So the case comes with two 200 mm fans and a single 120 mm fan. Combined with the fan controller these should provide enough
airflow for most users while also staying quiet when needed. The 650D isn't really even marketed as a quiet case, and indeed even with
the fans running at their minimum speed the fans and the airflow are still easily audible. Maybe there could be another step on the
fan controller for even quieter operation? Also while the roof and rear fans are easily replaced by any 120 mm fans of your choice,
there are only mounting holes for a 200 mm fan on the front panel, which makes replacing the front fan a bit tricky.
There's very little difference in the temperatures with the fans running at minimum and maximum settings. In a sense this is a good
thing as it shows that even with the fans running at minimum speed the airflow is enough to keep the system cool, but it also means
that maybe the lowest fan speed settings could be lower still, making the temps a bit higher but also lowering the noise that little
bit more? Either way, the case performed well on the temperature tests.
Conclusion
PROS
HDD cages
Sturdy construction
Space for any GFX-card
Cable management
CONS
Could be a bit quieter
I've been waiting for the Obsidian 650D for a good while now, and was really excited to get my hands on it. The idea was to get
800D quality and attention to detail at more reasonable size and price, and the 650D pulled it off just as I'd hoped. The case is
significantly smaller and lighter, without losing too many features. For 4 hot-swap bays you'll still have to go for the 800D, but for
the rest of us everything is still there.
The layout of the 650D is my current favorite of all the cases I've reviewed. The Silverstone FT01 held this crown for a good
while, but compared to that the 650D drops the positive pressure cooling, uses larger fans, has better cable management, clever
HDD-cage and overall just that little bit more room.
