Need to quiet down the northbride fan on IS7

[grabadude]

It spins about 6000+ RPM, much faster and louder than retail P4 cooler (2400 RPM). What is a good way to lower the speed without doing any modifications (installing heatsink, etc) ?

You could try unplugging it, many non OCd board will work without a fan. Alternatively, you could try getting a fanmate or a controller like it, a male plug to splice into it and then plug the fan into that and the fanmate into your PSU. This would always be reversible.

I used a Zalman Fanmate I had lying around. That shut it up.

what about the zalman passive northbridge cooler?

EDIT: oops, that prolly counts as a mod

Without any modifications to the board? Buy a Fanmate. Or if you don't have the money, just 5V the sucker. Even a Delta Black Label will clam up if you feed it that amount of juice. Get a 4-pin Molex (HD connector) to 3-pin (Fan) convertor/splitter. Rearrange the wires so that the red wire of the fan connector goes to the yellow one on the Molex. Presto, 5V of juice and a much quieter fan.

Someone else suggested the big $5-$8 Zalman passive heatsink, that is my vote as it is just swapping heatsinks. It really isn't much of a mod, much easier than 5Volting the fan. Otherwise, you could get a Zalman FB123 bracket, and aim that nice 92mm fan at the Northbridge and take the fan off of the northbridge heatsink. Little fans are horrible!! The smallest fans I tolerate in my case are 8cm.
