Inside the PSU:

 

As we open this unit, please keep in mind that opening a Power Supply will completely void the warranty.  Not only that, but because of the large capacitors, you can suffer a serious electrical shock if you touch the wrong thing.  Please do not open your PSU to compare what the insides look like.  I'm a "trained" professional, meaning that I've got shocked a time or two and know where not to touch, and with that in mind and the smell of burning hair in the air, click on the images below for a closer look.

The PSU is actually quite roomy inside and allows for unrestricted airflow from the bottom mounted 140mm fan.  There is enough space to put in slightly larger components for the bigger models.  The cooling looks more than adequate for an 87+ rated PSU.  Even under load the PSU stayed pretty cool and we measured a maximum temperature of 54C during testing and remained fairly quiet.  The thing with high-efficiency components is that they give off less waste heat and actually don't need as good of cooling as poor quality units.  I was impressed to see that the dual-mode thermal control worked very well.  With an average load of 350W, the fan doesn't even spin up and this PSU is absolutely silent.  After prolonged 700W+ load, the fan spun up and kept the internal components quite cool.
