A great advantage, in my opinion is that the CPU fan direction PC-top can be installed where for me 2 case fans diligently raking in air (see picture in the product description).
Cool my Phenom II X6 1055T now since about 4 months with no problems
At idle, the CPU runs at 36-38 ° C, under load to about 46-48 ° C, at room temperature between 24-28 ° C
Can not tell you how the boxed cooler is compared, because I've never used it, but believe that the Freezer brings significantly more cooling capacity.
"Whisper" is the Freezer 13 only at BIOS-level control 1, at level 9 (the highest), I'm happy about my god Schallhämmendes headset :)
Operate him in setting stage 4 with good tolerable volume and above temperature values
I hope you could give a bit of decision support, the purchase is up to you but yourself
