If you do a good amount of research, you'll quickly learn that these all-in-one coolers are actually under-performing for what you're paying for. I was first sold towards the H50 when I saw videos of the easy installs and the no-maintenance setup. After I had it in my rig - 20 mins went by until I wanted to slap myself with it
Fast forward a few years and I planned out my first official (custom) watercooling loop by reading through anything that was a watercooling sticky(surprisingly the sticky here is well stocked with info - good work Rubix). Did more research of the parts I wanted and needed for my setup and finally pulled the trigger---> courtesy AMS rig(in my sig if you'd like to know more).
I needed information to proceed on my long road ahead thus the knowledge I spoke of.
The parts I bought in my custom loop were also through alot of research and the sort of temps I'm seeing on my overclock came from that information thus the dividends.
Now,
The H80 is a single 120 rad in a thicker format than an H50 but if you've read the watercooling sticky - you'll understand that a single 120 rad isn't the road you'd want to drive on for ~$100 couple that with the fact that the pump is weak and isn't really good for any additional blocks or radiator space.
If you tossed a coin to a beggar, you usually see two sides to that coin tossed - thus
"the other side of the coin" reference
* sorry this thread has moved from a CLC issue to a thread about custom watercooling cooling to philosophy...sorry mate
