I have a problem with a warning popping up saying "You CPU fan doesn't work properly. You must turn off your system right now and check it!". The thing is, I only run Crimson and HWinfo (so no conflicting monitor software). I also have ignored the low limit in BIOS fan monitoring (formula-z board). I read this thread and it references me (next to last post) to a solution/option that I cannot find in the Overdrive settings of Crimson.
What do I do? This message pops up all the time. When I've been away for a while, there are plenty of them. The CPU temp is now 43(c) and RPM is steady at 1020-1030 RPM. When I play The Division I also note that the CPU temp never goes about 60-65 and that the RPM is following up and it's working fine.
CPU: AMD 9370 4.4 Ghz eight core
GPU: Saphire Radeon R9 380 Nitro (stock fans)
Case: Cooler Master Storm Stryker
CPU Fan: Cooler Master V8 GTS (PWM)
Front fans: 2*Nanoxia Deep Silence 120mm PWM Ultra-Quiet PC Fan, 650-1500 RPM
Top fan: Aerocool Silent Master - Red LED - 200mm
Bottom fan: Stock Cooler Master Storm Stryker 200mm fan
Back fan: Stock Cooler Master Storm Stryker 240mm fan
Edited to update post with PC specs (fan and temp related).
If that is the core temperature, the CPU should never get over 61*C if you have an FX-8000 series, and the fan should be spinning at at least 1500rpm at 55*C. So I would say that no, the CPU fan is not working properly, make sure it is not limited in BIOS and your case has proper airflow.
Sorry, should have mentioned that I don't use the default CPU cooler. I updated the original post with my specs.
I did turn off the control in bios, and it's at a constant ~1580 RPM now. TMP is now at 41(c) so only one degree difference. The 10(db) difference is not worth it and I really don't see the point for regular use. While using the BIOS/Mobo controller the fan speed still increases when gaming and the temp is max 65 degrees. And from your last sentence, I read it as you men that if i use BIOS/Mobo limits, the fan is not working properly, because of it? A strange thing to say. It's a PWM fan (but you couldn't have known).
