I finally got all my computer parts, onlyproblem is, the water isnt flowing. My setup is like this, dd4 pump on the bottom, the top barb connects to my reservoir, the reservoir to my radiator, the radiator to my tdx block, then the block back to the pump. This is what happens, the pump works, and you can hear itsuckign air, then the water flows. from the pump tot he resrevoir theres water, then from the radiator to the otherside of the pump theres no water. when i turn off the pump, all the tubs are filled again.
