Sorry,i'am also not agree..i have here more then 100 chess engines and many off them stress the cpu more then Prime and these are my daily programs!!
My system has to be stable with my chess programs,no matter what other bench or stress program you use!
So,the only result that matters me is to see how good the Hydro H50 can handle my chess program!
And if it can give me much better temps (like -7°C from my max. now) then i will buy it.
