So, I've been running my Phenom II x4 965 @ 4.0GHz on 1.51 volts for a few months now. Until a couple days ago, I was idling around 35-36 degrees and maxing out at 54-55 with my CM H212+ cooler. Recently, I overclocked my 2 DDR3 RAM DIMMS from 1333 to 1600MHz, and to keep it stable I increased the voltage from 1.5 to 1.64. Right away, I noticed I was getting much higher temps, and it continued that way.
I reset the Memory speed and voltage, but I'm still getting higher temps. I reached as high as 58 degrees with playing Bad Company 2, and was idling around 40-45 instead of 35-40. I'm now running it @ 3.7GHz on 1.4 volts, but I'm still idling around 38-40. Something have definitely changed. I reseated the Heatsink with a new thermal paste application, cleaned my dust filters, and used condensed air to clean out the inside (there was almost no dust as is), but the temperatures didn't change at all. I'm pretty frustrated, as now I'm running my CPU slower and still getting higher temps than before.
With this info, is there anything I can do to reset temps back to normal? Could the sensors have become faulty?
If any more info is needed, I'll gladly comply.
Well I live in Texas so it's hot all year. The AC keeps the room at a constant forced 72 degrees F, and I don't think the change in seasons would account for a 5 degrees temperature increase within a day's time.
It is really interesting to find somebody, who is in the same situation like me. I didn't overclock CPU and didn't look at the CPU temperature, before I bought the memory. Therefore, I cannot tell, what was the original temperature of CPU. I also rose DRAM voltage to 1.64 Volts in order to rich reach 1600 MHz DRAM Frequency and receive the increase of maximum CPU temperature from 58 degrees to 64 degrees at 100% CPU loading with stock cooler.
