Hi there.

Its me again.

Have here one 775 motherboard and have changed some electrolytic capacitors, but for one i didnt have the same and put higher voltage. Now its higher and cooling cannot be installed.

Of course i attach photos. How to proceed? Do you think i will be able to find 680uf 4v in this size in my countrys(eastern europe) local stores or the value is very untypical? Maybe the biggest store here has only 16,25 and 35V(fujicon) variant and i think they also will be very higher.

Can't say, as we don't know which country you're in and you haven't told us the size .
Can you get the correct cap by mail order?

When I was looking for replacement caps, I found this advice:
"For replacements:
- ESR should be the same or lower.
- Ripple should be the same or higher.
- Voltage should be the same or higher. [Without getting ridiculous.]
- Don't wanna change uF unless you have to.
- Also make sure it will physically fit both diameter and height."

I once had a motherboard that was out of warranty due to age. I called the manufacturer for some parts.

The manufacturer preferred that they did the repair. They offered to repair the board and ship it to me free, if I would ship it to them.

Always check with the manufacturer.

I have received many free parts.

capacitors do work installed sideways (bent over to allow for the heatsink)
