Tiny Choyos & a couple GSCs on a Gigabyte GA-7N400 Pro

[StevieC]

The Choyos are 100uF at 10V, and measures 5 mm in diameter by 8 mm tall.
the GSC is either 2.2 uF or 22 uF at either 2.5 V or 25 V and measures 5 mm in diameter by 8 mm tall. a 2nd GSC is marked as 100 uF at 16V or 1.6V and measures 5 mm across by 11 mm tall Neither the Choyos nor the GSCs have any vents and there's one each of the 2 GSC sizes, and 11 of the Choyos (all the Choyos are identical as far as I can tell)

Are they small enough to leave well-enough alone or should I replace them?

MOST of the time you can leave those alone.
They do fail but not very often.
If the larger caps are good and board is acting weird and you can't find another reason then try replacing those too.

ok. I've identified the relevant caps. I'm doing the whole thing as a preventive measure, as the larger caps are mostly Nichicon HM(M)s which are known for being iffy so I'm going to replace them. One cap is so close to the CPU socket that the CPU heatsink fouls it. Is it safe to install the replacement with more length on the leads to orient it to lie parallel to the mobo?

HM with date codes 2001-2004 should be considered bad.
2005 and up are okay unless heat kills them. [Like in Dell/HP toaster ovens.]
Same-same w/Nichicon HN.

StevieC; You could poly mod it around the CPU socket if you are having problem with the capacitors height
Laying it down works too, but it is not very good because it increases the ESR... (short leads are important...)

Alas, there are no polymer caps of the appropriate voltage and capacitance for that particular position so the only option I'm left with is longer leads, or angling it outwards slightly to minimize the increase in lead length.
