Thanks for the help everyone I sadly saw your post too late boogschd and did it like GlaG said for now. >.< Though everything seems to have worked out quite well, I currently run between 36-38°C idle with a ambient temperature of 34°C (I live right under a roof with no A/C...) and from what I got that it's not bad at all. On normal load I also barely can hear a noise increase so mission accomplished I guess^^
