A friend of mine would complain about his computer getting hot during winter. Doesn't make sense, does it? Well it turns out he had it standing next to a radiator. Starts snowing outside, the radiator goes on and the computer gets fed air that's probably something like 40C biggrin.gif

I should mention that I have another PC next to it, with the same case (SG13) and processor (i7-3770), but different motherboard. It has a Scythe Shuriken (not the big one).

And this one idles at 42c @ 900rpm, and goes up to 70c max load @ 1800rpm.

The Scythe Shuriken is supposed to be much inferior to the NH-L9x65 as well in theory.

PCs must not downclock or something guessing your voltage and clock speeds are constant. Thats quite hot for idle. Should be no more then a couple C over ambient.

So I just borrowed a NH-L12 to test. And the temps are still pretty much the same frown.gif And I triple checked to make sure all the screws are tight.

I'm convinced that there just isn't enough pressure of the processor. Maybe processor on this board (Intel DH67CF) is a fraction of a millimetre lower than others?

Or, however unlikely it is, the board isn't reporting the correct temp?

Good troubleshooting!

Both reasonable conclusions. But, that board is not even close to be the best of its generation. It officially supported 65w TDP Core i3 and Core i5 processors, not i7 models.

And there is this little tidbit in the Intel errata:
"Using the Intel® Desktop Board DH67CF with a 95W TDP Core and the supplied standard Intel thermal solution may not meet thermal requirements if used in a mini-ITX chassis. For specific processor compatibility, please visit http://processormatch.intel.com."

Could try a BIOS update. Or swap the cpu for an i3/i5. Or replace the board with a used Asus P8Z77-I. biggrin.gif

Lots of good thoughts and possible solutions, but I would like to rule out airflow air temp first.

Could you monitor the cooler intake air temp? Then we would know just how warm the air going into cooler is. If it's 5c or less above room ambient, then we've rolled out case airflow. But it may very well be 10-20c above room, and that is 5-15c hotter than it should be, and makes CPU 5-15C hotter as well. You might find "Ways to Better Cooling" link in my sig helpful. 1st post is index, click on topic to see it. 5th post is a good starting point. wink.gif

I've been testing with an open case and a 120mm Noctua blowing at it about 10cm away.

And yes I read many of your very well written posts yesterday.

@MicroCat

The i7 is only 77w and the BIOS is up to date.

I tried really hard to find an ITX 1155 board. You have no idea how hard it is nowadays frown.gif This Intel board is the best I could find, unless pay MORE than their brand new prices. I wish I had bought a load of ITX 1155 boards a few years ago as an investment biggrin.gif

The P8Z77-I has the VRM thingy that interferes with aftermarket coolers. Not a problem for the NH-L9x65 of course, but that's why I bought it in case I can find another board.

VRMs on P8Z77-I do not interfere with D14/D15, Genesis, Megahalems. I've used those on that little board. Just one-at-a-time tho.

If the monitored temps are pretty much the same from the stock cooler to the U12, have to assume the board is not reporting correctly. Or there's some freakish sensors in your 3770.

Are temps in the BIOS the same as reported in your monitoring program of choice?

The newly designed slide-on covers for the NH-U12S, NH-D15 and NH-D15S will come in three versions (all black, all white and black with interchangeable inlays in black, white, red, yellow, green, blue) that will allow users to colour-coordinate their heatsinks with all popular build colour schemes. All versions should be available before the end of the year.

Seems Noctua is trying to compete with Cryorig/Thermalright/Phanteks/be Quiet! more on the aesthetics front

also the 120mm A series fan appears to be very much like EK Vardar / Nidec Gentle Typhoon design
