I am getting my Sandy Bridge motherboard replacement so I am wondering if I should get an aftermarket heatsink since I have to buy some thermal paste anyways. It is not overclocked (I don't know if I will do that someday or not) but do you recommend getting a better heatsink even if I am not having any issues now? I am just thinking since I have to spend $10 on paste, and since I need to open the case anways, if it is a good idea, or if the stock one is just fine.
