Well that really doesn't sound good so if I were you I would not try to boot until you are sure you have good contact between cooling and CPU. Or at least only boot for a very short time....
Can you feel the tubes of the cooler are they warm or one of them warm next to the pump block? If either tube is warm then the pump is not working.
I presume you have set the cooler up properly....power to pump fans to pump block and connection to CPU FAN header on Mobo?
Make sure you have the power connectors fully populated
lastly the RAM....I presume you list that RAM as kits you have tried? You can not of course run those kits together. Are they single dual channel kits?
You could also try updating your BIOS..
