1. Yes, they "say" that ... monitor manufacturers say that their response times are half what they test at ... when fan manufacturers say 60 cfm and 1.2 SP, that means:
a) it will do 60 cfm at 0.0 SP
b) it will do 0 cfm at 1.2 SP
c) in real world usage it will do about 30 cfm at 0.,60 SP.
I posted a link right under the statement ... here it is again ... actual testing shows otherwise:
https://www.techpowerup.com/forums/...-vs-conductonaut-liquid-metal-73-w-mk.229167/
2. Yes, i saw that after i had posted and read the rest of thread ... here's how i use it:
CPU and CPU_OPT Header => Twin water pumps
CHA_1 Header => Phanteks Hub No. 1 => (6) 140mm 1250 rpm fans on 420mm rad
CHA_2 Header => Phanteks Hub No. 2 => (4) 140mm 1250 rpm fans on 420mm rad
CHA_1 Header => Phanteks Hub No. 3 => (6) 140mm 1250 rpm case fans
a) All fans shut off when CPU temps are < 40C
b) Use the Ramp functions to have Pumps slowly respond to changes in temperature over 30 seconds
c) Have Rad Fans slowly ramp up in response to changes in temperature over 15 seconds and down over 90 seconds ... this removes latent heat from coolant
d) Have case fans respond up and down over 30 seconds.
e) Fan curve starts fans at 40C at 325 rpm and ramps up to 850 rpm at 70C.... never gets there in daily usage w/o running a stress test, usually tops out at 650ish. Fans will ramp up during stress testing to 100% at 80C ...have yet to break 78C
I expect once tested, that cooler will be as good or better than the D15, Scythe Fuma ... that means it will be better than 98+ % of the CLC type AIOs on the market ... and if you test with a noise limit ... say measure temps at 40dba , it will toast every single AIO on the market.

Go to 23:00 mark ....
Corsair 100i CLC Type AIO = 73C @ 68 dbA
Swiftech H220X OLC Type AIO = 65C @ 43 dbA
Noctua Air Cooler = 70C @ 33 dbA
The all copper OLC type 240mm AIO kicks ass on the CLC 240mm AIO delivering a whopping 8C and to get that close, the CLC AIO has to be 5.7 times as loud. A sound pressure level of 70 dbA is the equivalent of a vacuum cleaner at 1meter ... a sound pressure level of 40 dbA is a quiet library
The air cooler kicks ass on the CLC 240mm AIO delivering an impressive 3C and to get that close, the CLC AIO has to be 11.3 times as loud. A sound pressure level of 70 dbA is the equivalent of a vacuum cleaner at 1meter ... a sound pressure level of 30 dbA is a quiet bedroom at night
Moving on to the 24:15 mark where max npise is limited to 40 dbA ....
Corsair 100i CLC Type AIO = 76C @ 39 dbA
Swiftech H220X OLC Type AIO = 67C @ 40 dbA
Noctua Air Cooler = 70C @ 33 dbA
Well the air cooler can't even get to 40 dbA
The advantage of the OLC over the CLC jumps to 9C
The advantage of the Air Cooler over the CLC jumps to 6C
So yes, I can certainly understand that the CLC has an aesthetic attraction to some and if they want to live with decreased performance and lots of extra noise, I'm fine with that. But the claim that they have a performance advantage is simply not supported by test results.
At equal costs .... no CLC comes close
At equal noise ... it's rare for a CLC to come close
Unrestricted it's rare thing for a CLC to match or beat the better air coolers
You can take it up with the manufacturers but ....
a) Scroll down to 100% PWM ... that's the pump Im using, i can't imagine a PC water pump that beats that much and it tops out at 12 psi
https://martinsliquidlab.wordpress.com/2012/01/29/swiftech-mcp35x2-pump/6/
b) These valves are typically set to open at about 4.3 - 5.7psi ... remember the diaphragm area is small, I am guessing is about .33" in dia ... so an area of about 0.35 sq.in ... so the max load at 5 psi is going to have a force of about 1.7 pounds
c) It really doesn't matter

This is not like a pressure vessel where you want to maintain pressure and open only when a maximum value is exceeded. Air is trapped in the top of the tube ... it actually doesn't ever need to be closed... it can breathe letting air in or out. As there is no way for more coolant to get in to the closed loop, no real need to worry about water rising in a closed system. ore properly, it's called a pressure equalization valve as negative pressure differential is no less of a danger than positive. We design water and water water system and in these instances, when water can and does rise, the float will rise and close off the air outlet. I use these all the time in pumping systems and it's a similar principle.
I first used one for PC water cooling in the 1990s and several times since ... I have never found one to need or even have a means for adjustment....nor heard of anyone doing such with any forum compadres. The fact that 99% of folks with a custom loop don't bother is a testament that the sketch above works. Water doesn't expand that much over the temperature range typically encountered in a custom loop, air does ... In a properly designed loop, coolant won't vary more than 10C ... highest I have seen was 39C when I turned the fans off.
Here's a description from Aquacomputer
"Pressure equalization membrane for top-side mounting in a reservoir. The membrane permits gas exchange between the cooling loop and the surrounding air, while preventing coolant from escaping. With this membrane, pressure changes caused by temperature variations can be equalized continuously. When installed, the membrane must always be positioned in the air bubble of the reservoir. "

The larger the volume of coolant / air within the loop, the more likely you are to benefit from such a thing .... however the use of one I think comes more from being a typical nerd (if there's a gadget I'll buy it) than any actual real need. I don't know why these CLCs are exploding ... my guess is it is more likely caused by thermal expansion in the metals as they see much wider delta Ts than custom loops ... I have heard of folks seeing 20C+ Delta T between ambient and coolant temps and Im guessing, it's a fitting or solder seam that can't hand;le the expansion.
