Which ones I should consider, and which ones I should not

[ame]

I'm currently running Q6600 at 3.0 ghz using Termalright Ultima 90 with a very slow 120mm fan is a Solo case.

I didn't want to go any higher since I still value silence over GHZ. and I also want temps to stay well below 60. (currently 52 at full load)

Now for your list

AC freezer 7 PRO is the ONLY AC product I can recommend Its value for money is phenomenal. The Freezer extreme is junk IMO (have it installed in 2 systems and its fairly quiet but sucks at OC - lower clocks than its smaller brother).

OCZ Vendetta 2 is also a good option. So is Xigmatech 1284 (1283 is more suited for Q6600 IMO)

Both TermalRight coolers are very good but are priced higher. If money is no problem my choice would be TRUE but make sure its 775 and not 1366(i7) as you have in your list (should be cheaper too).
