Replacement Fan for MSI E33

This new DBTLAP cooling fan is a direct replacement for the MSI E33 laptop series. It carries part number F730-CW and reference DFS531405MC0T. The unit is designed for owners who need to restore original airflow after a bearing failure or blade damage. Buyers who want a universal cooler or a larger external pad will not find that here.

Fits Inside the Existing Chassis

The fan operates on the laptop's 5 V rail and draws 0.5 A from the motherboard header. No external power brick or USB cable is required because it reuses the original connector and mounting points. Installation only needs a compatible screw pattern and clearance inside the E33 housing. Builders who need a second card or additional case fans cannot use this part.

Tested for Continuous Operation

Each unit is bench tested before shipping to verify spin-up and steady current draw at the rated 5 V 0.5 A. The design targets the thermal profile of the E33 platform during sustained workloads rather than short bursts. Users seeking higher static pressure or variable speed curves beyond the stock specification will not get them from this replacement.

Questions about this item

How long can the 5 V 0.5 A fan run before the laptop USB port throttles it?

The fan draws 0.5 A at 5 V, matching a standard USB 2.0 port rating, so it can run continuously as long as the port maintains that supply.

Does the fan stay quiet and cool when left on all day?

Each unit is tested before shipping to confirm normal acoustic and thermal behaviour at its rated 5 V 0.5 A input.

Which MSI laptop models is the DFS531405MC0T fan confirmed to fit?

It is built for the MSI E33 and F730-CW series; compare the part number E33-0900181-F05 and the photos with your original fan before ordering.
