5 out of 5 eggsGreat Cooling Option

Pros: Good Quality
Allows my E-350 to be fanless now (aside from 1 case fan)
From fan to fanless actually dropped my APU temps.

Cons: Mounting takes some repetitive adjusting but nothing unbearable.

Other Thoughts: Two of these coolers fit on my ASRock E350M1/USB3 AMD E-350 APU. One for the APU, one for the northbridge.

5 out of 5 eggsperc 5/i

Pros: Works with the perc 5/i with some tweeking of the hook mounts.... Think that it will do JUST FINE.

Cons: had to tweak it to fit dells non standard 2.5 inch hook spacing but it does work but he fan of fins is not exactly 90 degrees to the card.

Other Thoughts: Its big.... and takes up slots below your raid card your attaching it too so be prepaired...

1 out of 5 eggsWont fit

Pros: Nice design, includes most common mounting clips and a tiny (and i do mean TINY its about enough for 2 applications MAYBE) tube of thermal paste

Cons: wont fit most asus boards due to the weird northbridge design and im not willing to epoxy it on. so it only gets 1 egg for this one as its not a universal design. i would give it 1/2 egg but newegg wont let me crack one

3 out of 5 eggsMine was missing parts

Pros: As a heat sink, this thing works great. I have not had any overheating problems since I installed it. And the added bonus - where I had a noisy fan before, pure silence.

Cons: The cons are that despite the packaging claiming to have two different mounting brackets (both screw and loop hooks), as well as Zalman's web page, my package was missing hooks. Neither Newegg nor Zalman was able to correct this situation. THOUGH, I was able to adapt and make a workable solution.

Other Thoughts: Despite the parts missing, I was able to make this work for my needs. The results were not as good looking as I would have liked, but it works. In terms of performance, I have no complaints (5.0 performance, 1.0 in parts, 3.0 average).

3 out of 5 eggsExtracts heat well

Pros: Does a very good job pulling heat off the North Bridge chip for a passive radiator (fanless). Thin design clears CPU heatsink.

Cons: Like some others have said, the little nuts do not slide into the mounting rails at all. I had to puts the bolt heads into the rails and keep adjusting the supplied mounting arms until they set over the MB holes. Very tedious, delicate job! You must be sure the face of the heat sink is flat over the chip on the board!

Other Thoughts: If you can repair wrist watches, you will have no problem installing this heat sink. If you do not fair well working with very tiny parts, it will be more difficult to install. For the money, it's ok.

5 out of 5 eggsNice but be advised

Pros: Really nice design
Big and have lot of heat dissipation surface
High performance for AMD and Nvidia chipsets.
Fit on MSI 870-G45

Cons: Painfully to install
Sometimes nuts are too big and doesn't fit into the rails.

Other Thoughts: 1 of my nuts was too big and i needed a pair to plier to force it into the sliding rail. took me about 20 minutes to fix and install this thing but once installed the temps are really impressive, went from 40c idle 60c load to 30c idle 40c load on a AMD 770 chipset.

5 out of 5 eggsWorks on Asus A8N-E Northbridge chip

Pros: It works just fine.

Cons: None

Other Thoughts: Used Arctic silver epoxy to attach this item to my Northbridge chip (permanently) after the tiny fan stopped. Chip was overheating and causing problems. Been in over a year now and it is working just great. And of course it is "solid state" ;o) so there is no noise from it.

4 out of 5 eggsno NB thermistor, so...

Pros: Inexpensive. Mucho surface area for passive cooling. Micro fine mating surface finish. Cool blue aesthetics. Once finally installed it has a nice fit. Manufacturing quality is very high on this aluminum part.

Cons: Pain in the back side to install, as many others have mentioned, so I won't waste more text on that. Manufacturing tolerance on the little nuts is not sufficient, causing one to move too easily in the track and the other requiring mucho force to slide it through the track. The quality of the attachment hardware could definitely use some improvement, although the attachment design itself is sound, allowing utmost orientation flexibility.

Other Thoughts: Unfortunately I can't comment definitively on the cooling performance as I don't have a thermistor on my 440BX Northbridge. However, considering the tiny stock green aluminum NB block on this mobo didn't even have TIM (thermal interface material--i.e. paste) between it and the chip, and the fact that it would get smoking hot during heavy load, I'd say this Zalman is working much better. It remains cool to the touch with both processors running an instance of burnP6 for 5 minutes, whereas the old heatsink would be very hot to the touch.

I've got excellent front to back cooling in my Codegen server case. Wetting my fingers and placing them a couple of inches behind the Zalman shows there is plenty of airflow through it. Wish this BP6 mobo had a Northbridge thermistor...

5 out of 5 eggsWell I'll be, my heat sunk...

Pros: Having tested/used quite a few, I can honestly say this may be the best aftermarket passive northbridge heatsink out there. Large chip-contact surface area, plenty of heat spreader surface area, does exactly what it is advertised to do. I have my CPU overclocked and my NB FSB @ 2600 MHz and it never goes over 29C even under load!

Cons: Didn't come with Arctic Silver 5 ;)

Also, not too much of a con, but the universal mounting brackets and tiny screws took a little patience to work with. Take it slow and steady and make sure your work area is clear and well lit.

Other Thoughts: Noobs: after removing the stock heatsink, if your northbridge chip isn't just one solid uniform piece and there are a bunch of little metal pieces surrounding it, DO NOT put this solid metal heatsink directly on top of it. Those little pieces are conductive and need to be insulated. If you don't have the same kind of special insulating foam handy that is most likely on the chip-side of your old heatsink, electrical tape will do the job. Do not however insulate the actual chip in the center. If you use conductive thermal paste like Actic Silver, make extra sure that none of it gets on those little pieces, just the center chip.
