Re: [OT] Acceptable CPU temp?

["Geraint Morris" <lists@xxxxxxx>]

It may well work as far as transferring heat goes but compared to Artic
Silver it isn't terribly good.

Artic Silver has a thermal conductivity of greater than 8 W/mK, standard
zinc oxide stuff is less than 1 W/mK.  A higher value here is obviously
better.

Of course if your heatsink isn't up to dissipating the heat then it doesn't
matter too much what you use.

Check here for some interesting benchmarks
