Thank you buddy ! Will do. I disassembled old one and OH BOY, this is first time in about 5 years I did that I mean I clean case all the time but what I saw inside was not-describable. Like a pound of dust so thick it became a tar like substance. Anyhow I realized there are 2 fans. One over RAM another one for actual CPU cooling and only 1 is making noise. I mean not really both do , but only one was really REALLY loud. So for now all I did is took other one out and re positioned it so it cools CPU instead of RAM. So now it's manageable noise levels. Still ordering 2 new fans cause I forgot what silent computing is. Once again thanks !
While I am doing all this I wonder if I should remove whole thing and reapply thermo after so many years it may lost some of it properties.
