Yeah its fairly wastefull unless you are using sub-800 RPM fans. Its too thick to really move the air all the way through at that speed and after a few days of 24/7 mining it starts to warm up at the top where the fittings are. its still basically room temp but slightly warmer. Putting a fan for push/pull for just that one space is enough to remove the heat. Its not hot, just warm. However maybe just a pull setup would solve that. Honestly my pump and PSU fan is the loudest part of my setup.
Here is a list (not in order) that would recommend for blocks.
EKWB (for monoblocks)
Here is a list of companies I think are either too new or just eh for the price currently.
I like to mix because for one you cant find all the parts on one website. Stuff like Monoblock only EKWB really makes. Bitspower has one or two, but not one for every board like EK has. I would not recommend Nickel plated stuff from EKWB right now, its hit or miss if the nickel will stay very long.
For radiators I would say only about three that are top teir and the rest are rated up and down per series.
#1 Hardware Labs (Everything is good but cost $$$$)
#2 Alphacool (Monsta Super thick)
#3 Aquacomputer (Only ones that are FULL visible copper)
For pumps they are prettty much all the same however some are PWM and others have higher operating temperature. One of my pumps is 65c and the other is 55c. Still if your loop is 55c at the reservoir than you have much bigger problems. Alphacool released a new D5 pump a few months ago that is 40% quieter at full speed. Besides that the base units are all the same.
