Everything installed great!

Even under load I was seeing temps around 72C. I highly recommend to just replace all 4 fans with the molex connector and call it the day if you decide to convert to some heatsinks. I bought my fans/molex fan connectors from the following fleabay links:

I did went the extra step of adding a drop of machine oil to the bearings, but this was just for the life of the fans. They appeared to be pretty well lubricated from the factory.

Best part was that it did not sound like a jet engine taking off. Fan noise is noticeable but not extremely loud. I will sacrifice some dB just to give these 2.7s some extra life.
