Hey I got a q6600 with a xigmatek s1283 in an antec 900. O'ced my cpu to 3.2 with temps 45c under load. When I was stress testing my cpu hoping to get 3.4ghz with decent temps, my xiggy's cpu fan started screeching pretty loud making it unbearable when I'm sleeping. My question is how good is the Scythe S-flex compared to my stock xiggy cpu fan? Should I get the 800rpm, 1200rpm or 1600rpm version?
