OT, when did you upgrade? I must have missed it - the last I remember you were considering it

(kudos btw)

May. And yeah I’m loving the new system. This is the post where I got it setup .... Experience with Gigabyte motherboards?

I double-checked the BIOS and found that I do/did in fact have Smart Fan enabled. Still, it's curious that the fan would vary that much considering it's a non-variable fan.

Seems to me Gigabyte has the board setup to have the CPU fan header setup to vary its current based on temps when Smart Fan is enabled, regardless of whether you use a 3 or 4-pin fan. That’s too large a variable to think otherwise.

At any rate it’s not an issue as far as I’m concerned, just something I never expected.

Here's the cooler...

Have something of substance to add or are we just adding to our post count???

Sorry! Just thought that was really funny!

I'll add that I agree mid-40s idling isn't too bad. I have a system I'm working on that idles in mid-50s, so ... yeah. Glad you can achieve both good temps and low noise though ... I was never able to do that with custom components.

Perhaps reading this would enlighten your funny bone...

The NF-P14 fan that comes with the cooler is a 140mm 3 pin fan so it should be running at a constant 1200RPM’s +/-10 percent, however Speedfan, Everest, and my motherboard’s (GA-X58A-UD5) BIOS all state the fan is running at 900ish without a load. What’s more interesting is that I have "CPU Smart Fan Control" disabled my BIOS so the board should give full voltage to the fan headers.

BTW I am aware that all fans are variable if attached to a power source, like a pontentiometer, or a PWM source, such as those employed on most motherboards for the CPU header

At any rate I am happy with the temps I have considering my room temp is currently 80F/26C

The room in which the mid-50s machine is running has a room temp of about 76F. According to our flags, we're from the same state, so you know how hot it's been? Well, the air conditioner vent blows ice air on this machine (and on its user ... brrr) all day and all night, but still can't get the temps below 50C.

So yeah, 40C idling with a room temp of 80F is GREAT!

The central air unit we have doesn't cool all rooms adequately. While my living room feels like Antarctica, our back bedrooms feel like the Sahara desert. You could say we have two climate zones here

Unfortunately we can’t vary the vents because of the fire suppression system that requires all vents be open at all times, so we have the non-variable type…. There goes that word again :)

40C is acceptable....at least from my experience in the C2D world. (Havent moved up to an i(x) chip yet..)

I found this thread a bit of hoot...and am glad to see others stepping up to keep this new OC'er from nuking his machine(or burning down his house.)

OC'in can take some time if you want something really stable.
It took me nearly a week (Probably about 15+ hours of debating, setting and testing) to get stable with my E8600.

I too found the magical 4.5Ghz goal a bit elusive(on an E8600 of course). I could get there, but long term stability was a problem.
I finally settled for a rock solid 4.2Ghz. And this is all on air (See my specs)

The voltage above is acceptable. A bit of sweet spot for what its doing...

Bragging rights is one thing. We see it all the time.
But you want something SOLID that you can depend on.
My setup I've described? Its been running 24x7 for over a YEAR only having to be powered off for an occasional case cleaning or neighborhood power outage.

Good luck to any/all OC'ers.
It takes time and patience to get it right.

Sorry I missed it, but a belated congrats any way :)

As for the variance, it's actually not that odd when you think about it.

Those fans will run between 700-900 RPM with the LN/ULN adapters if used - having the cooling option enabled in the BIOS is essentially doing the same job as the voltage adapters, hence the variance.

Ain't that the truth

Sygnus, since computer fans operate from 5v to 12V, they will run on any voltage between the two.

Regardless if the fan is "variable" or not, you can vary the speed simply by changing the voltage. Which is exactly what the motherboard smart fan does.
