I have Dell Optiplex 780 Mini Tower with a E8600 Core 2 Duo and I have ordered the Core 2 Quad Q9650 CPU, I have read I need the performance copper heatsink and I plan on ordering one next week, however will this heat sink from the Optiplex I have now work for now until I can order a new one? This is the stock heat sink I have right now https://www.ebay.com/itm/Dell-K2NV1-Optiplex-780-Heatsink-and-Shroud/132076986271?rt=nc&_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D2%26asc%3D52935%26meid%3D6f8b1196e3c4492a984e6a521036f139%26pid%3D100005%26rk%3D3%26rkt%3D12%26sd%3D232853075377%26itm%3D132076986271&_trksid=p2047675.c100005.m1851 I also have artic silver thermal paste. Would it be okay to use the stock heatsink until I can buy a new one?
