I've been having a sporadic problem on the following system, in which, all the fans STOP working! That is the CPU, AIO, and Chassis fans! I've experienced this while in games when I notice the frame rate drops. When I check the temp with HWiNFO64, the CPU is thermal throttling (85C). This condition is unacceptable
in a motherboard. Has anyone else had this experience with Asus?
- Asus ROG B450-I Gaming motherboard
- AMD 2700X processor
- G.Skill F4-3200C14D-16GFX memory kit
- Noctua NH-U12S SE-AM4 heatsink cooler (hooked up to CPU header)
- Noctua NF-F12 PWM (rear outflow chassis fan, hooked up to AIO header)
- Fractal Design Dynamic Series fans GP-12/GP-14 (front intake chassis fan)
- Fractal Design Nano S case (came with above 2 fans)
- EVGA SuperNOVA 750 G3 power supply
Now, I've noticed several threads on this topic (none here in overclocker.net), but none totally solve the problem.
The plausible cause appears to be the embedded controller ITE IT8665E. I'm wondering if it's true: software is polling too often (either AIDA64 or HWiNFO64) and causing the chip to shutdown the fans. Or overheat? I've seen that HWiNFO64 does have support to disable the WMI interface for some Asus motherboards.
- Added workaround for ASUS ROG STRIX B450/X470 boards with buggy WMI implementation.
I'm using v6.0 and it's still happening.
, is there something not supported on Asus B450-I Gaming Mobo?
The solution appears to stop running HWiNFO64 at Windows startup. And I guess MSI Afterburner as well which displays fans as well.
