Help: high temps for antec h20 620 / intel i5 2500k

[rsl1989]

i am a new oc'er and just built my 1st gaming pc.
i have a intel i5 2500k setup with watercooling antec kuhler h20 620; and i have the 620 running dual fans in/out

from youtube videos of pcwizkid his i5 setup with air cooling;
and also with funkykit's review of antec 620 : thier temps range from 25'C to 32'C at idle, at stock 3.3ghz
http://www.funkykit.com/component/content/article/8152-review-antec-kuehler-h2o-620-cpu-cooler.html?start=5

i plan on overclocking it to 4.5ghz but i dont want to yet because my temps seem too high....

i used artic silver 5 thermal paste with above listed setup and my idle temps are between 38- 41'C in idle
and 70'C when 100 load with prime95. my case is the Rosewill Future gaming case, which i have 4 120mmfans intakes with plenty of vents / mesh for outake

would i need to reapply new thermal paste, or use diffrent one, what could be causing this.. please help any advice?? does AS5 cure time affect this...

What's the temperature in the room when your running 70c? Does the temperature improve with the side panel off?

Are you running stock speeds and getting these temps, or is your chip OC'd?

FYI...just because you have 4 fans, doesn't mean you have good case airflow, however this would be more an issue of the fans on your LCS radiator. What fan(s) do you have on it? What direction are they blowing?
