hmm scan messed up my order and didnt send the cooler
which was a good thing because i realised the first thing i should do with a noisy crappy fan is to clean it !!!
cleaned it and its quieter and cooler (for anyone else reading look for decent youtube video tutorials on how to clean fans and heatsinks) idle temp of 23C doesnt go over 35C at load plus i have it OC from 2.4ghz to 3.0ghz
i also cleaned my two big case fans (which ive had disabled for years because they were noisy) and now they are quiet enough to have on all the time and provide extra cooling woohoo
now i need to take a shower, the amount of dust was ridiculous even tho i thought my rig was relatively clean
