Ever since I built my first SFF almost 12 years ago ~mid 2006 my long term goal has been building a fully passive one.
At first, my interim goal has been a single fan systeem, at the lowest fanspeed possible. This was already considerably quieter than the regular tower I used until then.
Then, when SSD's became affordable I replaced my 3.5" HDD for a duo of 2.5" SSD's about three years ago. That made the system significantly more quiet.
Now, with the advent of the AMD 2400G I want to try my luck building a fully passive system. For that, I'll need to bring down the power usage significantly from the cTDP of 46W. My estimate is I need to roughly half the power usage. For that I have a few options to my disposal:
1. disabling one core
2. disabling SMT
3. disabling turbo
4. downclocking from 3.6 to ~3.3GHz
5. undervolting
Since I'm not a gamer the thermal headroom will not be used by the GPU either.
At this point, I'm still waiting for my RAM to arrive, but next week I'll probably be able to install the mainboard into its case.
The 2400G installed on the Asrock Fatal1ty AB350, with the Zalman CNPS8900 (fan removed):
This is the SFF where it will go into next week: Nexus Psile
Let's see how I will fare in my quest :-)
