I see you are using an aftermarket fan and heatsink, what happens when using the stock fan and heatsink? Is it same issue? For a stock fan Idle should be 900-2000 rpm’s
sry, but i bought an i5 661 tray cpu. the only fan i would be able to compare with is the box-fan of an i5 750. a friend of mine has got one. I suppose that the bios will be able to manage this one, but what about my scyhte-pwm-fans? do i have to test the one from the 750? is it compatible? it would not be a problem to test it, but i have to get it from the friend...
hi - I did test the intel boxed fan (DTC-DAA01/ 12V 0,6A Delta) from the i5-750. Surprisingly the effect with this original fan is the same// using the intel desktop utilities monitor I see it running at 1020 revs at idle and after starting "prime-test" it accelerates up to 1300 revs but immediately drops down to the 1020 idle state. I tried normal and agressive in the bios - using the fan detection on next boot. I am dissatisfied with the situation, because i have to run my cpu fan using an adapter at 12V at max revs.
I did try to downgrade to the older bios from january, but there's a problem using the "automatic windows program". so what can I do now? Is it a defect, or is it possible to fix the problem by bios update??
Please help me!!
- i got to deliver the system to my brother using it for scientific research and he's waiting for.
serial number: BTJG006001CZ
anybody outhere with an answer? please help me !!?
I have same issue with AC Alpine 11 Pro and had called Intel got no answer. Now,I had stripped control pin and let it spin in full speed .
hi - thx 4 posting! let's wait until intel support will find time to fix the problem!! fan control in my opinion is just a simple feature on such a board. perhaps there will be a bios update...
Hope never dies!
What Intel use is "iQST"--Intel Quiet System technology, it means if the system temperature (including processor) still within spec, then the fan will run at lowest to avoid fan noise
It is very easy to confirm if iQST is working or not, just use a pen to stop the fan, and let processor temperature go up to 10C (thermal margin), then let fan spin again, you can see the fan rpm in Intel Desktop Utility, it should be more than 2000rpm...
For more details about iQST, you can check the Technical Product Specification
I have the same issue with BIOS Version 0396. CPU idle temperature is around 60C however both CPU fan and case fan can only rotate at half speed. Upgraded to BIOS Version 0537 today. The fan control is no longer working and all the fans are rotating at full speeds and are very noisy. Windows 7 reports Intel Active Management Technology SOL cannot started.Tried to flash back to the old version but a failure was reported when flashing the management engine firmware! Come on Intel! Give us a working BIOS for this board!
Again, the FAN speed is not a problem because this is what iQst designed, but if you want to downgrade BIOS, please use recovery mode:
Remove BIOS jumper and copy BIOS file (.bin) to a USB disk or CD, then boot system with this USB disk or CD. This is the only way to downgrade ME firmware.
