So, swapped the wraith prism out for the dark rock slim.................................. :O Still in shock, what a difference!? Absolutely silent,(cant hear nothing over my case fans and they are 2 big 200mm) and my table no longer shakes when doing anything that stresses the cpu! Have also got better scores on cinebench and cpu-z with faster clock speeds and cooler temps. No more messing around with power plan settings,can just let it run and do it's thing. Would highly recommend this cooler for anyone having issues with the wraith prism.
