Shuriken and Asus P5N7A-VM

[kikkegek]

I have just assembled my HTPC. On my motherboard, Asus P5N7A-VM I have a Intel E8400 cooled by a Shuriken.

I have Qfan enabled, but after XP has started, the fan sits there not starting.

It does make a small repetitive movement, as if it want sto start, but just not does it.

It is connected to the 4-pin CPU-fan connector.

I have searched the web for info, but can not find any good information on this combination.

For OS I use TinyXP rev.09. a slim Xp version, but with complete driverpack and SP3 I believe.

please advise?

Hello kikkegek,

could you please try if the fan starts when it is connected directly to the PSU?

What happens when you disable Qfan?

I disabled Qfan in BIOS and in AsusProbe and then the fan runs at full speed. So the fan seems fine.

Do I still need to connect it to the PSU?

Then probably the Asus board doesn't supply enough voltage with QFAN activated to start up the fan.

Hello kikkegek,

actually Qfan seems to be buggy and does not give enough voltage to the fan - Oli is right. The only way you could do is using speedfan to regulate the fan.

thanks! I installed Speedfan 4.37 just yet. I now have fan control. Thank you.

something is trange though:
you report that the fan can be controlled from 600 - 2300 rpm
- when i drop below 50% in speedfan, the fan keeps spinning, but speedfan is no longer reporting a rpm. at 50% the fan is at about 1350 rpm.
- when I drop below 40% in speedfan, the fan stops spinning.
- is there a way to get full control from 600 - 2300?

I have now left the setting for controle of the fan from 0 - 100%? OK?
I have left the desired temp setting for my Intel E8400 at 40C? OK?
And I have let the warning-temp setting for my Intel E8400 at 55C? OK?

Hello kikkegek,

is the fan starting at 0%? I would say this is a bit risky...
About the 50% border, I can't give you any further information. Maybe your board is not able to read out fanspeeds below 50% of the Shuriken fan. I just don't know what the hell ASUS did with the speed read-out.

no, the fan starts when speedfan reaches 40%.
Then when speedfan reaches 50% it start reading the rpm's of the fan.

strange huh? And this is already QFAN-2. So it is supposed to be the "new" and improved version.

QFAN and fan alarm need to be revised by Asus ASAP.

I have the same results with my Shuriken and the p5n7a-vm
