Ok, so I went out to a few stores and bought some chipset cooling kits. The thing is that there were these aluminium "crystal coolers" that either were 40mm or 50mm, and there was a fan of 50mm, so that wasn't the correct size. I believe after reading and looking at my case, that I can either install a brand new heatsink fan combo, or just replace the fan. The weird thing is that the heatsink is glued onto the Northbridge and then these nuts are screwed at each end, so I guess it would just be easier to replace the fan or use some other type of cooling. Now, the 50mm fan I bought is too large, so I will return it and get a 40mm fan. I looked at the OLD fan, and it seems that the screws were just screwed INTO the heatsink plates, like the screws just went into the dividers of the heatsink which I thought was weird because I thought there would be actual holes for the screws on 4 sides (top left, top right, bottom left, bottom right), but it appears the heatsink that the motherboard has, has no holes for the screws, and you just screw them into the dividing walls of the heatsink so they just stay in place....
And also, there are also some designated chipset coolers designed especially for my I845 chip on the newegg, so I might TRY those, but that would mean I have to take off the heatsink and glue onto a new one....
