IC7 northbridge cooling mod

batboy · Nov 11, 2003

I'm working on my second IC7 mobo and wanted to do a very simple little cooling mod without all the heatsink cutting and fitting like I did with my first one. I also have been hearing about the occasional N/B cooler clip pulling out on some mobos. So, I decided to just permanently Arctic Silver epoxy a Zalman ZM-NB32J onto the chip. I was also shocked to see that only 2/3 of the northbridge chip was touching the stock heatsink (according to the "footprint" in the thermal goo). The final touch was adding a Sunon high output double thick 40 mm fan on top.

damn!!! that looks sweet

. did you get the sunon separately? Im still using the new NB cooler that comes w/ the IC7.

Yeah, I've actually had that Sunon fan for a while, was running it on my old TH7-II mobo's N/B chip. I think they're still available.

Just for kicks, I decided to stick a small heatsink (that I had laying around gathering dust) on southbridge chip.

I want to repeat, when I took the original stock heatsink off the N/B chip, it was not making full contact. I wonder if the reason some people can't hit high FSB is because some of these are mounted sloppy at the factory?

that maybe the case, and its just making enough contact to just run stock, and thats about it

gave up on butchering an ocz copper heatsink. ordered an expensive swifty 159 nb cooler. i wonder whether it was worth it...

batboy · Nov 12, 2003

Those Switech N/B heatsinks sure look impressive. Let us know how it works out.

i have seen postings in the abit forums about those loops pooping off, so i wouldnt hang a cooler on them... unless u use epoxy as well...

I see on Microcool web site that NorthPole is ready for Intel northbridge cooling... It looks interesting.

Looks very high tech. Wonder how well it works? They should of latched it down on all 4 corners though for safety.

screws....

what kind of screws are those that you used to attach the fan to the heatsink?? they look like #10 wood screws???

batboy · Jan 13, 2004

#10 machine screws

LuckMan212 · Jan 13, 2004

ah ha...well I was close

I just ordered up some AS5 adhesive + the same Zalman cooler. couldn't find a source for that sunon 40mm so I got a couple of slightly different ones but 1 of them should work........

Sunon KDE 40mm Mag-Lev

LuckMan212 · Jan 13, 2004

those #10 screws, they look like 1.25", is that right?

When ever I get a new MoBo with a NB sink I ALWAYS change the paste on the NB before I even put it in because of the Non-Coverage reason.

gruvin2 · Jan 14, 2004

Man now you all got me thinking i need to check my NB cooling. Well its cant hurt to look. I'm just so darn lazy :-/

simpleman · Jan 14, 2004

my epox came with a nice sized NB heatsink without fan, so i took it off and only about 40% was macking contact,
i replacet that heatsink with a blue orb. then i noticed my stock sink was about the size of a 40mm fan , and bingo perfect fit, so i slapped that 40mm on it and put it back on with AS5 looks nice,
simple, and more efficant that that blue ord.

That’s a sweet mounting mechanism. Looks original.
