question about installing a cap rated for a lower temp

[kq702]

Hi I have a motherboard which is untested however I can see it has one visibly bad cap. It is 6.3 V, 3300 uF, and the temp is rated at 105 C.

I have a spare cap laying arround that is the exact same physical size, and has mostly the same specs. The only difference is the spare one is only rated at a temp of 85 C, not 105.

I understand that installing this one is not a good long term solution, however if I install it will it work for even a small amount of time? I just want to test the motherboard. If I install it and the motherboard works I will remove it and order the cap that is rated for a higher temp. So can I use this one for now as a test? Or would I risk further damage by installing it?

yes it should work! in the area that the one cap was blown, the others of same value could be bad as well. would suggest a reacap of all of them if ya keepen board for the long run!

Re: question about installing a cap rated for a lower temp

On a motherboard, 6.3V 3300uF capacitors are almost definitely a very low ESR capacitor. 85 degree rated capacitors are almost definitely not low ESR. I wouldn't expect it to work for very long, if at all with that replacement.
