    If fan bearing is worn-off or sticks due to dirt residue, once its blocked 5-15 seconds and it burns through...

    For me, this is easy: if its more than five fans in case or stock cooling is not efficient -> water cool. Laing, 12mm tubes, 360 / 240x240 or passive like MORA - and done.

    This performance seems nearly get nulled by recent llvm changes .

    Don't have time to bisect this, but it is somewhere in the last 20ish days between svn213451 and svn211669 .

    On low power Kabini (that is why maybe i can more easely spot any perf little regressions ) overall perf goes down by 5-7% when i compare those two mentioned llvm snapshots.

    I will try now daily llvm, maybe only that snapshot regress slightly .

    Nah the same with svn213730, but don't care much for now... i see some patches in mesa git which can reduce CPU overhead maybe better to test how that goes

    With those performance goes up by 2-3% in Xonotic for example

    Well I might have been wrong after all.
    Since 3.16 became stable, I thought I'd try again, but all I got was a computer crashing...
    So I tried this time with a different card, and now it works fine (minus tearing in videos...).
    Why? I'm not sure, maybe the previous card was defective? or the power cable I used for the previous one did not work somehow... I'll keep testing of course.
