not. Probably wouldn't hurt either though.

Ok, so it's safe to not put heatsink on them.

But for safekeeping, put a heatsink if possible?
