so i ran prime again to test the cooling capacity but this time i set the clocks to 3.9ghz 1.3v (previously 4.0ghz 1.4v)

first ten minutes, ambient is 29c (but i think it was around 26-27c)





after one hour, ambient was a little cooler this time 24c





and idle after test



seems like with old fans are still fine, for now. once i add my gpu to the loop i need to have better fans
