990FXA - UD3 Rev 4

[AgentFXA]

The CPU fan speed stays ~180 rpm (212 EVO) after system is coming back from sleep/hibernation - the only fix is rebooting the system to get the fan rpms back to ~900+ (idle).

I've seen the problem with F2/F3i bios as well as with a rev3 board (FC).

I guess it's a bios fault or maybe the cpu fan need replacement?

ideas anyone?

You are running windows 8 right. Some of the boards have updates to fix it and other boards don"t To they have a fix all I can say is never let it go to sleep sorry. Plus I know that isn't the fix you were looking for.

But the other thing some of the boards are getting to the point too that they might not do a bios update. Here is link to some body else having the problem and they haven't got a fix on the their AMD board yet.

Nope, using Win7 here - pretty sure it's a bios issue.
Have read the other thread and sounds very similar..

Thru windows make it where hard drive never sleeps. Doesn't take much power and it usually solves it.

I guess you mean disabling system hibernation to prevent this issue - yes, I could do that but electricity is expensive in my country and point is such simple things should be fixed by the manufacturer... it's a simple bios update I am sure.

Gigabyte support suggested me to test with another cpu fan, MEH, I've already done that before opening the ticket - same problem!

I have similar problems after Sleep:
After sleep, the cpu temperature sensor malfunctions. Tested with AIDA64 (-128ºC) and EasyTune6 (100ºC) see fig

I use watercooling , so i do not use the CPU fan
The revolutions of the system cooler 1 down, but little
In my case, this problem did not occur with the bios F2.

I also have a very similar problem with my ga-990FXA-UD3 Rev 4 - after waking the PC, any processing intensive task results in a rapid rise in the cpu temperature and a crash if immediate action is not taken. Instead of speeding up, the CPU fan does not speed up or even stops. There seems to be a major problem with the F3i bios.

Please.
We should to write to Technical Support of Gigabyte.
The problem is serious.

The thing is that when you think the computer is in sleep the computer is still drawing power. Even if you shutdown the computer. It is still drawing power.

The only real way to save power is shut the computer down and switch off the switch on the back of the computer or a power strip. All computer still draw power in sleep or shutdown.

The power consumed in Standby is considerably less than that required for its normal operation. Aside from this, setting the computer to sleep after a period of time should avoid the situation where it inadvertently gets left on for long periods of time.

In any case this is an insidious bug in that it results in temperature cycling of the cpu which is likely to degrade its life. Furthermore it can be difficult to diagnose since a computer affected by it can be checked after boot-up and appear to behave in a completely normal way.

I've reported the issue to Gigabyte - I expect that they should act on it promptly.

The power consumed in Standby is considerably less....

I've just checked this here - power usage:

http://pbrd.co/1x9EElj

off: 5W
sleep: 18W
idle: 130W
load: 270W

and it is just 1 GPU in my box

Use a SSD and that solves that. Then you can keep hard drive on and still use less power

power consumption is not really the topic of this thread 
.. fixing the CPU fan speed after sys wakeup is!

No one has answered of the gigabyte technical support?

The advice was to go back to the F2 bios. I'm a bit surprised that the F3i bios is still shown on the download page - in my experience it was completely unacceptable. My problem might have been a windows 8.1 thing, but that would still be bad enough.

If anyone else has run into similar problems, make sure you report them to Gigabyte.

There was an F3h bios that didn't seem to get wide distribution. Does anyone know if it had issues?
