amd sempron 2800+ socket 754 undervolting

i have a amd sempron 2800+ socket 754 on a SOLTEK SL-K8AN2E-GR which does support undervolting (which is why i bought it from newegg)

and i have it at stock speed (1.6ghz, 256k cache) undervolted to 1.075 volts, and while i've not tested it for prime95 stable, it is application stable.

i have the stock fan at 5v and stock heatsink. sisandra reports power consumption at 26 watts. at 5v cpu temp is 28C but without fan it climbs over an hour to 50C.

i've been thinking of getting an thermalright xp-120 which does fit SOLTEK SL-K8AN2E-GR and running it passive-fanless.

great info but what fan/hs are you using. any stepping on the chip?

yeah I would get the xp120 it might work passive if side blower or big fan in the back. post a pic of your case.

hi
don't know how to post a pic, though i would be happy to do so but currently i'm using the retail heatsink and fan, i am using the palmero 90nm D0 stepping core. fan is volted 5v, and temps are generally around 25C

thanks for asking

presumably your 25-28*C is at idle or 'normal use' since u haven't done any priming?

..anyway, with that sort of temp on stock cooling @5v, and taking an hour to get to 50*C, i would have thought that a XP120 would easily be able to handle it passively, atleast in an open case scenario (ie handling only the actual cpu heat, and with no secondary airflow) it may even level out just above 50*C with stock HS (how much is safe for this core??).. in the real world the heat of other components and confined spaces would make it a more complex question.. and weather or not u'd have any secondary cooling eg case fans, psu fan? (and what that is)
i'd think 100% fanless would be possible-- with the right components..
