I use "Industrial Grade RTV Silicone Sealant" at work to seal gutters and what not. Works great for sealing up my water blocks. If you use screwes to tighten the top down the stuff makes an awsome glue aswell. You really have to beat on it to get the top back off. RTV basically means it can withstand high temperatures. The stuff I use can handle up to 500F. Regular silicone sealant isn't made to handle the higher heat ranges.

Both are silicone based, but RTV stuff adds "iron-oxide" for the extra temp resistance. Regular silicone sealant does not have that.
