Great Cooling Option

Mike K., Newegg
13 January 2012
  • Summary: Two of these coolers fit on my ASRock E350M1/USB3 AMD E-350 APU. One for the APU, one for the northbridge.
  • 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.

Wont fit

Anthony B., Newegg
22 April 2011
  • 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

Mine was missing parts

Ronald B., Newegg
30 March 2011
  • Summary: 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).
  • 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.

Extracts heat well

Curtis C., Newegg
28 January 2011
  • Summary: 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.
  • 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 ...

Nice but be advised

Maxime H., Newegg
17 January 2011
  • Summary: 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.
  • 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.

Works on Asus A8N-E Northbridge chip

Edward S., Newegg
10 January 2011
  • Summary: 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.
  • Pros: It works just fine.
  • Cons: None

no NB thermistor, so...

stan h., Newegg
6 January 2011
  • Summary: 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.
  • 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 atta...

Well I'll be, my heat sunk...

Anonymous, Newegg
18 November 2010
  • Summary: 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.
  • 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 ne...
  • 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.
