Hi the SunFire V210 psu fans is not a long lasting one !,as i figured.
have ~150 v210 running and changed 9 psu's in 1½ years.
they tend to break after about 6 months.
it has 2 so the box still is still ok running only warmer on one fan.

"can i call it trouble v210 still running ok with users,
when i want to change psu or fan, not hotswappable."

any suggestions: bying new psu's for spare ?
already ordered 2 not delivered yet.

buy new: quality 40mm.("1.57) fans as spare ?
i think i have to do both !

anyone have experiance on lowering temp by removing
frontdoor/backdoor of a sun 9000 racks ?
