Looks pretty good, but i think you could get an ax-7 for $14 and have good temps, with an 80mm fan which could be quieter too. Either one, but beware of the thermaltake one, you might want to see if you can find a review since it is new, I havent seen one yet, hopefully it is better than there other products.
Yeah the ax-7 is made for lower cfm fans. The fins being wider then in say a slk-800 help the lower cfm fans since there is not at much resistance so the fan doesn't have to be as powerfull. I am currently using on a computer i made for my friend and with a 35cfm fan its doing a great job, and you can't beat the price.
That thermaltake setup blows. I have a 1700xp pali and idle temps are 43C. It is decent for the price i guess, but i'm not overclocking this chip. Although airflow isn't as good as i'd like it to be inside the case, the hsf is crippled by the clip. Because the clip goes directly over the core, you lose a lot of cooling performance. If someone were to modify the hsf so the clip no longer blocks airflow, the HSF would perform much better.
I would also suggest the AX-7 as opposed to the Thermaltake...
Especially since the "Price is Right"...
(Wishing they had been that cheap when I bought mine... )
Great cooling for little cash and easy on the ears as well...Go AX-7.
