These bars have a low profile (thanks to their low voltage 1.5v) compared to Gskill Ripjaws such a big CPU cooler will not interfere with them and they will heat less and / or allow a higher OC. Strips are stable and have spent a Windows memory test without worries.
And what is so much memory? A nothing today to the game or office, but for some intensive applications (video work or image) I use it with a Ram Disk, virtual hard disk into RAM, and it's going much more quickly that SSD. I definitely recommend, provided you hit them right price of course!
