ML120R, not cooling CPU. CPU Temps 115 C ASRock Z390 Pro 4 Mobo Random shutdown

CPU temps report 115c and won't go down.

Current new build specs:

Mobo: ASRock Z390 Pro4 (Lastest BIOS V4- Reporting Temps 30c)

CPU: I7-9700k (Reporting Temps 115c)

GPU: Asus ROG Strix 8GB (Reporting Temps 30c)

RAM: 32GB Corsair Vengence 3000mhz (Reporting Temps 30c)

Case: Deepcool Mattrex 55 w/ 3 front intake fans for cold air (2000-3000 RPM)

Exhaust Fan: Cool Master 120 ARGB fan (2000-3000 RPM

CPU Cooler: Cool Master ML120R Dual Fan w/ Radiator and Water Cooler (Used on top of the case as exhaust heat 2000-3000 RPM)

SSD: Intel 1tb M.2

Storage: 4tb Seahawk SATA SSD

All fans appear to spin and are configurable besides the water pump fan that reports no RPMS

I am building this new and I have never been able to get the CPU to go below 115c. I have followed the directions fully.

1. I have confirmed that the bracket is properly configured for my socket type.

2. Confirmed to add thermal paste and remove the cooler plastic cover as instructed

3. Connected the 4 pins from the water pump to the 4pin CPU Fan connector labeled on the motherboard.

4. Originally connected the 3 min water pump connector to PMW_Cnfg1 3 pin connect labeled on the motherboard

5. Within BIOS and ASroch tune utility, I have set for Fan Auto detection based off CPU temps 

CPU temps continue to climb up to 115c

The second configuration was to

1. Take the 3 pin water pump connector and move it to the closest 4 pin Chassis fan connector that was labeled Cha_Fan2/ WP

2. Configure Cha_Fan2/WP to WP mode and PMW mode with fans set to max

CPU temps continue to climb up to 115c

My fear is that the everything will tend to burn out and short out if the CPU issue is not addressed any my 2k investment will be voided if not addressed. Please assist as it would be greatly appreciated.

All the best!
