Nice

Drew M., Newegg
21 April 2011
  • Summary: Pin fins and mounting method design makes this heat sink forgiving to motherboards with poorly placed chipsets. Great purchase to replace those stupid 40mm fans on a lot of chipset heat sinks.
  • Pros: Fit onto my old MSI Neo4 Platinum SLI (MS-7125). Removes the heat from the smoking hot nForce4 chipset Price
  • Cons: Bottom surface is blue anodized; should be bare metal for least thermal resistance

Works fine

Alan R., Newegg
14 April 2011
  • Summary: Wish I bought it sooner and hadn't bought a fan first.
  • Pros: Attached easy. No moving parts, so it made no sound (obviously). Seemed to work well. Nice color.
  • Cons: No problems.

works great

Jesse S., Newegg
29 November 2010
  • Summary: Replaced an anemic/loud MSI K9N4 SLI motherboard fan. I have been using it for more than 3 years without issue.
  • Pros: Works great and cools better than the stock motherboard fan I replaced. The low spot was just perfect for clearing my video card.
  • Cons: None

Worked for me, need a dremel

Benjamin G., Newegg
2 September 2010
  • Summary: They are much bigger than my stock heatsinks, If you have a large CPU cooler and a poorly placed north and southbridge, a dremel might be needed to remove some fins. I measured and knew this beforehand, make sure you do the same.
  • Pros: My Motherboard had those super tiny annoying fans that made lots of noise an didn't move any air. I replaced them with this guy and had better cooling with no noise!
  • Cons: Mounting hardware felt a little clumsy. I have been using it over a year with no issues so I guess I can't really complain.

Just What I Needed

Joshua P., Newegg
8 July 2010
  • Summary: The fins are fairly tall, which got in the way of my video card. But it's not a big deal as the fins can be bent out of the way. It's not really a flaw.
  • Pros: Northbridge fan went out on a motherboard. This was very easy to install and dissipates the heat very well.
  • Cons: None

  • Summary: This is very tall. That can be a problem depending upon your motherboard chipset locations. I have used this for the following: 1. Cooling nForce 4 chip on Foxconn NF4SKAA-SLI motherboard. It blocks the end of the second, lower 8X PCIE VGA slot. Forces the use of short video card in that slot.
  • Pros: Replaces noisy fan cooled north bridge and south bridge heatsinks. Additionally, it can be used on some older VGA GPU's, with proper case air flow. Highly adaptable mounting arms for different mounting hole spacings.
  • Cons: Very small arm mounting screws, as many others have mentioned.

Worthwhile replacement for OEM fan & heatsink

Jason O., Newegg
25 May 2010
  • Summary: Used this to replace an Asus southbridge chipset fan/heatsink combination because the fans continue to burn out. OEM heatsink was small and made out of copper. After pulling the old fan/heatsink out, this was pretty simple to install. The screws are tiny though, so be careful.
  • Pros: 1) Inexpensive 2) Silent since it has no fan 3) Fairly easy to install 4) Performance. As others have stated, it dropped the temperature of my southbridge chipset from 34 to 24 degrees Celcius.
  • Cons: 1) Supplied screws are tiny, must use jewelry sized screwdriver. 2) Had to remove motherboard to pull out old fan/heatsink to put this one in. 3) Still needs case fan to be effective. No case fan had temps go into the lower 40s, with case fan temps are in the mid 20s.
