Well then you need to get the 260 more air or remove it from your setup.

will my system handle two 660s in sli, also how are the 260s in sli compared to my 660s performance

A single 660 would outperform (2) 260s by quite a bit. A GTX260 max wattage is 182W and a GTX660 is 140W. Therefore, you should be fine running (2) 660's in your system.

If you are trying to get your 260 to run cooler, I would suggest removing the cooler and cleaning off the factory paste on the GPU and putting on new paste. It could have dried out over time. I've seen this happen before. That or there is a lot of dust built up in the cooler. Use an air compressor and blow out the card really well.

I swear by IC Diamond paste (Innovation Cooling). It's a bit thick, but it will last a long time and transfers heat amazingly. Prior to using that I used Arctic Silver Céramique. It is also thick and will last a great while. I used to use Arctic Silver 5, but it is rather thin and found it can dry out after a year or less. I like paste that you set and forget.
