the question:
"There has to be a spot where everything is as optimal as it can get and there will be a certain temp between the water temp, air temp, and CPU temp. This number should remain constant through various wattaged ext.. "
now we are going to focus on the word
optimal, eh ?
while it is tempting to think/believe/hope that there exists a single 'best' solution, such will be ever elusive
and the reason is simple; given that CPU cooling is the end effect of the interrelationship of a number of factors, then it is clear that different 'manipulations' of those factors may yield the same (or effectively indistinguishable) results
those not having followed Cathar's quest (20+ pg thread on OCAU) are encouraged to read it
here
as most of the variables are discussed (or perhaps cryptically alluded to)
consider Intel's general description of CPU cooling:
a cascade of gradients
if one focuses VERY hard on EACH of those individual gradients, the means to better cooling solutions become clear
as do the very real limits
to look to the wb alone for better CPU cooling is to see less than half the 'problem'
what about that TIM joint ?
and worse yet, what about the impending arrival of IHSs for AMD CPUs also ?
a cascade of gradients, indeed
returning to the wb (only, and it is
less than half the total thermal impedance):
in an absolute sense it can be viewed as a coolant delivery problem, as #Rotor has understood for some time
but few are willing to address the problem in only those terms because of the cost
so now we begin to wander through a literally endless series of combinations and permutations of compromises all related to economics
-> but we do not describe our activities that way, in an honest fashion
we gussy-up our economic compromises with 'technology' bs, thereby really confusing the issue
I am working on several 'high tech' approaches quite different from conventional CPU wbs, but they are also 'high dollar'
an additional note re the originally phrased question:
all my testing to date demonstrates that there is NO change in a wb's performance due to changes in the applied power - period
(as long as the die size is the same of course)
$Rotor
go back and read how I defined T/W, using a RTD or TC embedded in the wb bp
you otherwise include the TIM joint which is an offset - and a variable
