Accurate temps are not that important. As long as the probe is consistant it will do perfect for what we do. We aren't keeping meat or semen, we're chilling hardware.... and the temps between systems are going to be relative at best with any cooling anyway.
... so pay no attention to how "accurate" the probe/thermo is. The purpose of using them anyway is to determine a cb/cbb threshold and monitor so the load handling of the cooling doesn't break down unchecked.
