I am assembling my first computer and using a Raidmax case which came with two case fans and the usual
internal PSU fan. With everything connected to the Motherboard and power switched on the motherboard
standby light comes on and and the Heatsink cooling fan starts to run, but the case fans are dead !! I disconnected the power cable to the board,then disconnected the case fans,and on checking with power on
their appears to be no power reaching these fan connectors !! Could this indicate a faulty PSU ? Can some kind person help please ?

I'm not sure that I understand you correctly, did you disconnect the 20/24 pin connector from the motherboard or the connectors for the fans. If you disconnected the PSU from the from the motherboard and are trying to read the voltages you will have to place a wire jumper form the green wire to any black wire to enable the PSU to power up when it is disconnected from the motherboard.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Thank you dc3, yes i did disconnect main motherboard power and try to read voltage from the fans power connectors!! would it do any harm to leave everything connected and heatsink fan running whilst testing chassis fans output voltage?
