Water cooling the Asus Maximus SE X38

[p2501]

on my maximus formula my NB temps according to everest are 48c at idle
and on prime 95 it gets as high as 56c are those temps high?

As noted in this thread everything up to 47°C is considered safe. But this is just adressing the propability that your overclock may be unstable if you're going above these temps. Every board is different, so if you're stable then don't mind the temps. Northbridges are built AFAIK for far higher working temps than CPUs. Then again if you're watercooling your parts as posting in this thread indicates then I would guess you're doing something wrong. Maybe reseating?

Edit: The x38 spec sheet states a Tstorage of 150°C. I don't know why they're calling it so but I guess thats the max... (Tstorage low is -50°C, why would a chip be damaged by cooling it?)
