I got some nice heat sinks on my CPU and most importantly on my P45 NB check it out I love my thermalright HR-05/SLI/IFX NB cooler. It never gets hot!!! This one might help you because if you go and look at it.....well it's shaped sort of like an L. I curves down about 2 inches and then bends up. Which might work to fit around your other heat sinks. Check it out I think it might actually be able to help you! Here is a website devoted to heat sinks.... http://www.heatsinkfactory.com/thermalright-mf-23.html I also posted a link to Thermalright...... and a pic of the heat sink........http://www.thermalright.com/index.html..... and......http://www.thermalright.com/new_a_page/download_images/booklet/hr05_ifx_sli/part1.pdf Hope this helps!!!
