Well, my Gateway monitor seems to eat caps. So I was thinking there was some systemic issue going on here and what I'm thinking: the heatsink is blocking convection flow and thus roasts capacitors by radiation!
Now what I wonder. This piece of aluminum heatsink is obviously blocking convective flow. I could add a fan but there are some other issues involved here. How about...drilling holes into the aluminum?
The holes would add surface area and allow air to convectively flow through the heatsink which could reduce temperatures. However this would of course reduce the thermal mass of the heatsink which might cause other issues.
Some mechanical engineering/fluid dynamics at work here... hmm! But a design defect here methinks.
(And I'm out of 1000uF 25V low esr caps... sigh.)
