All of which are 100uF, 10V. Are they enough of a failure risk to warrant replacement? If so, what should i get as replacements for them? They're 5 or 6 mm in diameter, and 7 or 8 mm tall at the most.

Re: 13 Teapos on my Mainboard
Those are pretty small caps. I would say given their size, there's a low risk of failure. That said, the risk is there.
From the ones I can see in the photo, they are Teapo SS 10v 100uF.
According to the datasheet, that value of cap comes in two sizes: 5x7mm and 6x7mm.
The 5x7mm has 85 mA ripple, and the 6x7 has 100 mA ripple. You want a replacement that has at least that much ripple handling ability.
Something in Nichicon VZ or Chemicon KMG should get the job done.
This only applies to the caps I can see in the photos, which are the SS series. If there are other caps I can't see from other series, their values may be different.
Also...I see a GSC capacitor in the one photo. GSC capacitors are bad news, I'd take a close look at that one as well.
I see lots of Rubycons on the board, those are good. However, I can't make out what the tall VRM caps near the CPU socket are. Take a close look at those, as they tend to be the most stressed capacitors on the board.

Re: 13 Teapos on my Mainboard
I agree except for KMG and VZ.
Those aren't low ESR and better caps that small don't cost much if anything more.
While any cap -can- fail the 4 & 5 mm caps rarely do and that includes Teapo.
Any 4 & 5 mm caps rated for 85C instead of 105C are more of a concern than small caps of a particular brand name because they tend to start going bad after a few years.
[Except maybe for GSC or OST. Even in small ones I don't trust them around the chipset or RAM. IMHO those are best used for contaminating landfills. - That said, if they are -clearly- not caps that 'work' hard I'll let them ride if there are no other small caps that need replaced. The GCS I can see on your board is in the fan controller for that nearby header. GA likes to slide GSCs in that spot and as they don't 'work' very hard I wouldn't worry about it unless the fan is getting screwy.]
So, unless they are 85C or the board is flaky for no good reason [with otherwise good caps] I don't usually replace them. Sometimes I get a wild hair and do a 100% recap just because it's on the bench anyway.
I handle 6mm this way. [Revision 57 of Bonez's SOP.]
If it's 220uF or more I treat it as I do 8mm and up caps.
If it's less than 220uF I treat it as I do the small caps.

Re: 13 Teapos on my Mainboard
'k. There's four caps that are all 5 mm diameter 22uF 25V Supacons. I've heard that this brand should be replaced no matter how tiny they are. TopCat's got a 22uF 25V Samxon in his inventory. Is it worth spending the cash to get those replaced when I send the mobo to Topcat?

Re: 13 Teapos on my Mainboard
Never heard of Supacon. Maybe you mean Su'scon? Those are so-so, if they are in non-critical areas they will survive.Originally posted by PeteS in CARemember that by the time consequences of a short-sighted decision are experienced, the idiot who made the bad decision may have already been promoted or moved on to a better job at another company.
