“Must have and easy to install.
Has thermal paste on it already.
Once you update Ubuntu or Raspberry Pi os it will make the fan not run continuously and only run when needed. Not very loud at all once firmware / os updates applied.
This cannot be used at the same time as a case mounted active cooler. Example rpi oem red and white case and Cana kit turbine fan case.
There is also only one power port for a fan so unless you make a 2 way splitter cable only one fan can run.”
