Passive cooling an i5-6500, Nuts?

[ElectroBlaster]

If I wanted to build an ITX with an i5-6500, would I be asking too much to have it passivley cooled in a custom itx case? The case has a bespoke heatpipe setup including the side walls acting as radiators.

Everything in it will be running at stock.

The case is an Minisys-T8 and the blurb says 65W max. Looks like im pushing it to the edge maybe?

It is being built for general usage, business stuff etc.

It will spend its life as an office business related machine, browsing, videos etc. The current rig is really struggling with things now (Abit AI7 sk478).

My initial plan was to use an old s775 board and xeon L5420. This one sits at 50w so its not much off the 6500. So things changed when I grabbed an Asus H110i Plus D3 and the 6500.
