Questions about this item

Will the Dell K5146 system board need a capacitor replacement later?

The board uses standard electrolytic capacitors near the CPU socket; plan to inspect them after several years of continuous operation and replace any that show bulging or leakage.

What thermal limit appears first when the OptiPlex GX280 runs a sustained load on this board?

The Pentium 4 processor hits its thermal throttle point before the board VRM or chipset, so the CPU clock will drop first under prolonged heavy work.
