I was seeing high core voltage and core VID so I uninstalled the Intel Maximizer application and will do my overclock manually. That however isn't the problem--the issue is that the coolant temperature doesn't rise as much as it should. Setting the voltage issue aside, I will re-seat the CPU and see if that impacts the coolant temperatures. Thanks again for your help. At least I will get the voltages under control!

Are the temperatures you referenced the amount of rise from idle?

I will follow up and get back to you tomorrow. Thanks so much for your input.

Yes, this question is regarding the system in my specs. The idle temps for the CPU and coolant stay relatively constant when at idle so the idle fan speeds seem sufficient to maintain acceptable idle temps for the CPU at approx. 40C. The Package Temperature fluctuates briefly to as high as 50C when on idle due to background system activity. Ambient air is controlled at approx. 73F. The voltages to the CPU are being controlled by the Intel Performance Maximizer application which throttles power to the CPU to achieve maximum processor frequency within power limits set by Intel for the specific CPU it is controlling. So, if I am reading your reply correctly, the coolant temps not rising much when the CPU temps are hitting max could be due to a contact issue between the pump and the CPU. And you believe this behavior would not be due to a faulty coolant temp. sensor. After your reply with this additional information and waiting for other replies, it may indeed be time to re-seat the pump to the CPU.

I have the radiator on the front of the case with the supplied fans pulling and another set of fans pushing. The problem I'm seeing is that the coolant temps showing in iCue start around 28.6C at idle and top out at 29.8 when running a stress test using Intel Extreme Tuning Utility. The CPU temps top out at around 85C when VCore starts throttling to prevent higher CPU temps. As a result, the Corsair fans and the unit's pump never ramp up even when on extreme settings. I have made a custom fan curve that goes to 100% when coolant temps hit 28.8C. But the pump is always at approx. 2,695 RPM when on the extreme setting and of course, I can't define a custom curve for the pump. This simply doesn't seem right. The coolant temps should be rising much more than they are when the CPU temps are at max. of approx. 85C. I used the correct standoffs and screws when installing the pump as well as the supplied thermal compound. The pump seems firmly seated on the CPU. The top of the radiator is about 2" higher than the pump. There are no sounds coming from the pump. Could this be a defective temp sensor in the pump? What else can I do to find and hopefully fix the cause of this behavior?
