Built a new pc last friday ran stress test to determine system stability. prime 95 max cpu temp was 57c. memtest64 8 passes no errors. unigine heaven max gpu temp 67c. Since I recently installed two new case fans i decided to stress test my pc one last time to see my temps and overall stability. I set prime95 to smallfft and furmark furry donut and ran both simultaneously for 20 minutes and my pc starts making this noise after like 5-10 minutes. max temps were, cpu 66c, gpu 71c. Take a look at the video and let me know what to do. please help.

Just take your finger and put it gently down on the blades until they stop for just a second or 2. If the noises go away, then replace your cpu cooler. If you are hearing like a squealing type sound like a fan, could be a bearing in your cpu cooler fan is going out. I've seen the fans on the evo go out. Good news is that any 120mm fan should fit your cooler.

In fact, your cooler should have come with extra fan brackets. Perfect time to get 2 fans and set up a push pull config on your evo for even better cooling.

i checked all fans everything seems to be good. Noise seems to come on when cpu fan hits 1650rpm and the cpu temp is at 54c, that is when i start to hear it and it gets louder as the cpu rpms and temp rises and settless down when temps get below 53 and rpm below 1650

just a few seconds will be fine. Like an engine in a car, you can get some garden hose (1/2 mtr dry) and listen at one end while the other goes next to parts suspected of the noise, helps zone in on the exact part at times, just don't hit the fans moving etc. does sound like a moving mechanical part though, likely a fan has seen it's day
