Haven't try so much, cause my GPU doesn't come yet, I use from my other computer few hours, in those hours the machine work great, good FPS on games, good speed using custom programs, I try some stress test, the fans speed read show some crazy numbers but is for the BIOS mode that came pre-installed on the motherboard, but the seller told me that, but the seller says that the temperature reads are real, in that case the temperatures doesn't surpass the 60 celsius, I don't have a temperature pistol but touching the metal is not hot and also the exhaust air isn't warm so the reads can be truth, in any moment the machine freeze or collapse during the stress test, the OC only forces the high frequencys on work, when the computer is idling or using some light program the clock speed is low, so is good that is not locket for the power consumption, maybe later will give more data, is a computer that I will give for present to my cousin so will not use it to much. The seller is nice by the way
item shipped faultlessly as described runs all my games fine :D
