Hey,
One of my friends has an issue regarding his CPU fan.
His motherboard is Gigabyte z77x-d3h

His GPU is a GTX 670 and is running at 30-35C (So the case is not the problem)
The problem is, the CPU fan is noisy as fuck. As in it runs at 100% constantly. It was starting to be noisy, so he decided to dust out his computer. Afterwards it became even more noisy.
I tried updating his BIOS and I think it actually started running even faster. (1600 - 1800RPM)
There is an option on all of my gigabyte boards in the BIOS to have the fan on max all of the time, maybe thats on.
Also the Gigabyte boards only support fan speed control with 4 pin pwm fans, are you sure that his CPU fan is not an aftermarket one with only a 3 pin fan?
It's a stock Intel one.
And yeah, told him to have a peek in BIOS settings. Might have to convince him :v:

Also, sorry. It's not at max speed. It's just [U]way [/U]higher than it should.
Yes you can manually alter the fan ramp, it might be a good idea just to reset everything to default.

Everything defaulted when we updated the BIOS anyways.
But actually, even though the CPU is loud. We may think it's the PSU.

Okay it almost 100% surely is the fan.
It's a pre-built (Twas before he met me) and he still has warranty. It's his third time sending it in lol.
Ivy Bridge processors have shit thermal paste between the heat spreader and the actual die, which can cause the fan to overspin (failure condition of not being able to cool properly.)
Looking at the wide range of temperatures on the cores, I'd go with the thermal paste under the heat spreader isn't applied properly. You can remove the IHS carefully with a flat razor scraper blade and put better thermal paste on it, but it'll void the warranty on the CPU.

Forgot to write PSU before fan. But yeah, it's both the PSU fan and the CPU fan.
Try to reset everything by removing the bios battery and psu power plug for a while and starting up in safe mode. (or just go to the bios screen)
Should have closed this. Sorry. Anyways, when he cleaned it out he apparantly hit some weird switch on the PSU that forces it to tornado. Problem solved. (Except when he puts in extra power then the screen starts with weird colors. but w/e
