Zipang - Fan Problems

[shailesh1]

Hi

I have a Scythe Zipang on an Asus P5Q motherboard with a Q9300 quad core CPU. Recently, I noticed I was getting the CPU Fan Error Press F1 to continue error everytime I rebooted. I replaced the CMOS battery at first to see if that helped but it did not.

I then took off the PC cover to check the fan and I could see it was not spinning. It does spin if I manually force it to spin by pushing the fans but this means keeping the cover off.

Using speedfan shows the CPU RPM's as 0 if I don't start it manually with the temp at 60C. When I do start it manually, the RPM's rarely go over over 300.

I'm not sure what to do, can anyone help please?

1. Basically: Asus has much too low speed limits concerning fan warning. You can find many posts concerning this issue using the board search.

2. Anyway your fan should start with even low rpm at an earlier stage. Set the QFAN in BIOS for the CPU fan to MEDIUM or NORMAL (instead of SILENT) and also try PERFORMANCE. See which rpm values you can reach.

For me it seems as if your fan is faulty. You should reach above 450 up to 1000 rpm when using PERFORMANCE PWM setting (= QFAN).

As an alternative you can set QFAN to disabled - the fan on Zipang should run at full power (12V) with this setting reaching about 1000 rpm (+/- 10%).

If your fan doesn't reach this value when QFAN is set OFF you should start a support request.

Thanks. I have set the QFAN to turbo in the bios and the fan doesn't start.

I will now try and disable it to se if there is any change.

I also disable the fan warning as it was annoying me. Should I turn it back on?

It will continue to annoy you anyway. Even 500 rpm aren't enough for most Asus boards.

As I already said: if you don't reach 1000 rpm with QFAN disabled you'll need a fan replacement. Until you got this replacement I'd leave QFAN off to ensure 12V for the fan and switch the warning off (ignore).

OK, I've disabled the QFAN and I've just started speedfan. The RPM is registering as 0. Do I have to wait for a certain amount of time before the RPM speeds up?

No it has to spin up immediately when 12V are applied to the fan. So I'd guess the fan is faulty.

Hi there

I've received a replacement fan from you guys, thank you very much for that. However, I am now having a similar problem with this new fan. I cannot get the fan speed over 439 RPM and it is causing my CPU to overheat.

I have tried all the same suggestions on this thread again but cannot get the RPM's back up to 1000. Hope you can help again. Thanks.
