Questions about this item

Will the heatsink fins on this NDLIULEI cooler need cleaning or thermal-paste replacement later?

Yes, dust builds up on the heatsink fins over time and the thermal paste between CPU and cooler degrades, so periodic cleaning and re-pasting keep temperatures stable.

Under sustained load, does the fan speed ceiling or the heatsink thermal capacity limit cooling first?

The heatsink’s thermal capacity is reached before the fan hits its maximum speed, so the fin stack saturates and becomes the bottleneck during prolonged heavy workloads.
