I have an x4 750k and my idle temp was ~50C while gaming ~68C and i thought that it was high so i bought a new thermal paste(arctic silver 5) to replace the old one , i clean both cpu and cpu cooler very good and then i applied just a little bit (i had seen tones of videos in youtube) but unfortunately the temps went up ! Now at idle ~57C and while game maximum was 82C , i have already changed 3 times the thermal paste because the results were shocking and that didnt fix it . I really need help !
