Thermal grease. I guess that must be part of the solution. I didn't put any on the p4 chip . About the case temperature, it's hot too, 45 degrees celcius. When i take the cover of the case off, the temperature drops by a couple degrees. But not much though. When i put my hand in the case, it doesn't feel that hot. Only when i put my hand next to the cpu fan, do i feel the hot air coming from my cpu, and believe me it's HOT. I'll see what i can do. I think i'll buy some grease, but about the fan configuration, i cant do much about it. All the rear fans occupy the available space, plus i dont think it would be wise to make em blow air into the case, right?

thanks anyway, cheers
