Recently, I've been monitoring my northbridge temps by sticking the temp probe in the middle of the stock heatsink and i'm finding idle temps @ 131f/55c and load temps @ 140f/60c - which seem a little hot to me.
I haven't pulled the heatsink or removed the CPU/fan shroud and re-applied AS5 yet, to see if that makes a difference.
In looking at some of the reviews of the Microcool & Swiftech coolers, they list initial idle temps around 116f/47c & load @ around 137f/58c before HS install. It looks like you can't use the CPU/fan shroud with either of these units, so I'm going to have to commit to my earlier experiment of removing the shroud & installing both 92mm rear fans to exhaust in order to bring the northbridge temps down.
Anybody here fooled around with NB chip cooling yet?

I just replaced the Dell-gook with AS5, but other than that, no. You have now sparked my interest, when I get back from Spring break I am going to see just how hot that baby gets.
Frankly, I find it hard to believe that the northbridge gets that hot but you never know. Darest I say that the northbridge could be a reason for instability?

I could be wrong, but as I understand it, the northbridge chip is in charge of FSB operations. I ran a deep virus scan & Half Life 2 at the same time and pushed the temp to a max of 140f/60c. Gary at Sidewinder said additional cooling wasn't necessary since we can't O'clock the Dell/Foxconn MB, but I'd like to see lower temps on mine.
If I stay with my CPU/fan shroud remove mod (after more testing) then I think I'm gonna attack this hot spot, and anyway the Microcool/Swiftech units both look too cool.

You are correct, sir, in that the FSB a part of the NorthBridge's duty. I also agree that most heatsinks (especially big blue ones) are totally sweet looking. When I get back ill see what my temps are. I have tons of air moving through my case, though, and I think it should be pretty low. Also, my room is constantly at 'arctic' temperatures cuz thats how i like it. =D

i put the zalman northbridge cooler on my gen 4 temps are 111 f at idle and around 127 f load. good deal for $8  |

Does the Gen4 have a fan-shroud like previous versions? If so, did you remove it? Do you have a link to that particular heatsink?

Ben, The Zalman Northbridge HS looks like a good, inexpensive compromise over the Swiftech/MicroCool units, and with the staggered fins, appears to fit with the shroud (which looks the same as my Gen3). Check out this thread; xpsmodz.proboards33.com/index.cgi?board=8xxx&action=display&thread=1109001105on the CPU HS. It looks like your Gen4 has the version "A" model with the copper heat pipes lined up in a row - the newer, better version? The white sticker on the top of mine (version B) says "REV A00". By the way, is that your modded fan stuck on the shroud? What kind? Munski |

With insufficient airflow over it the north bridge can in fact run hotter and fluctuate more than the 2.8 p4 here. I ran into that when using the remote thermistors and the fan controller (which I donated to C2) in the many different cooling configurations I ran. I handled that here when running the standard two heat piped dell head sink by having one 80 mm fan between it and the bottom of the heatsink blowing up thru the cpu heatsink. This pulled air up thru the north bridge heatsink. For added cpu cooling and air turbulance I also ran an 80 mm on top of the cpu heatsink blowing air into the cpu heatsink. This blew exhausted air out the top of the heatsink which was handled by two air vents I have cut in my chassis. One is across the top rear where the grasp handle is (runs horizontal with the rear plastic panel still removed and Nidecs mounted on the outside of the chassis) and the other is at the rear of the top (runs front to back). The new heatsink, hdds, vid card, and memory is going to require a rework of the chassis. I have most of it figured out in my head and on notepads and have started to immerse myself in it. The chassis is split all apart and I have done a partial rework of the internal cabling. The fan shroud on the hyper six is going to require some rework as well as the cdrom/hdd cages. Temporarily the satas are mounted at the top rear by the previously mentioned added vent holes. It should work out rather nicely..hehe...but there are details to tend to!  |

is the cpu cooler the hyper 6 from cooler master? ive heard some installations say to remove the mobo to put in a new retension bracket. did you have to?

Dev - I love your reply - you sound like Ed McMahan from the Johnny Carson show. Speaking of big blue monster heatsinks -  You should see the size of my biceps after this mod! And guess what - they color coordinate with the Zalman blue ones. Oh, joy - (HA!) Munski |

Yes..Yes...Confirmed...and thanks for helping to clear that up ED!
