Lenovo IdeaCentre A740 A540 CPU Fan

This replacement CPU cooling fan fits Lenovo IdeaCentre A740 and A540 all-in-one systems. It operates at 5 volts with a 2.25 watt power draw. The part matches the original 90205305 and EG90120S1-C010-S99 specifications. Buyers needing a fan for a different Lenovo model or a standard desktop motherboard cannot use this unit.

Direct OEM replacement restores original cooling

Installing this exact-match fan restores the factory airflow and acoustic profile without adapter cables or firmware changes. The 5 V connector plugs straight into the existing header. No mounting hardware or thermal compound is included so installers must reuse the original screws and paste.

Questions about this item

Will I need to replace the EG90120S1-C010-S99 fan if the bearing wears out?

Yes, the fan is a single field-replaceable unit; when the bearing or motor degrades you swap the whole cooler using part number 90205305.

What limit appears first during sustained loads on the A740 or A540?

The 2.25 W power budget caps airflow, so thermal headroom runs out before the 5 V supply becomes a constraint.
