It probably won ' t work with totems . <| sep |> No matter or electromagnetic waves are to enter SCPXXXXB , for this reason XXXXB is composed of 6 metres of lead with layers of sensory equipment , vacuum pumps and signal blocking materials . SCPXXXXB is already buried so deeply that this much lead would be counterproductive . Cosmic rays would not be an issue at this depth , but radioactive Pb 205 is . A large volume of isotopically pure leadimpregnated concrete may be a better option . <| sep |> Some aftermarket coolers are quieter than stock ones and some aren ' t I don ' t know as I ' ve always used aftermarket ones for other reasons . I own the Hyper 212 X newer version of the 212 Evo and it ' s pretty quiet quieter than the cheapo cooler I had on my old PC but again I don ' t have much to compare to . From a cooling standpoint the aftermarket ones are better unless you buy a really nasty one the 212 Evo is a good choice . But as the i 7 6700 can ' t be overclocked you probably won ' t need an aftermarket cooler . If you get a 6700 k or i 5 6600 k then you will need an aftermarket cooler . If you buy an aftermarket one now you will be able to reuse it in the future if you get a new CPU that you want to overclock but idk if it ' s worth it when you could just one then when you need it .
