Summary: When the 40mm fan on my Asus motherboard started to sound like a coffee grinder, I looked around for a replacement. Rather than going for another fan, I saw this passive cooler. It has been in operation for several weeks and keeps the Northbridge cool. Installation requires removing the mobo to release the push pins, but other than that was easy with the included pins and heat sink paste. The brackets are easily adjusted for any hole pattern.
Summary: I bought this since I am changing my CPU fan and removing my mobo, I might as well upgrade my NB heatsink. On stock NB heatsink, my temps are around 31-32C(idle). Mobo is an ASRock A770DE with an overclocked NB on stock NB voltage. After putting this heatsink, temps went down to 26-27C at system idle. Overall, I'm very satisfied with this. For less than $10, it's definitely worth it.
Summary: Just built an HTPC and needed silence. The stock heatsink fan on my Asus MB was very noisy. Installed this in 10 minutes and silence has been achieved. Just remember you have to have the board out to remove the old clips from behind. The other thing to keep in mind is this sits pretty tall and will get in the way of your video card if the card is long and lined up with the PCI/Express slot. I installed a Sapphire Radeon 5570 and it was close!
Good cooler, although a little bit of a pain to get installed

Summary: I bought this to replace a fan that was dying on a northbridge chipset. Installing it was a little bit of a pain; it takes some work to get the clips positioned just right. On the upside, the ability to change the position of the clips means that it's possible to fit it on motherboard that don't have the holes in standard positions. Now that it's installed, it's working great.
Summary: This was given to me from a fellow tech who couldn't use it on their machine. I'd been considering purchasing some replacement for the chipset cooler on my old board so I figured this would be a perfect candidate for that. Dumping the parts onto the floor makes installing the cooler look rather confusing. It has brackets that are attached with screws and nuts, then the usual push-pins to install it.
Summary: My north bridge fan (that small one on your motherboard) was making noise. Probably because my motherboard is 4 years old the fan started to make super annoying buzzing sounds (They are not healthy for you!). I tried to cleaning it from dust and that didn't help either. After that I got pissed and I decided I'm going to do something about it. Either buy new fan OR I found this Zalman Fanless Cooler! This thing is just perfect. - No noise what so ever.
Summary: The heatsink installs easily if you have any mechanical aptitude at all. My motherboard temperature runs a little higher than I wanted but the quietness of the system is amazing. I have a quiet cpu cooler and a quiet power supply on my system. Again, all computers should be this quiet. I think this heatsink will benefit from a case design with dual case fans or at least a an blowing across the heatsink.
Summary: Client of mine brought his computer to me with a video issue. Found out his Northbridge fan melted with an extraordinary high loads. I replaced it wit the Zalman heatsink and it works great now and is able to take on the high temp loads.
