what's a cheap northbridge heatsink for an old motherboard?

[CP5670]

The fan on my old Asus A7M266 board seems to have died out at some point. It had a square plastic plate for a heatsink and there was no thermal material between this plate and the chip, so it's questionable how effective the fan was anyway. What's a good cheap ($5-ish) replacement for this? The NB-1C looks potent but this is just a backup / old game machine and I don't want to pay that much for something like this.

epoxy + random passive heatsink = winner

no need to worry about clips/mounting devices, just stick it on

thanks, that zalman one looks good for the price. This board has the mounting holes, so it should fit without problems.
