Fans & Ram Question

Hi All,

just recently got my new PC from PCS - super happy! just a couple of questions which i dont know the answer to. (Spec below)

1. I purchased 2993mhz 2x4gb RAM - but i can see the PC is running at 2666mhz - is this correct? or should it be 2933 - can i just go into the bios and change this to 2933 and that will be fine?

2.I have some additional fans from a old rig (blue led like i bought! great stuff!) they run fine off the 4pin Molex connected to the PSU (albeit at 100%), but when i put them through 3 pin onto the motherboard i have two issues.

1. they dont light up? - and run at slow speeds.
2. they dont appear in the Smart Fan 5 settings in the Bios

any idea what would be causing this? do i need to install them or something?

Edit: Forgot to add my spec

Where does it say that it's only running at the lower speed?

What model of fan are they exactly?
