Ahh, i forgot i had limited EDC value. Once i maxed that out, i saw much higher temps.The 420 wouldnt fit in my case but the 280 would in the top.
What sort of max temps are you getting with the 420?
I wonder if I should replace my Noctua U14S with an Arctic Liquid Freezer II 280 which is £90
That said, the 420 is operating at around 4-5c lower temperatures than the 360 from what i can tell.
