I need to solder back the fin to the pipes and was wondering if soldering paste is better than a soldering iron or if there's a better method than the two. It's a full copper heatsink that's a bit old but it's still fine. I'm holding it together now with kapton tape but it's not being used in that state.

I hope you know what you're doing...

If you don't know what you're doing, it's best you find a replacement heatsink for, what looks to be, a laptop's cooling assembly off of Ebay.
