Good NB and P4 coolers?

[Robster]

I've got the IS7 motherboard. And as for many others, the NB fan has begun making weird noises n stuff like that... And eventually it will die i guess.

So i'm looking for a new product to replace that one.. Either a heatsink or fan.

Im looking for something that cools very well, but does not make too much noise. The same goes for my P4 2,6GHZ. Ive been using the fan (Intel's) that came along with the processor when i bought it (retail). But I want to change that one too, makes too much noise.

Any ideas?
Thx.

EDIT: Btw, the temp of my CPU now is about 45-55C. Normal?

I have the same board, and the NB started to funk out too. I just unplugged the fan, the NB heatsink seems to be able to handle it passively.

I put a Swiftech MCX159-R on my NF4 chipset and it's running amazingly cool.
