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.
