Default Suitable capacitor to replace two of these in network switch

Hi All,

I've just opened up a network switch (HP procurve 2510-24g) as the fans were so loud, and when looking over the board it looks like two of the capacitors have got some issues, see pics.

As best I can tell, these are KZG 10V 1500uf in a 10x16 form, so a impedence of 0.019 and ripple of 2000. From some old threads I found, these are well out of production now and there's been questions about replacements in the past. I've got some panasonic 1500uf 10v, ripple current at 1790 but impedence at 0.028. Is that likely to be a bit too high? Otherwise I found available rubycon 1500uf at 16v, that looks pretty close with 1960 ripple and 0.02 impedence, should I go with them?

No faults/error lights when it powers up so I guess the existing caps are just about OK but I'd like to do something for long term stability.

Thanks for any suggestions!
