DS18B20 and metal surface temperature monitoring

Hi,

I have a question (pretty stupid indeed) about what side of the DS18B20 to glue on an aluminium plate (of course using artic silver kind of glue) in order to monitor correctly the temperature of it? 8)
If you have a better solution to do that, please feel free to add your suggestions.
Thanks

The flat side would be best, but that would cause some inaccuracy.
You better use a metal strip around the DS18B20 to attach it.
