not so for me. 4.8 ht i require offset of .085 iirc and no ht i can run .055offset. for 5.2ghz(max benched ive done) i needed like .060 less for no ht. he didnt say it would kill it if you had a water cooling. he said it could if temps go really high. but voltage doesnt kill CPUs , it only degrades them and the cpu will shut down far before it gets to the point of damaging itself usually.. Amperage is what would kill a CPU, so maybe hes talking about drawing too much amps through the CPU, not sure.
