Alright, one last follow-up question. I hooked up the pump to one of the fan headers (JPPWR) to see what it is registering for RPM. E-LEET showed the pump operating at 4250-4350 rpm, which sounds about right. Could the pump be compromised in another way? Maybe some sort of pressure issue, where even though it's spinning at the correct speed it's not pushing the coolant well?
Is there a better pump than the swiftech MCP655?
My setup includes:
MB/chipset waterblock
CPU waterblock
Dual GPU waterblocks
120mm Triple Radiator
XSPC Dual Bay resevoir
