A power electronics cooling assembly (500), the assembly comprising: a housing (502) for the power electronics that is mountable to a bulkhead (470), for separating a fire zone from a non-fire zone of a gas turbine engine. In the non-fire zone; one or more ducts (504) for extending from the bulkhead (470) to the housing (502); a fluid supply (506) and return pipes (508) for extending through the one or more ducts (504) from the bulkhead (470) to the housing (502), wherein the fluid supply (506) and return pipes (508) are for carrying an ignitable fluid coolant; and a heat exchange structure (510) arranged within the housing (502), wherein the heat exchange structure is configured to receive the ignitable fluid coolant/fuel from the fluid supply pipe (506), facilitate transfer of heat from the power electronics within the housing to the ignitable fluid/fuel coolant, and output the ignitable fluid coolant to the fluid return pipe (508). A system, gas turbine engine assembly and an aircraft comprising the power electronics cooling assembly are also provided. The assembly may mount on anti-vibration mounts (503).
