Cpu fan test

#2 You probably won't like this much, but it's the way to methodically go about this: Clear CMOS. At least you don't have to open the PC for it, just turn it off and keep the Clear CMOS button on the rear I/O panel pressed for 5-10 seconds. Then adjust all settings again to your liking.If it still doesn't work afterwards, i'd be leaning towards a BIOS bug, but we'll see. #3 Thanks for your answer!I cleared CMOS and restarted the system. In BIOS I only disabled the built-in WiFi since I don't use it, and I also disabled the full screen boot logo. I then I rebooted again, started windows and did the same tests.By default the CPU fan controller was set to PWM with Smart Fan Mode enabled. This time the temperatures varied between 47 °C and 75°C (since the other fans has higher RPM by default). Basically the results were the same. The CPU fan show no significant change during the render.If this is a BIOS bug, how can I make MSI know they need to fix it? Can I report it somehow? bios_cpu_fan_setup.jpg 126 KB · Views: 3,155 AMD Ryzen 9 3950X Package (Node 0) Temperature.png 23.3 KB · Views: 360 Micro-Star International Co. Ltd.

If yes, there's still the remote possibility of the PWM control being broken on the CPU fan, i.e. try if a different PWM-controlled fan responds to CPU temperature changes.If not, it seems to be a BIOS bug. You should be able to contact MSI here: #5 In the first test, all of the fans were running Smart Fan Mode. They are all PWM fans and all behaved similarly to the CPU fan. (No response to CPU temperature changes.) In the second test, by default only the CPU fan was set to Smart Fan Mode, so naturally the other fans were running at fixed rates.When I was running BIOS 7C35vA3, the fan controller worked fine, so I don't think it's a PWM control issue, unless it happened to brake for all fans at the same time I updated BIOS...I'm assuming that the next step is to downgrade BIOS to verify that it works on 7C35vA3. Then I should be

Aug 5, 2012 822 25 19,010 #1 Hi all, just a quick question today.I ran prime95 torture test for around 10-15 minutes to test my cpu to make sure it wasn't causing my bluescreen issue, my cpu went from normal idle temp "about 35c" to 67c, I know that's a little high, the cpu tj max is supposed to be at 71c so I shut off the test before going further, but now I find that 5 ish hours after the test, after nothing but idle, my cpu is idling at 42c, whilst my gpu is sitting on 35cCan the torture test make this happen? Cn it raise idle temps n a cpu? Oct 18, 2009 1,945 6 20,965 #2 no, there may be other factors in play. #3 What's your CPU, and are you using a stock heatsink? Those temps seem normal for a torture test, especially if you're using a stock heatsink of any kind. But it's not going to keep the temps that high at idle, at least not for long. After a few minutes it should go down to your normal.Improving airflow in you case may help a bit as well Aug 5, 2012 822 25 19,010 #4 Amd phenom ii x4 3ghz 945, stock heat sink too, I've put 2 case fans in but they don't seem extremely good, then again the heat of my bedroom they nearly just suck hot air at the moment, I'm looking into lots of upgrades over the coming months, one of wich is better cooling, I've moved a fair few things around my case n the last few days to attempt to get better cooling, such as moving my hdds down to the bottom in order forums fan to be more effective up the top and over the gpu, my current gpu throws the air back into the case, so this maybe a possible cause, but it hasent done it before, I will be getting another gpu next week it's supposed to throw all hot air through the back of the pc instead of just in the pc. #5 On a hot day like today (atleast most of the US right now) with no Air conditioning I could see you pc temps taking some effect. On air you can never really go below ambient temperatures.Secondly I had a phenom ii 925, and opted on buying another heatsink due to the comparable heat that you are getting.As long as you have some way of sucking that air out (usually a back fan or two) the gpu shouldn't factor in that much. Aug 5, 2012 822 25 19,010 #6 I have a rear fan, but it actually sits right next to the cpu, so drags the air around it, I've never seen the gpu make an affect on the cpu temps before.It's just odd that it sits
