awwww nOoOoOo dont start putting doubts in my head now after I went through so much trouble (getting help off my dad to order the stuff online - Its an up hill battle since he doesnt like using his credit/debit cards online incase his details get stolen or something.) just to get this Xigmatek over a OCZ Vendetta2 which i coulda got from my local hardware dealer that reportedly also had the same issues with it not fitting in the 900 case
the whole reason why i shunned the Vendetta2 was because of stories that it might not fit in the case....now im back to square one....
I personally would have recommended the Big Typhoon VX, not because I happen to own one but because I know it doesn't have any clearance issues in the Antech 900 case. I'm running one in mine and it will even fit with a side panel fan in place.
It may even be better than the tower coolers in the 900 because the Typhoon thrives on th e air intake from that side panel. Here's a couple screenshots with 4 different temperature monitoring programs, Everest, Coretemp, Speedfan, and Sensorsview. The first is at idle, the second at load under Prime95.
Not bad for $50 at the local CompUsa. I can't believe I'm the only one posting in the club that owns one.
Edit: Oops I should have checked your system specs before posting. However I'm guessing you have to original Big Typhoon with the single speed 1300 rpm fan. If so why not just invest in a higher cfm fan and replace it would be cheaper than a whole new heatsink, The typhoon should cool as well as mine does with a ~80 or 90 cfm fan.
