i'm new here, but am seeing the same problem everywhere.
i think the models in general people are creating are 2 complacted to be sloved without hardcore pc power.
but i think a much more simplistic approach can be taken to the problem(s)
depending on what you want to solve for. the system for water cooling is very simple, more complex then just air. but not as complicated as we think.
to supper simplify we can, neglect heat transfer from the pump (esspically inline) and any heat transfer threw the tubing.
what we get is basicaly a 2 radiator system.
heres how it goes.
water flow is marked by ==>
rad1====>rad2===>rad1
we have a closed loop system, that after its running is steady state.
now from steady state anaylis we need to know a few things
a) mass flow rate of water, and the themral porpties of water. (from any themral book)
b) mass flow rate of air, and air temp( temp should be considered constant throughout a given system
c) the thermal energy being put into rad2 from the cpu
since almost all the system specs are known there are a few things that need to be added into the caculations to get accurate results, and that is efficency.
we need efficeny numbers for the transfer of heat from cpu to water, and from water to air.
these numbers can be assumed, or estimated, to try to get a worst case seniaro, or can be eventually obitaned threw data we get from people using various blocks/flow rates etc. then doing a best curve fit. also i'm sure some of these numbers are known somewhere, esspically for the rad for water to air. since these are ussaully car heat cores, and data for them should exist.
water blocks seem like a different problem, since finding data on them would not be possible as they probably have not been tested as much as the rads.
the top amount of heat from cpu, in watt/hrs can probably be found from like amd, or intel.
so anyway, what in the end we can find out, is most likely both water temps on both sides, and from the get an idea of what the cpu temp's will be like. i'll work on equations later, but after there sloved should be plug and chug
