As its name says the Mini Typhoon is rather small compared to other massive coolers. With its six heatpipes it still looks like it can keep up with some heat load.
On both sides I found those small edges. They are pretty sharp and can easily damage cloth, or even hurt you when you are unlucky.
Thermaltake uses a 92mm fan on the cooler which is held in place by four standard screws. So it's easy to replace it with your own fan.
With the fan removed you can see the all copper fins which radiate heat from the heatpipes.
