Thermaltake company decided to offer a compromise to the mainboard manufacturers who have to provide their products with large capacitors installed just at the side of the processor Socket A (if you remember, some mainboards didn’t allow using Orb coolers at all for this reason). So, the company announced that they would manufacture a smaller version of their famous Super Orb cooler (see our Review for details). Namely, the cooler will feature smaller diameter and will be called Mini Super Orb. In fact, the two brothers look very similar to one another. Here is a comparative table for your reference:

Parameter	Super Orb	Mini Super Orb
Diameter	69mm	65mm
Height	74mm	74mm
Rotation Speed	upper fan: 5000rpm lower fan: 5500rpm	upper fan: 5000rpm lower fan: 5500rpm
Noise level	upper fan: 30dBA lower fan: 28dBA	upper fan: 34dBA lower fan: 28dBA
Heatsink Material	Aluminum 6030	?
Voltage	12V	12V
Thermal Resistance	0.66C/W	0.60C/W

As you can notice, a new cooler is not only smaller but also features higher thermal resistance. To tell the truth, we don’t quite understand why. It is very likely to be due to some other material used, though there is no mention of it anywhere. Moreover, the cooler specs are rich in puzzling discrepancies (take for instance the Inner and Outer fans specs). That’s why we suggest taking time and drawing the final conclusions a bit later, when we see the Mini Super Orb with our own eyes.
