Zalman CNPS7000A-AlCu vs Thermaltake Silent Boost

Just picked up an OEM 939 3500+ (prices are skyrocketing and the retail was 30 dollars more!) so i'm going to be needing a nice HSF for it. My hope is to run it at 2.4ghz (3800+) quietly and cool. From what i've gathered, the Zalman CNPS7000A-AlCu and the Thermaltake Silent Boost seem to be the best performing quiet coolers out there. I have't been able to find any good reviews or threads comparing these two coolers. Which one of these coolers would serve me best? Any other suggestions are welcome too.
 
I boiled it down to these two also before buying. I got the zalman 7000A-AlCu and I couldn't be happier. The thing is inaudible outside the case on the highest setting and it performs incredibly well.
 
I have the silent boost k8, and im nto really happy with it....its dead silent....but it just doesn't cool that well.
 
the zalman cnps7000 is realllly nice and quiet. but isnt the pure Cu version even better than the alcu version? and also the new "B" versions even better?
 
WTF... no contest the Silentboost dosn't stand a chance against the Zalman. The 21dba rating is a lie.... plain and simple.

Yep, pure copper version is way heavier but performs a bit better. B revision is slightly lighter, comes with Fan Mate 2 and has longer cables.

Tt SilentBoost K8 is not that great IMO. Its cooling capacity is clearly lower than Zalman's, even though I find the cooler pleasantly quiet.

Another nice alternative is Gigabyte 3D Cooler Ultra GT (GH-PCU31-VH). It's a huge copper heatsink with adjustable fan speed (from silent 2k rpm to hurricane-like 4.5k), good cooling capacity and impressive looks (4 blue LEDs).
 
Hmm the gigabyte is intresting. Does anyone know how it would compare to the Zalman in terms of cooling capacity? Also, is it super heavy like the Zalman Cu?

The gigabyte should easily beat the Zalman at higher speeds, I'm not sure how they compare at lower RPMs though. Also there is version of the gigabyte that use AL fins rather then CU and performs within a few degrees (not carried by newegg).

You know, there are many reviews around the net and opinions tend to differ... However, it seems that the Gigabyte cooler beats Zalman at high RPMs but then it sounds worse than the infamous 5800U dustbuster. It still cools fine at lower-mid RPMs though where it's on par with Zalman.

Yes, it is very heavy. It weighs 780g so disassembling the heatsink before transporting comp is highly recommended. As for its quality, it's really impressive. The copper surface is well-polished, the 3.5"/PCI panel is nice and the mounting mechanism is solid and stable. It also comes with high quality thermal compound.

Here is a review of the AL fin version that weighs in at 430g, it can be purchased at Buy.com for $33.

For referance here is a review of the CU fin version done at the same site.

If weight or price is a concern get go with the AL version.
 
According to the charts/reviews, the Thermalright's seem to be the best at cooling (most effecient). So why not use a quiet fan on a Thermalright?
 
Well the thermalright SLK948u is a great heatsink, its just a better heatsink when paired with a higher CFM fan. I have my SLK948u hooked up with a tornado and it works well, however I dont know how well it would work with a silent fan. To me it sorta defeats the purpose of having a really good heatsink paired with a fan that doesn't put out much CFM. I had the silent boost before I switched to the thermalright, it worked well at idle speeds but when the processor hit full load the fan just couldn't keep up, and i was skyrocketing to like 57 celius.

I haven't had any experience with the Zalman but im very happy with the thermalright.
