3 hsf, 2 processors... which match with what?

[Rippsnort]

I just purchased a 2100+ XP retail box, and a
ALPHA PAL8045 HEAT SINK & FAN ATHLON 1900+ 2000RPM 32DBA 39CFM
and some Arctic Silver 3 thermal grease

and would like to use them togeather on my new Asus A7N8X, but I need a second system running a 1.4 Thunderbird. Right now it is being run under a CAK 38 copper heatsink with a Delta (37.6CFM, 46.5dBA) fan @ 50 degrees using Hardware monitor on my Soltek.

My problem is noise, the 1.4 Tbird needs to be quiter.. I had purchased a Thermaltake TT-6025A 31CFM fan (28dBA) to put on the copper heatsink, but most people have told me that it doesn't have enough air flow (delta is needed for CAK 38's).

MY questions:
Will ANY of the following scenarios work on the 1.4 Tbird system?

1) The CAK II 38 with the thermaltake fan..
2) The retail 2100+ heatsink with either the thermaltake or the retail fan..
3) Underclocking the 1.4Tbird, and using 2100+ heatsink with thermaltake or the retail fan..

Thanks

you could get a 60-80mm fan adaptor, it would push more air with less noise.

The GlobalWin should work great on your 1.4 T-Bird, and nix the adapter: they illicit too much backpressure and actually impede airflow and thereby cooling, in addition to generating more noise.

The stock 2100 amd cooler should work on the 1400, likely with either the thermaltake or stock fan. Your CAK might be OK, too, the problem is high resistance to flow from the narrow fin spacing...

Bear in mind that the 1.4 Athlon's are about the hottest cpus you can find; the stock cooler will be less effective on the 1.4 than it would be on a 2100+, for example.

The article here shows that the Heat Dissipation in the 2100+ Palomino is only 0.1W (72.0W) less than the heat dissipation in the Thunderbird 1400 (72.1W). So can I assume it doesn't matter which processor I have running, and that it only depends on the heatsink/fan combo and of course a little dependence on case cooling..

Not to be harsh, but isn't that what I said before? Use the new retail hsf on the 1400, the nice new alpha on the 2100.... put the cak with its screaming fan in a drawer, or give it to a deaf computer enthusiast...
