The box contains exactly one fan and no extra brackets, cables or software. The supplier asks purchasers to compare the product photos with the old part and to confirm the model number before ordering. Each unit is tested before it ships.

Questions about this item

Will the BA31-00135A fan need any lubrication or bearing service over time?

The replacement fan is a sealed unit tested before shipping; no user lubrication or bearing service is required during its service life.

What thermal limit stops the Samsung NP780Z5E from running the fan at full speed continuously?

The laptop's own thermal controller regulates the fan speed; the replacement fan simply follows that signal and has no independent throttle point.

How much noise and heat does the BA31-00135A add when the NP780Z5E runs all day?

The fan matches the original BA31-00135A specifications, so acoustic and thermal output remain identical to the factory cooling profile.
