The retail package of the RTNV HDD cooler from Titan looks typical and rather simple. There are two stickers at the bottom that promises up to 23% reduced HDD temperature and 13% less noise.
You need to cut the hard plastic shell in order to get the product. Rather simple procedure.
The external material is aluminum and basically are two big plates that joined together via screws.
Turning the plates upside down it unveils the two thermal pads at the plates that contact with the HDD and transfer all the produced heat to the aluminum heatsinks. Don't forget to remove the plastic flee first and before you place the HDD!
The next step is to place the HDD. Just push it a bit until the disk's top surface reach the thermal pad. Afterwards you need to place the other plate and use the included mounting screws to get everything in place.
On the rear side there is enough space left to attach all the interface and power cables...
