I don't really know what cooler it is. How would I find out? Also, I want a closed loop to free up space because it looks nicer and I can't fit more RAM and side panel fans with the cooler.
What case do you have?
What motherboard, cpu and ram do you have?
A liquid cooler is expensive, noisy, and less reliable. It's only purpose is to extract the last couple of multipliers out of a highly overclocked cpu.
