Hello vrokolos,
Big Shuriken is better than stock cooler but you have a i7 860 ... Why you using a i7 860 for htpc/multimedia...._? This typ of cpu are not for this segment
.
But you can use Big Shuriken and fit on top a normal Slip Stream for example with 25 mm thickness. This will have more airflow and the temperature will drop more. Big Shuriken is only 58 mm height.
