The fans  on these sticks  may not be  good.

One now shudders making noise  and vibrating the stick.

I pull the two fans and now use external fans  all is well in fact better then when I ran with the little fans  also not as loud.

I can not find it  but someone else  said their fan  became unbalanced and vibrated.

This happens even though  the fan screws are tight and correctly installed,
