Great for oldest board with no heatpipe VRM cooler, etc...
Bracket installation (minuscule bolts and nuts requiring very careful mountage) takes me about 30 min just to fit it all corectly...
Keeps my northbridge cooler than the stock heatsink but was a pain in the *** to put in place...

It's well designed and it works for almost any mobo
I wish it came with a sticker. I didn't get one with mine :'(.
I really like this thing, you don't appreciate it until you get it in your hands and get a good glance. Its design is flawless; just like Zalman's CPU HSFs. If you turn the connectors and the push pins just right you can make it fit on a southsridge too if your layout is similar to mine.
I currently have it on this board
ASUS M4A89TD Pro ATX Motherboard AM3 DDR3 2 X PCIe 2.0 x16 CrossFireX USB 3 eSATA with a Zalman CNPS9700LED Blue & AMD Phenom II x2 3.3GHz BE 560.

The southbridge is now cooler and I feel confident adding additional drives w/o worrying about damage to my system.

stay cool, efficient
Too large(blocked all satas ports and couldnt install 2 sloter vid card on PCIEX 1) , very hard to install
Installed it on a NV4 chipset on a ECS kn1 extrem mobo. I had to sacrifice important fonctionnalities. My mobo died few hours after the install, however I dont think this cooler was related.

Appearance, price, brand
Design flaw, gave me a defective "nut"
I installed this on the nforce4 chipset of my A8N-E. Due to the design, there is limited space to put the little arms. You can't place them along the center of the side of the heatsink, which limits your install options.

Due to this, I had to turn the heatsink 90 degrees, which then conflicted with my graphics card heatsink, and the required modding took several hours.

Also, one of the nuts had the center hole off-center, and it almost made the netire product unusable had it not been for the fact that I had another spare Zalman heatsink with an identical nut, and broken nut worked with the other unit.

simple to use,
easy to attach
none so far
bought to replace a old stock cooler on my Abit IC7-MAX3.

way better than the stock cooler that it came with, plus that fan was way too loud, and had a very high pitched whine that I couldn't stand any longer.

Experience: 10 Months
No noise, no moving parts to break
Installation is tricky
Used this to replace the problematic chipfan of the Asus A8N-E. Apparently asus will ship a replacement fan, but no moving parts, no extra noise appealed to me more. Rather fiddly to install, but quite effective at dissipating heat.

Experience: 3 Days

-More affective than previous Nvidia NB fan cooler
-Complicated installation (unless ur an engineer)
This product works fairly well, though if ur using an Nvidia mobo like my 680i SLI, this product might (just might) not be enough for ur temperature ego. On the 680i NB, the Zalman is hot to touch (finger cannot touch for more than 3seconds). So if u want lower temps for ur NB, u'll need some good air circulation in ur case. btw, it took me an hour to install this Zalman.

Experience: 2 Days
Cheap, good adjustability.Works as advertised
Small screws can drive you nuts! Can be a little difficult to line up and tighten without losing your alignment.
I used this because my Xigmatek cpu cooler did not clear the stock NB heatsink on a DFI BloodIron mobo. Using this gave me the clearance and reduced my temps from 44C to 37C.

- Affordable
- Decent performance
- Sleek design
- Passive cooling
- none so far
Used to replace the chipset cooler of an aging A8N-SLI based PC. Temps are in my comfort zone (unfortunately I could not compare with previous temps - client PC).

Installation was straightforward. Good product.

Comment: "The tests really say it all. The performance benefits of this passive heatsink are a thing to be reckoned with. With zero noise it destroys the stock cooler on our toasty 8N-SLI motherboard. There will comes a time when the fan on your active NB cooler gives up the ghost, and without a doubt the be
