1. VERY few reasonably priced HSF-s are advertised for 754. Since I am not the most knowledgeable person on the web, and I keep my searches to "754 HSF". That is what I came up with under 40 bucks. I saw others between that one and the $40 HSF-s, but it was the same exact design.
2. I can always grab another HSF after purchase.
3. Not too worried about overclocking. I will start overclocking the chip once it ceases to perform to my satisfaction.
4. I am working with a budget. I have 300 bucks, with S&H included, to make my decisions.
5. After further review, I have decided against the DTR unit, and am getting a 3100. I am not interested in dealing with all the issues involved. (Fragile chip, lack of heat spreader, need to modify HSF to fit)
You aren't thinking sempron are you? They cost the same as the 2800, and are the same, except they have 1/2 the cache disabled and no 64 bit registers (also disabled). Why pay the same for less?
If you are not OCing, or only a mild OC, the stock hsf on the A64s are great.
I have a s754 3200, running @ 2.45ghz, with the stock hsf. Even under 100% load 24/7, my temps have never gone above 52c. My enermax psu has a very large bottom fan, which is important.
