Questions about this item

How often will the internal fan in the 0Jh994 need cleaning or replacement?

The 305 W unit uses a standard server-grade fan rated for continuous operation; under normal office conditions it typically runs for years without service, and replacement is only needed if bearing noise appears.

What limit appears first when the 305 W supply runs at full load for extended periods?

The 305 watt ceiling is the first constraint; sustained draw at that level will trigger the over-current protection before any thermal limit is reached.
