I have a i7 4770K @ 3.5 stock settings with a cool master TX-3. When I first got this CPU a few months ago, I ran prime95, using HWmonitor and the TDP never went over 85w. Temps stayed below 65c. The other day, I ran prime95 again and noticed temps are higher than before and TDP wattage is 102 w, which is over the max 84w TDP for this CPU. Everything is stock. All settings same as first tests a few months ago.

1. What could be the cause of high spike in wattage?

2. Is the CPU bad or could it be a motherboard or PSU problem?

3. How can I fix this problem?

Thank you.

Hey there! I wouldn't be concerned about this in the slightest bit. Your CPU appears to be drawing that 102 watts at a time that it is probably really under load. Your CPU has a thing called Turbo Boost Technology that boost your CPU Core up to 3.9 Ghz when your CPU is under a load. During this time your CPU may ask for more power to get you to that frequency. Also if you have the Intel Integrated Graphics, this would also be expected if your CPU doesn't have the Turbo Boost Technology. You could be in the mists of doing something really graphic intensive and your CPU is needing more power to be able to run its self and the graphic processor.

Unless your CPU gets up to around 125 watts...I wouldn't really worry about it. At that point...I would be questioning whether your motherboard has some sorta overclocking function in affect. You could explore that option as well if you're really concerned about it. At the very first few seconds of start-up...you should see an option to press F2 or Delete, hit either of those keys...maybe 3 or 4 times within a 2 seconds of each other (I have to do that) to make sure you get into the BIOS. Before you change any setting at all...make sure you know what your changing and the possible consequences of changing the setting or value are.

Hope this helps :) .
