I recently replaced my 3900x with a 5900x. I have a Cerebus X with a Noctua 14s fan with two 140 fans, just added a 2nd one and didn’t change much. I have two 120s pulling air in from bottom, and one 92 exhaust out the back. 32gb memory, 650w power supply, rtx2060 6gb memory. MSI x570 Unify.
When stable, temps are 45-55, idle or light work. Oddly, when my backup software, EaseUs ToDo Backup, opens up temps jump to 80, fans go on high, then settle down. When backup starts, cpu utilization never goes over 15%. When I do work, with a cabinet design program (type of CAD program), which only uses cpu, not graphics, temps go all over the place, 60s, 70s, and 80 not uncommon. Fans all over the place. Cpu utilization never more than 20%.
I have played with fan curves, currently all fans are at 20%, 40%, 70% for temps reaching 30, 70, 80 degrees C.
I have played with PBO (which is off now) by reducing voltage by up to -.30, but got some blue screens and have not gone back to it.
Current temps and fans are annoying. As I write this temps were 47 then just spiked to 68 and back down to 50 right now.
What should I expect?
Should I be worried? Current behavior makes me nervous. Feel that machine will blow up!!
Is this case/cooling up to the task? (I love the case!)
How can I improve the behavior of this build?
I am just short of rebuilding the pc with a new larger case and using a Noctua 15 that I have from an older build.
Also, just recently, temps have been going over 80 yet my fans for some reason don’t spike. I have hwininfo64 open and they are hovering in the 500-700 range even with these temp spikes. If I reboot, fan behavior as described above resumes. I find this one troubling.
Do you have any recommendations or ideas about the above?
Thank you.
