prime 95 is werid!

[KK_Disco]

ran dual prime today and first couple of minutes it was fine but then all of a sudden my temp started to drop so i thought there might be an error message on prime. checked and nothing happened. set one of the prime memory use to 400 and the other one to 52. thought its weird so i checked window manger and found out that its only using 1% of the CPU. its really weird. did i do something wrong? use blend torture too. usually my temp just stay high till i end the test. this happened twice. wonder what happened
