Super Inconsistent CPU temperatures

PCvai30 · April 3, 2020

I'm a seventh grader and I just built my first PC a few months ago. My CPU is the AMD Ryzen 5 3600x, my aio cooler is the masterliquid ml 240l rgb, my motherboard is the gigabyte x570 gaming x, my case is the nzxt h510, my gpu is the founders edition rtx 2060 super, and my memory is a 2x16 kit of 3600 speed ddr4 g.skill ripjaws. I also have a 500 gb ssd and a 2tb hard drive. Right after I finished building my PC in November, I noticed that the temperatures exceeded 100 degrees Celsius while simply opening up Chrome, and sometimes even idling. Whenever I tried to game at medium settings and 1080p, the CPU would get so hot, the sytem would turn off to prevent further damage. I took it to a PC repair shop and they told me that the pump of my cooler was probably broken. As a result, I got a new cooler of the same model and it worked well for the first two weeks: 20 degrees celsius idle and 60 degrees celsius at max stress. Also, my gpu, hard drive, ssd, and memory are all always around 20 degrees Celsius. For the past 2 months, the CPU has been doing extremely well for 2 days and then throttles every day for the next 2 weeks. Also, I changed and reapplied my thermal paste two times. The thermal paste is certified too. I don't undestand why my Cpu or cooler is doing this. If anyone could help, that would be great. Thanks.

Sounds like you have another faulty pump that is getting air stuck in the pump or something else.

Time to RMA it. At this point I would just go air cooling. It might not be as aesthetically pleasing, but for that low power chip it should perform roughly the same with much less hassle.

Thanks for the idea! I have a wraith spire AMD cooler that came with the CPU ( the one with the bigger heatsink). Would it be okay to use that or should I get a noctua type of air cooler?

Aftermarket coolers may perform a little better or be a little quieter, but try the included cooler first as it's perfectly adequate for the 3600x.
