The northbridge chip, also known as the memory controller hub. is responsible for keeping the CPU, RAM, graphics processors and other motherboard components talking to each other and doing their job. On gaming systems and other computers that require lots of high powered processing, these chips generate heat on a level of that produced by the CPU itself. In an over-clocked system, stability is absolutely vital and every option must be considered to maintain maximum performance.

Like a CPU cooler, the Xigmatek Porter N881 is designed to remove potentially damaging heat away from the chip. Xigmatek technology includes the single, large, pure copper aluminum heatpipe which employs HDT, or heatpipe direct touch, to dispense with the heatspreader and thermal plate by putting the heatpipe directly in contact with the chip for optimal thermal transference. The heat is whisked to the aluminum cooling fins, which are offset from the base to provide clearance for other components and coolers.

The user's choice of an 80mm fan can be installed at their option for additional cooling or to improve airflow. The Porter N881 utilizes the same vibration reduction technology and easy installation people have come to expect from Xigmatek.

  • newegg Superior Heat Dissipation The XIGMATEK PTR-N881 features H.D.T. (Heatpipe Direct Touch) technology for efficient heat conduction, plus high-density aluminum fins for maximum heat dissipation. The unit also provides an option to add an additional 80mm fan for the best possible cooling performance!
  • newegg Easy Installation With a multi-application design, the XIGMATEK PTR-N881 provides user-friendliness and convenience for quick installation.

Sweet 5/2/2014 4:05:04 PM

Pros: Decent price and highly effective and did not have to attach a fan to it

Cons: I didn't have a Smurf near by to read the tiny instructions so I just winged it but having worked with similar after market heat sinks this was no big deal.

Overall Review: I had an Old school Asus P5NSLI and the Northbridge on it was pure junk and this thing would over heat constantly causing shut downs and reboots even with a decent case with good ventilation and 3 fans. This baby is pure gold to me and going to check other builds and order more for sure. Thanks XIGMATEK you guys did awesome here :)

XIGMATEK PTR-CN881 HDT Northbridge Heatsink 3/13/2014 5:02:39 PM

Pros: Looks cool, Antec Tri-cool fit like a glove on it. Nearly unlimited mounting options. It kept an overclocked North bridge 15*C cooler than stock. I'm a firm believer in direct touch coolers

Cons: Had to buy a windowed case so I can look at this puppy

Overall Review: Next best thing to water

Stop using Arctic Silver, its old hat 11/30/2013 5:31:35 PM

Pros: Copper heat-pipes can do no wrong.

Cons: None, the offset is good for big cooling setups.

Overall Review: I don't even own this product but I wanted to mention that xigmatech paste outperforms arctic silver 5. The stuff is old hat, you ought to get prolimatec instead. Everyone here should read this link:

Worth It 11/1/2013 6:07:48 PM

Pros: Well designed, put it in an older PC in a very high temperature environment. The CPU was shutting down a lot, after installing this it works fine and stays at a stable low temp. Would Recommend!

Cons: None

Overall Review: Good Product

Absolutely wonderful 7/24/2013 4:10:53 PM

Pros: Comes with everything you need.
Offset fins fit perfectly next to my CoolerMaster V8.

Cons: Putting in the screw under the fins was a lot of hassle.

Overall Review: The stock heat sink was a joke. 10 minutes of playing Fable 3 and I had to take a 5 minute break for it to cool down from 150F at the minimum settings. A fan helped only by reducing the cooldown time to 1 minute.
With this and no fan it rarely goes over 90F. I can finally play all my games at full for as long as I want.

Great heatsink 6/28/2013 8:25:41 PM

Pros: If you have the space, this heatsink is a must. I was easily able to take my dinosaur AMD 785G w/ integrated ATI (amd) HD 4200 and juice the little guy from 500MHz to 800MHz with a mild over-volt. I'm running it passive, but (for me) it was perfect because the my CPU fan blows air directly through this NB sink after the air made it's way through the CPU sink. Great product, and by the way it's designed, it should fit most NB applications. In fact, my NB is even support in the sepcs but I bought it anyways, and sure enough it was perfect.

Cons: The fins are off-set from the die attachment. I assume it was made this way to accommodate an 80mm fan. A fan isn't included, but the rubber mounts for one are included. Being that it's off-set, I could see the heatsink cause problems for a very limited number of individuals looking to use to in conjunction with other bulky substituents on the motherboard.

Looks Ridiculous but great next to Cooler Master Hyper 212 4/17/2013 4:50:28 PM

Pros: North Bridge has never been cooler. This can be a pro or a con, but It's huge, and looks ridiculous, but next to my massive 212 Evo, it fits right in.

Cons: My NZXT Phantom Original is HUGE and this thing is about an inch below the evo. If your case will not fit an evo, careful about buying this.

Overall Review: Used arctic silver 5

Be carefull 4/11/2013 8:20:35 PM

Pros: It keeps the NB cool and with out the optional fan it is silent if it fits your board.

Cons: did not fit my board the ASUS M5A97 LE R2.0. when aligned to the NB correctly the screw and nut were jammed so tight to the heat pipe that it was not possible to tighten them correctly.

Had to ghetto rig it in place after hours of trial and error i managed to align the pipe and the NB and screw it down. i wiggles in place. i an sure it would wiggle if i had not ghetto rigged it. not sure i feel good about the install. I may try to mill the stock sink in to a home made hybrid.
