Passive cool 754/939/AM2

[Toytown]

Hi

I have a small HiperMedia case for a small server. It looks like a small DVD player so fits in well with the rest of the stuff pretty well, its only 53mm high and fits a micro-atx board.

Ive currently got a 775 Celeron 2.5ghz in there, but looking at changing it to which ever AMD 754/939/AM2 processor (im guessing AM2) gives the lowest heat output.

Does anybody have any ideas if any of the AMD's can be passively cooled with a very low profile heatsink and am i right in thinking, that any of the low end AMD chips have got to be cooler than the celeron currently in there. With the low profile heatsink/fan in there at the moment the celeron runs around 60oC at idle (lol), i can adjust the fan to cool it to around 46oC but due to the small size, makes quite a lot of noise......hence the change of processor.

EDIT - Server uses very very little CPU power, hence the celeron

Yep. The AMD's do run much cooler than Celerons you are right there. The only decent(i think?) HS which will passively cool an AMD chip is a Scythe Ninja and that would be if the chip was underclocked or something. The ninja is also huge so i don't think there is a smaller one. You might want to look into water?

I doubt it would cool passively, but a sempron would produce the least heat and be plenty fast enough. Also have a look for the "NorthQ 3390 Slim Line Media Center Cooler", AFAIK only one place does it but it looks like it is capable of cooling sempron witht he fan at low speed.

btw it only lists socket 754 and 939 but it should be ok on AM2, youw ould have to contact them to find out. You could also get a 3000+ on socket 939 and underclock/undervolt it to lower heat output.

Water cooling in the hiper media case isnt really a viable option, it is only 55mm high. The ninja would be able to cool a lot of the single core CPUs passively without temps being too bad, doubt you would have to undervolt them but it is about 4x higher than the case

Didn't know that lol thanks
