Better HS? Alpha PAL8045 or the Thermalright SLK900A?

Just curious. I have the Alpha PAL8045 and recently purchased the Thermalright SLK900A. If I were to use the same fan (80MM) on either cooler, which cooler do you think would work better?

TIA,

The alpha has more surface area the SLK900A has more mass... who knows... a guy over at overclockers.com does this with a panaflo la1 80mm and got great quiet results from the 80mm...

I bought the SLK900 to use the 92 mm fan, so I could go even quieter, but I'm realizing that the 92 mm fans for the noise levels that I want aren't going to give me any more cfm than a good 80 mm fan. Plus, because the fan is bigger on the 92 mm fan, there is a larger dead spot in the most critical area of the heatsink. If I do use the SLK900, it will probably be with a 80 mm fan as well.

Why is everyone going nuts over the SLK900? Is it because of the capability to use a 92 mm fan? I'm just trying to understand why someone would pick it over the Alpha hs.

Thanks again.

i only got one because it was $20... no way i'm paying $40-50 for that thing before.

True.. That's why I bought it in the first place. I don't even think I would've paid $30 for it because I really didn't need it. I did pay about $30 for my Alpha heatsink back when I bought it. I was just wondering which one was better is all with the same 80 mm fan on it.

Thanks again.

I'd wager the SLK900a has the edge by a degree or 2 over the Alpha. My 8045 beats my SK7 by 2-3C, which would put it about on par with a SLK800. I use a Panaflo U1a @ 7v on it, FWIW.

What's a Panaflo U1a? Did you mean to say L1a?

If I'm cooling a non oc XP2000 with the SLK900a, what fan can I get away with? I'd like to go as quiet as possible. I'm thinking about trying a NMB 17 cfm fan, but I'm not sure if that will cool it.
