Passive Northbridge cooling for nForce2 motherboards?
Hi,
I'm wanting to quiet down my PC's and the next thing to go is the northbridge fan. Currently I run one board at 185fsb and another at 166fsb. Both are currently cooled by Iceberq chipset coolers and I'm looking for passive replacements.
Any thoughts on the Thermalright NB-1 but without the fan as a passive cooler.
My other option is to cut up an old Taisol cgk760002 copper based aluminium cpu heatsink to make a couple of northbridge coolers and bond them on with some epoxy.
I have good ambient temps (about 15-18C) but no real airflow other than from the 80mm CPU fan as they are bare systems in an open rack (no cases).
So would the NB-1 without fan be sufficient or do I need a bigger HS?

That might work, but I would probably go with one of the Zalman NB heatsinks instead. The thinking being that the Zalman's were designed from the ground up to run passively, unlike the Tr which was designed with forced airflow in mind. If you compare the two, you can see that the Zalman uses much larger spaces between the pins, which is generally better for passive cooling. Price-wise, they're about the same.

Yep. Zalman is the way to go for straight passive cooling, or you could almost go with the Swiftech like EdNg (for overclocking, also made to be passive, but you can mount a fan on top if you wish). Only go for the thermalright if you want to have a fan on there, it doenst work very efficiently passive.

I was only able to use it fanlessly because it was so close to the fan on the CPU cooler...
Otherwise, while it may be more effective than the NB-1 when run fanlessly, I'd make no bets on it performing better than the Zalman in terms of degree C rise over ambient/$, once price difference is considered.

Reducing the chipset voltage made a big difference to temperatures for me http://www.silentpcreview.com/article164-page1.html
