The case temp must either be incorrect, or an inaccurate representation of the actual temperature of the air around your heatsink.Originally Posted by Andy3536
Heat flows from hot to cold... it wouldn't be possible for your heatsink to cool the CPU to below the case temp if that case temp was an accurate reflection of the temperature around the CPU cooler's cooling fins. Or... maybe you have a big funnel that brings in air to the CPU cooler from outside the case?

I don't know where the temp moniter is on the mobo, but i have a arctic freezer 7 pro, and the corsair HX 520 is directly above it blowing on to it. So you've efectively got 2 fans blowing through the heatsink, and the PSU does pull it's air from outside, and all the time the pc is at idle that air will be cool.
If the case temp reading was taken at the bottom of the mobo above the GPU, mabee that could be giving an aver the top case temp reading? Just a thought.
The HX520 will be taking air in from the case, and blowing it out the back, not the other way around.
What version of the BIOS are you running? I found that my E6850 temps were ridiculously low until I flashed to the latest BIOS. Now it shows as at 26 idle, pushing up to 42 when under heavy load - this seems more realistic to me.
Asus P5B Deluxe/WiFi in case it matters.
I've just run my pc up as a test, it does take in from the back and blow down towards the hsf and extraction fan.
My other PC does aswell with a thermal take psu (but much louder)
The E6850 is a recent edition, when i checked gigabyte's website for compatibility it said compatible after bios version F4, as there was an F5 available i installed that one.
Probobly not much of a comparison with different manufactures of mobo.
I own one of these also, and I can assure you mine does not do the same. It should most definitely NOT suck air in through the hexagonal mesh and blow it out inside the case.
It makes no sense to blow hot power supply air on the CPU heatsink. The air should be sucked in by the big 12 cm fan on the square base of the PSU and be blown onto the aluminium heatsinks inside. The air then should make its way out of the back through the hexagonal mesh. If your HW 520 is not doing this, then the fan is on the wrong way around.
As further proof, see this page:

A direct quote from this is:
A single 120mm fan draws air into the power supply from below, blows it across the heatsinks, then out the low-impedance back grill. A wire grill protects the fan while providing a low resistance to the airflow.

But surly it would upset the internal airflow by taking air out the back of the spu, as it would draw airflow away from the CPU and the extraction fan.
Could it not be that it is designed to blow air towards the extraction fan?
So position the HSF to blow air at the PSU, or get a case which keeps the PSU in another compartment..
Why?
The piont i was trying to make is with the HSF blowing straight at the extraction fan, the air from the PSU will hit the HSF and get blown out the extraction fan.
Where as if the air was pulled in from above the HSF the airflow over the HSF would be limited, you would in effect have the extraction fan and the PSU pulling in different directions, which would seem silly.
No ..as the air passes through the psu it would get hot so then to push that hot air onto the hsf ...well it would not be good.
Go to the back of your case and hold a piece of thin paper to the mesh of the psu and it should be blown away from the case...expelled from inside.
But since the air infront of the hsf is cooler than the air coming out the back of it could it depend on where the system temp monitor is placed?
I think I will upgrade/flash the bios and then mod the case with a side case fan to blow onto the mobo. I would get TAC one of those flower pot looking things but the tower cooler is to big to allow me to fit it.
I sent an email of to gigabyte ... I hope they don't say it's fine as long as it's not over 50C ... I want a solution no one else seems to have the temps in this order ...lol ... except andy.

Just to clarify about my email by the way, they didn't say its fine as long as its not over 50. I just asked them if 50 was ok (because thats what mine once reached over the summer), and they actually said something like, "That motherboard has been tested up to as high as 90C and it was still functioning without errors"
Although, I'm talking about the gigabyte DS4-965p, so it may vary from motherboard to motherboard. But basically I was wondering if they where going to show concern about mine reaching 50C, and they didn't even blink.

Cool...err or not lol... if it's the same for this mobo that would be great especially if the rest of my temps are correct.
I upgraded the bios and now just upgrading easytune5 as it stopped working.
Thanks
OK did that .. the temp in the bios of the cpu is now at 26C ...that seems to be in the correct range.
Had to reinstall the old version of easytune 5 as pro had my cpu at 1.5ghz ... even though in bios it was 266x9...if I couldn't do that math I thought I should probably remove it

I got the email back from gigabyte and they told me to disable smart fan control in the bios...lol....the first thing I had done after building this machine was turn it off .... it was even in the email that it was off.
I had asked them about temperature zones and places where the system temp was monitored and that was all I got....great.
Yeah, that sort of reply from tech support guys really annoys me. They don't read your email, and they assume you're an idiot from the word go.
