Let's talk about pressure!
Why is a high pressure of coolant good for a waterblock?
Why is a low pressure of coolant good for the rad?
Here's hoping that the following individuals will join: pHaestus, gmat, gone_fishin, JimS, Sirpent, redleader, schoolie, jtroutma, and MeltMan.
This starts with gmat's statement:
Now, it goes without question that higher flow rate means better heat transfer. Why ?
* Increased turbulence
* Higher contact rate between water molecules and rad walls, less "dead spots"
* Better temp gradient through the *whole* water circuit because it's "averaged"
* My fluid dynamic courses are so many years behind i can remember everything
Since putting rads in parallel will divide flow... No good.
gone_fishin has also provided some good info.
Here's a recap:
Facts:
1-Ambiant air is at (around) 20C.
2-Coolant temp is increased by the power emitted by the CPU.
3-Coolant is cooled by transmiting its heat to the metal that composes the radiator.
4-The rad cannot lower the temp of the coolant below the temp of the ambiant air.
5-The heat from the coolant is transmitted to the metal of the rad at the same rate, regardless of the rate of movement of the coolant (given the same temp).
6-The rad lowers its metal temp to the ambiant air.
7-The fan helps the above purpose.
8-The rad will dissipate more heat from the coolant, if the coolant is hotter.
Anyone?
