people stating high temps should look at their fans....maybe the fans not working as good at pushing the air through the rad thus cooling better
also try 2 for push pull...
some fans are dedicated for rads while most are for cases.
as gaiden and bulldog have shown (thanks gaiden for fan advice) is that currently the best fan for rads is the apache 120 s-flow which has a very high static pressure than case fans with the near exception of the 120 delta.
i didnt know about the static info till i was told about it as i presumed all fans were competing over cfm and dBA and as you may notice not many suppliers show Static Pressure rating (H2O) so then i decided to read it up and found out with rads S/Pressure is the beall endall and not cfm which diminishes when hitting the radiator grills although not all radiators have same design so some case fans may be okay for certains designs.
Akasa Apache 120 s-flow .... 26.4 mm-H2O....57CFM .....16 dBA
Delta 120mm Focussed Flow Fan ....24.9 mm-H2O....190 CFM ....59 dBAs
Most case fan ............1.0 to 4.0 mm-H2O......35 -> 88 CFM .......17-33 dBAs
so the apache is very highest on static and is quiet and constant with cfm not dropping when hitting rad.
so
high static pressure YES
low static pressure NO
anyone getting high temps shoult try better fans such as the apache and also better compound if using default supplied H5O comes with a preinstalled Thermal Grease Compound from Shin-Etsu which is average to good ...but these are beter --> mx-2 or 3....ocz freeze and artic-silver5 (being used a lot less now) but i myself use Tim consultants grease 0098 (winner of several thermal shootouts)
my thanks to gaiden and bulldog for heads up by the way
@Shocky-FM check what fans your using as the default corsair is merely average with low static from what iv seen... and im sure gaiden and bulldog will gladly advise you if you ask nicely
oh and having come from a black true extreme which i lapped to a mirror the H5O whilst not mirroe is perfectly fine and flat so maybe you might have banged it or it came damaged on the surface? it is easy to mark as its only copper...
