Case fans not spinning up (Yoyotech/NZXT built system)

[Solnyshko]

New build (or rather, system purchase - I didn't build it) and the two case fans are failing to fire up on start up.

Is this normal behaviour? Do some mobo/case combinations boot without spin up and kick in only when temps rise?

Seems odd to me. Also the case is advertised as having white case lighting which isn't coming on.

These are my specs:

Ah OK, good to know - though I feel I need to confirm it's only that, without tearing down the entire build to check connections if at all possible!

Any recommendations for thermally monitoring CPU/GPU/RAM etc from within the windows environment? Can't seem to find a way to do this natively in Win10 - maybe I need to install third party software...

Definately strange. Pushed the to CPU 55degrees and GPU to 82degrees trying a game - DayZ - and the case fans still won't kick in.

CPUID was a good call, thanks - temps decribed measured from that

Are they plugged in? Does the case have a button to select on and off? Is the power plugged into the case/fan power supply?

Right well, in answer to that, this doesn't look too good does it:

Here's a schematic of the board showing chassis fan connectors 1 and 2 -

And the view of the build showing the relevent top half of the mobo -

and details of each BARE connector terminal

Is it common practice to run the chassis fans directly off the PSU for the sake of cable tidyness? I suppose the next step is rip off the other side panel and see if the've been connected to a splitter running up the back hidden behind the mobo...

Did it not come with a user manual?

As has been mentioned, if it's not working properly try contacting the seller.

Well, I bought it 'as new' off fleebay from a private seller - not sure how much he'd be able to help. Strange though as the unit was packed and wrapped up in cellphane, factory fresh. Clearly never used before.

Resolved! Sort of... no fan controller just a simple splitter, the passthrough (combining the absent lighting) had not been attached to the 4-pin molex power source. It was hidden round the back of an otherwise very tidy build behind the motherboard plate.

Is it normal practise to run chassis fans directly off the PSU, rather than the dedicated mobo connectors?
