I have an Intel Core 2 Q6700 and it fits the Core 2 just fine, so will it fit an i5 3750k? I'm not sure of the name of the cooler, but it fits an Intel Core 2. Edit- Oh, and this might be wrong forum or section, so point somewhere different if it is. Edit 2- It is the Zalman 9700 I think? The one optimized for Nforce boards and LGA 775.
