Youre probably one of the first Swedes I've seen in here... welcome, from a "neighbour" in Denmark!
Which CPU do you have? If its a FC-PGA, I think you have to choose the FOP, but a Duron or T-Bird can use both. I've seen a review saying that the taisol performed VERY well, and wasn't as noisy as the FOP38.
I have a fop 38 on my 1.2ghz t-bird. It keeps it 10C cooler than my pld Alpha 6035 with the sunon fan.
The Alphas rock with a delta fan but are expensive.
The fop 38 is a great HSF for the money.
I just ordered a OCZ twin for my t-bird 800, wanna see how far I could OC it.
