Not sure what Rad and cpu block to get - Page 2

post #11 of 12
How are you planning to mix subzero temps and fluid with large rads and high speed fans? Where is the subzero temp coming from and why are large rads moving a heap of air? Radiators in subzero systems are normally submerged in a super chilled fluid rather than open to airflow. They would only warm a chilled fluid with air.

The guys that test rads use the systems they do because they know what they are doing. Using a single performance metric of fans for comparison like static pressure or flow rate leaves a lot of room for error. Radiators create a sliding curve of resistance to airflow, as flow rate increases the static pressure required to move air through increases. A 100CFM fan with extremely low static pressure will fall very low on this curve and move little air through the rad. Equally a very high static pressure fan with a low max airflow to achieve that SP will fall low on the curve too.
In general the airflow through normal rads is pretty close between fans at the same speed. Most high static pressure fans achieve that figure with high speed and consequent relatively high flow rates. Only Very airflow optimised fans with very steep blade designs will show a very significant difference.

10-15kBTU mini split A/C.. larger the surface area colder liquid gets before it goes into loop. huge radiators so it can go from hot to cold.


and thanks for clearing the fans up
