Is my temp normal?

I have a 1/2" system w/ eheim1250 and RBX.
my temps are 43@idel 55@load

my mobile barton 2500 is currently oced to 2.6ghz @1.8v.
It seems like my temps are much higher than rest of you guys..

What are you ambient temps like? What size of Radiator are you using with what type of fan. Have you tried reseating the block to see if it was making full contact? What type of thermal paste are you using?

I've also got high temps while using the RBX on my mobile---I'm usually around 42°C load with 20°C ambient. I've discovered that if I FOLD continuously, my water temps gradually rise to around 10°C over ambient and my block keeps my CPU 10°C over my water temp as it should (.10 C/W as advertised). I'd really like a bigger rad to keep my water temps down, but I'm already packed in a mid-tower...
