I recently played a graphically intensive game for the first time in a couple of weeks and after about 5-6hrs of playing, the computer became very loud most likely because of increasing fan speed. Now, this is the first time such a thing has happened and I have played more graphically intensive games in the past for just as long a period with no issue. After playing the game and closing it, the computer remains very loud. It remains loud after I restart and after shutting down for the night and logging on in the morning. I opened up my case to try and isolate the noise but was unsuccessful. I read that it's possibly either the CPU fan or the power supply fan. I downloaded a CPU temp program and determined that my processor cores (2 of them) are at roughly 50C on idle. They go up to 55-60C on full operation. I use a stock HSF. At this point, I tried to also download a fan speed regulator program but was unsuccessful. What should I do to lower the fan speed or fix this noise issue? It's very loud.
