Corsair H150i PRO aio

I have the h150i aio hooked up to sata and three fans hooked up to the aio splitter it came with. I have the 3pin connector to the cpu-fan header and tried it with the aio_pump header and got the same error. The corsair block lights up but the fans don't run and I get that error when i boot it. Anything else I can do it try differently?
 
Solution
Certainly could be. It's not powering the fans via the block, which it should.

Provided you have the fans secured to the splitter, are adequately powering the pump (via SATA) and have seated the cooler correctly, chances are pretty good the issue lies with the AIO/block itself.

Assuming this is new, I'd suggest a return to the retailer or RMA to the manufacturer.

Hopefully I'm missing something obvious, and someone else will correct me but, if the fans are working off of the header directly but not via the splitter, there's a problem.

You could just run the fans from the CPU_Fan, CPU_Opt etc, but if there's an underlying manufacturing defect, it's best to get that addressed/replaced.

The fans are connected to the splitter on the pump?

If the fans are connected to the pump, and the pump is receiving power (from SATA), then they should certainly be spinning.

The CPU_Fan error is typically because nothing is detected. Are you sure you're connected to "CPU_Fan" and not "CPU_Opt"?

Yes they're connected and yes it was in CPU_Fan header, I tried to put it in aio header and got the same error message

If you connect the fans, or even A fan to the CPU_Fan header directly, does it spin up?
If not, then the problem likely sits with the header (try each fan to rule out a defect, of course).

If they do spin up in that situation, then you may have a defective AIO.

When I put a regular fan into the CPU_Header it spins on boot which mean it could be a faulty aio?

Alright I'll most likely return it and get a new one
