Northbridge fan

I have a KT7A RAID mobo. The northbridge fan died. I took the fan
off. There is a base that I suspect can be removed. There are two
plastic tabs on opposite corners.

Are these just push pins? Other than just pulling them, is there a
trick to get them off?
 
From pictures I saw they look like the pins you need to squeeze together on
the downside of the board and pull up at the same time

Yes, squeeze the ends together, by using a pair of pliers on the part
of the pin that extends below the board. Once you've compressed the end
enough, it can be popped up through the hole in the motherboard.

Examples of potential replacement coolers. Note - for all of these, they
have a min and a max spacing between mounting holes, that they can handle.

Thermalright HR-05 - two models, uses heatpipes, passive or active cooling.
Looks like it could handle 10-20W chips, especially with a fan fitted to it.

Which you select, really depends on how much heat the Northbridge pumps out.
Older motherboards are much more modest with their heat output, than modern
boards. Some of the old motherboards were fitted with fans, when a fan
really wasn't needed.

I guess that means I will have to remove the mobo to get it off?

Thanks

Yes, that's the message. You don't want to damage something,
so remove the motherboard and give the end of the pin a squeeze
so it'll go through the hole.

Sometimes, you need to reuse the pins, so just cutting them
off is not to your advantage.

The idea of the pin, is the tip spreads, after it has been pushed
into the hole.
