KSW:
That is my theory on the whole cooling thing:
More flowrate to WaterBlock the better (up till a certain point where more won't do you any beter. OR you blow up your waterblock
Lower flowrate through your radiator the better (again up till a certain point)
Reasoning behind my theories:
Heat transferes through ossmosis; bot sides want to come to an equalibrium. When a hot object is placed next to a constant cold object, the heat is transfered by ossmosis to the colder object in order to reach equilibrium. The hotter the first object, the faster the transfer INITALLY! After the first few moments, the heat transfer rate will drop logrithmically till it finds equalibrium with the second object OR the enviroment (most likly a combination of both)
In a nut shell; Place a chunk of hot metal in a freezer. The object will cool rapidly at first, then will start to cool slower as the metal begins to get closer to the freezers internal temperature until finally the metal reaches the freezers internal temperature. The greater difference in temperature between the mediums, the higher INITAL heat transfer between the mediums.
My therory capitalizes on both sides of this equation:
Higher flow rate through the block (should) capitalize on the instant cooling benefit from a cooler medium (the water) making contact with a warmner medium (the waterblock). Once the heat is "collected" in the water, it is immediately moved away from the medium you want to cool (the waterblock)
NOTE: Flowrate and surface area BOTH play a vital role in this section; an optimal balance between flowrate and surface area needs to be meet to capitalize on optimal cooling efficence HOWEVER in most cases, more is better.
The slower flowrate throught the radiator is the exact opposite. Since the difference in temperature between the water comming out of the waterblock and the environment (air), the lower the heat transfer between the two (because the two mediums are not that far apart from equilibrium; thus slower ossmosis) SO with this in mind, the longer the water is in the radiator being "cooled" by the active airflow going through the radiator, the closer the water temperature gets to the ambient air temperature being passed through the radiator. (This also explains why you can't get below ambient temperature without another method of cooling, such as phase exchange or pelts). Now, the closer the water temp gets to ambient, the greater the difference between the waterblock temp and the water temp, therefor when the water finally gets back to the block, the greater the difference between the two temps, the more effecient ossmosis affect you will recieve when the water "moves" the heat away.
UHHHHHHGGGGGG! (that was a LOT of typing
OK........ now that I am done saying MY theory about "cooling" does anyone have something against my logic?
