To give you a better idea of the sizes involved, this front of case shot shows how a full sized CD-ROM drive dominates the internal space of the casing, leaving barely enough room for a motherboard to fit beneath it.
So how does it run after shoe-horning the system together?
Booting up the system and leaving it to settle for 10 mins before taking some temperatures, we can see that it starts off initially quite acceptable at 41 deg C.
This is expected form a compact system where airflow is restricted and there are a lot of heat generating components close together (HDD, graphics, CPU, PSU).
After running Prime95 for 10 mins on both cores, we can see the temperature shoots right up to 67 deg C which is worryingly high for a system that can't exhaust heat as fast as regular systems can.
I feel that the system setup might be a bit too compact for this fan, with the need for more intake and exhausting fans to keep the heat down. Prolonged running of the system under load could easily result in thermal runaway and potentially damaged components.
I suggest to anyone building a slim system that if you choose this HSF to consider your airflow carefully and maximise it where possible.
