My New Computer. Impressed with the O/c.

[Lordbob75]

Ok, thanks for the reassurance.
Things should get better when I move to California. And/or I get WaterCooling.

Even with water cooling the ambient temp greatly effects the idle temps because you are still trying to cool the rads with high ambient temps. You might try improving the case flow some although your temps are safe as is and fairly typical for an area with such a high ambient. It's been cool in Cali here on the coast, we have hardly hit the 70's yet, wait till July or August though it will get hotter but not Arizona hot.

Yeah, I do know that. It probably doesn't help that I have my computer in between my desk and nightstand, so it is like a cabinet, but open at the top...

~Lordbob

Is there any space at all between the side fan and the desk, or is it literally 'wedged' between the two?

A cabinet scenario would definitely have an impact as well.

The front 230mm fan does an okay job at cooling the HDD cage area, but it doesn't really push much cool air further than that.

How is your cooler currently orientated?

Horizontal (exhaust to rear) or vertical (exhaust towards top)

Exhausting straight out the top through the 230mm may net you a few extra degrees, but as already stated - you're still well within the 'safe' zone, so it's probably not worth the hassle of re-orientating/re-pasting etc.

 

[Lordbob75]

For all I know, it is pointing inwards! I will have to take a look.

It is not wedges, but there is only really about an inch gap. I know I am within the safe zones, so it only has to last about 3 more months.

~Lordbob

An inch doesn't invite much cool air in, but I think she'll make it another 3 months

What i have done is wrong, i have just read the thread over all 5 pages and then LOL'd when i saw how many people say its bad.

I'm glad i've posted, otherwise i'd been starting a thread "my cpu has died?"

Thanks

P.s. I';ll read the thread.

 

[smarteyeball]

We're glad you listened - not all do

Overclocking is part science, part art and part luck.

Hmmm...good thread, and good advice since Intel lists the max volts for an i7-930 as 1.375.

Anyways while reading this thread I ran across Lordbob's post about his high idle temps and thought I’d share my thoughts/experience with my i7-930's idle temps.

My setup is in an Antec P182 case, see system specs; my room temps are about 23 Celsius (75 Fahrenheit). I’m using a Noctua NH-C12P SE14 for my CPU cooler; my CPU is running at 3.52gig on 1.125 volts. QPI/Vtt 1.2volts.

With that my idle temps ran mid to high 40's, and no matter what I tried... voltage tweaks, replacing the Cooler, reseating/reorienting the cooler several times, trying different thermo pastes, AS5, Noctua's NT-H1 paste, and now Arctic Silver's MX-3 (which gives the lowest temps by 2 degrees) I still find myself in the mid 40's idle, low 70’s load.

In the end I’ve come to the conclusion that these are good temps considering these factors.

Now a couple of notes…

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.
However with this BIOS setting and the fact that the fan isn't variable, the fan’s speed increases to the 1200 range as the CPU temps climb as seen in these images….


This image shows no load on processor, CPU fan running a 900+RPM


This image shows a load on the processor, CPU fan running high 1180's RPM


CPU-Z reading with prime 95 full load.

Hmmm… Apparently the board does vary it’s voltage to the headers, even with the BIOS set to disable smart fan. Odd.

Core Temp and Real Temp show the same temp readings while Speedfan reads 15 degrees lower under idle and load speeds...



At any rate the bottom line is that I have a quiet system with good temps.

Thoughts/Opinions???

It could be BIOS / board specific as my board only varies 50rpm+/- or so with the equivalent settings disabled, regardless of load or temps when connected to the CPU and FAN headers.

TBH, I've never really relied on Speedfan for monitoring as I've never particularly trusted any of it's readings. (CPU temps, GPU temps, fan speeds, voltages etc)

Core/Real Temp + Everest + mobo + GPU-Z et al have always seemed to be closer in comparison compared to Speedfans 'reporting'.

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 .... http://www.sevenforums.com/hardware-devices/81169-experience-gigabyte-motherboards-2.html#post717247

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...

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...

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

 

[BCXtreme]

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!

 

[sygnus21]

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

 

[dood]

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.

Good luck to any/all OC'ers.

Ain't that the truth

 

[Lordbob75]

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.
