2FastCPU has just posted a review of the TI Dr Thermal TI-V77 HSF for your viewing pleasure. here's a snip:
"The Dr. Thermal TI-V77 heatsink from Thermal-Integration is a pretty massive cooler. Measuring in at 82x74x46mm, it certainly isn't for the weak at heart. One should also take in consideration that since this heatsink is wider than conventional heatsinks, you may have a problem of capacitors getting in the way. Make sure you have enough space before thinking about getting this cooler. Your alternative is to cut away a few of the fins, but this consumes precious time. Most people would not want to cut a fins out of their heatsink anyway."
