Questions about this item

How often will the fan need cleaning or replacement under normal use?

The unit is tested working and rated 400W; fan lifespan depends on dust levels and load, so plan periodic cleaning rather than a fixed interval.

What component reaches its limit first during sustained full-load operation?

The 400W rated output is the primary limit; sustained loads at or near that level will stress the internal components before any single connector becomes a bottleneck.
