Blue orb or fan on stock heatsink for KK266 Northbridge?

[otl]

Would I be better off using a blue orb or a fan on the stock heatsink on the Northbridge of an Iwill KK266?

If the blorb, what would you use to attach it - the supplied tape? Since the mounting holes are 60mm apart, it wouldn't seem like the approach in link would work. (AS epoxy might be better, but I don't have any - and it seems like overkill for a chipset cooler...)

If you'd just attach a fan to the stock heatsink - what sort of fan, and how would you attach it? The heatsink appears too shallow (and small) to use a normal clip or screws.

I would go with the blorb, and nylon string to hold it there.
thermal tape is kinda poor, and would bring the performance down to the stock cooler lever .

How about this....

Northbridge HSF

I used a 55mm Alpha HS and a 20CFM Top Motor 50mm fan...it keeps everything nice and cool @ 167 FSB.

If the link does not work, copy the URL and paste it into another browser window..damn angelfire..

The link using the 3mm washers is a good one, and should work. I would not want to put Arctic Silver Epoxy on one since I just had to RMA a KK266-R recently. BTW, IWill has the best RMA service that I have had the pleasure of dealing with for a long time. I called them, was issued an RMA #, sent the board back by Priority Mail, and had a replacement on the way back 2 days after IWill received the one I sent.

i am just using some double sided tape and sticking a 40mm 486 fan on it. i dont plan on going much over 160fsb, so it should handle it well(duron is on its way)

Well, (assuming that the washers being talked about are insulating, since there are vias and surface mount caps near both mounting holes that would short otherwise) the major problem I see is that you'd likely have to use an even larger washer than the 7mm in the article. On the "lower" hole (the one nearer the memory slots) that shouldn't be a problem - there's plenty of room. However, on the "upper" hole (the one nearer the PCI slots), the "fan aux" header (J42) is very close and would possibly block a larger washer. Nonetheless, I will see what washers I can find to see for sure. Unfortunately, it looks like you would need to pull the existing HS to check, and I'm not sure you could reuse the removed hold down pins to reapply it if necessary. Oh, well - such are the problems of hardware hackery...

The Article called for 3mm washers, not 7mm. As for removing the stock heatsink, it is not difficult if the board is not installed. I just used my fingers to press in the catches on the plastic pins on the back of the board, and pulled them out. It was also no problem to put them back on. There was no thermal compound on any of the KK266-R NorthBridge chipset heatsinks that I had at all, and it is a good idea if overclocking the FSB to apply thermal compound even if you use the stock heatsink.

EDIT: I see that the outer washer diameter is 7mm, and the inner hole diameter is 3mm. I planned on installing a blorb on a KK266-R that way today anyway, and I will post back and let you know how it goes.
