Questions about this item

How often will the internal fan need cleaning or replacement?

The fan is a sealed bearing unit rated for continuous operation; expect to clean dust from the intake every six to twelve months and replace the fan only if noise or vibration appears after several years.

What component hits its limit first during continuous full-load operation?

The 12 V rail is rated for 300 W; sustained loads at that level will cause the over-temperature protection to trip before any other circuit reaches its threshold.
