how u apply the thermal paste is also a big factor..when i first bought this achilles 1284, i apply the stock thermal paste all around the cpu (my first time ) mayb the layer too thick or the stock thermal paste sucks...my cpu temperature becomes even higher than using the stock cpu cooler (around 45c idle)...i took it out yesterday..clean it and apply tx-2 compound just a dot (i mean quite a big dot ) on the cpu..and now my idle temperature is just around 37c..so damn big difference..
