We have not had any similar issues or reports so far but here are our recommendations:
-Test the system out of the chassis with the original stock fan that came with the processor you have.
-Clear the CMOS battery for 30 minutes and test again.
-Make sure you are populating all the fan headers.
-Update your motherboard BIOS to the latest version available:

Now here's a strange thing - I have done nothing to the PC (setup/config/BIOS etc).
I realised that the machine wasn't restarting itself (this was going to be another post: on shutdown, when the PC was fully shutdown & the leds on the motherboard went out, there was a momentary pause & it restarted. The only way I could shutdown was do hold the power switch in). This suddenly stopped happening.
And I realised that the PC booted straight through OK. I've just restarted the PC & (a) it stayed off and (b)it booted through to login....
How can solid state electronics be variable? Can the BIOS sort itself out?
Should I update the BIOS anyway?
I'll mark the question answered after a couple of days good behaviour from the PC.
Hi, it did the fan thing this morning after a couple of days booting straight through to login. After day 1 of it booting OK I reconnected the power on switch. I had been using the onboard switch having removed all the connections from the front panel header nearly from the outset, but it made no difference.
After reconnecting ONLY the power on switch, it worked OK yesterday, then today boot halted at the fan message.
So, going back to Dan's first reply, I'm going to have to remove this from the case - what a PITA. I also haven't got a stock fan. I could possibly borrow an i3 cooler, but is it really worth the immense hassle? How would my Arctic cpu cooler, which I can see working on boot, be a problem?
IRO populating all the headers, early on I tried hanging a fan off the aux but it didn't make any difference. I also don't want the noise of an extra fan if I can help it - my old 2004 dual xeon setup manage in the same case without one so this more modern one should be able to cope.
I am very keen to get resolution to my Intel problems, not least as I have 2 PCs not working properly or at all.
Now the cooler manufacturer is blaming the motherboard manufacturer: from Arctic Cooling
PC doesn't boot up
If the Computer doesn't boot there are several possibilities which could cause that
1) Your mainboard need a -5 volt signal
This currency isn't part of the ATX-standard since ATX 2.0. Some mainboards, specially older models still need it to boot up.
In this case please contact your dealer.
I am now contacting the motherboard manufacturer - is there a -5v signal I can use?
Our recommendations for this issue would be to use the original CPU fan just to test if you are able to boot.
I connected additional fans to my motherboard and I was able to see them on the BIOS, but I am using 4 pins cooling fans.
According to the TPS of your board on pag 56, all fan headers provide +5V only.
I'm sorry, thought I had posted up that I have been through the items suggested earlier. I removed the board from the case, I borrowed a stock fan from someone else's PC ) & I borrowed a V1 Arctic cooler fan. This has identified that for some reason or other, the V2 Arctic Freezer is the culprit. I have seen info on the web that suggest this cooler works on this board
I tried removing the CMOS battery - that was a trial in itself & despite being very careful, damaged the holder in the process). No effect.
Populated all the headers as before. No difference.
Updated BIOS. No difference.
Stock fan & earlier AC cooler. Booted OK with or without populated headers.
So that suggests that the fan is faulty & I am now in conversation with Arctic Cooling. who have replied (and helpfully - I'm relieved & pleasantly surprised).
BTW, I've also put the suspect fan in another new build with an Asus P8Z77-V LX and it boots OK absolutely straight out of the box.
Jonathan, if after replacing the fan with Arctic cooling you continue having the same behavior, feel free to contact your local support group for assistance: http://www.intel.com/p/en_US/support/contactsupport?group=processor
