I'm not sure of the best place to post this. The heatsink on the Northbridge chip on my Asus P4PE, rev 1.03 motherboard has broken loose. The system was built in 2003 and I still use it occasionally due to some specialized hardware/software so I'd like to keep it running.
The heat sink is normally compressed into place with a pair of spring clips across the heat sink, hooked into loops soldered into the motherboard (links to photos later). However, those 2 of those loops pulled out of the motherboard so the spring (and therefore the heatsink) popped loose.
This could have happened a long time ago, as far as I know. The system still works OK, and maybe the heatsink on the NB was primarily for overclocking, which I'm not doing, so maybe the lack of heatsink isn't a problem. Still, I'd rather try and address it.
Looking online, these loops pulling out of the P4Pe MB is a known issue. There were several online discussions about it in the 2004-2005 timeframe. Back then, there was a kit available but that was a long time ago.
Photo 1 is just to give some perspective of where the heatsink is on the motherboard for the zoomed photos that follow. Photo 2 shows where the hooks for the spring clamp pulled out of the motherboard and the heatsink is essentially floating. Photo 3 shows the northbridge chip and the heatsink on its side. Photo 4 is a closeup of the northbridge chip, to figure out what to do next. Photo 5 is a closeup of the heatsink top and bottom.
What would be the best way to fix this? I was thinking I would scrape off the thermal foam (the yellowish outer square on the bottom of the heatsink, and the pink inner square, neither of which have any adhesive properties to them), and maybe buy some sort of thermal adhesive/epoxy to glue the heat sink to the top face of the NB chip?
If that sounds reasonable, do I put the thermal adhesive around the die, or actually cover the die with it?
