    Hi there,

    a couple days ago I wanted to optimize the air flow on my Powermac G4 MDD 1,42.
    I have added a SilentX 120mm fan on the back of my G4. With that action I also thought I would be a good idea to check on the dual CPU's and put new thermal compound (Arctic Silver) on, in the hope to gain some degrees on the heat issue.

    Unfortunately I got the exact opposite now, instead of having a cooler running system, I lost about 3 degrees - my system is now running on 57C and not on 54 like in the past. :mad::mad::mad:

    Now I have read somewhere that the thermal grease is getting better after some weeks ?
    Does anybody have experience with it ??? Did anybody replace a G4 or renewed the thermal grees on a G4 ??

    I would love to know, because I am not sure what I can do? Maybe I did something wrong, maybe the Arctil Silver compound is crappy or I didn't bolt the CPU back down in the right order.....

    Any ideas ????
