Initially when i got my Ultra120ex out of the box, i though my unit is weird, dont u guys notice that its like somewhat... "senget" a little? apparently this one is the same as well

nevertheless, ive used both Ultra120 and Xigmatek S1283, definately ultra 120 is slightly better, not by a huge margin but its definately better despite the bad mounting mechanism. Also, another thing to note is that, ultra 120 responds to low noise/cfm fans better than the xigmatek, well.. i guess you get what you pay for.
