I'm looking for a SB water block for my MSI Z68A-GD65 (G3). I can't find any. Does the S1155 Z68 SB chip even need liquid cooling? Am I better off without SB block in my loop? I have a MIPS X58 NB chipset water block that I am thinking about putting on my MB. I just need to modify the stock MSI Z68A-GD65 (G3)(link to photo of the block). Just not sure if it is worth the effort. If the added cooling will substantially lower temps then i think it will be warranted. If he stock SB heatsink works perfectly fine then i don't think i will do it. What to do???
