Intel OC Software

Intel has some hot overclocking software available for their boards. They call it "Intel Desktop Control Center"
http://www.intel.com/design/motherbd/software/dcc/download.htm

It gives you three performance options for your CPU speed. The first underclocks...in my case about 50MHz, the second runs stock, and the third overclocks....in my case about 90MHz

The software also allows for "custom" control of FSB, PCI, and PCIe clocks.
The FSB is adjustable from -2% to +4%
The PCIe varies incramentally from stock 100MHz to 107.92MHz
The PCI can be tweaked from oem 33MHz all the way up to 40MHz

Not exactly powerful software, but has more OC'ing potential than their BIOS does.

Here's my maximum OC of FSB +4%

As you can tell, D20L is hard at work

Yea, the 4% over is for burn in functionality.

90Mhz won't be really noticeable.

but 90mhz is still 90mhz more than you had before. Every little bit helps especially when crunching. Good find Sally. Now I wonder if they make a ClockGen for that board.

Yeah, I'm packing "heat" too.

I chose to keep my PCIx and PCI at stock speeds to avoid any possible issue on *major OC's, such as this.

76ºC hot? Nah. Its only making my power supply fan throttle up to speed...

and I thought my dually was hot at 54C pushing 4 D2OL clients! But its good to see you guys parting that netbusrt fury to good use.It should be interesting to see how you two compare. If some one to were want a hand one might be inclined to lend said hand.

It shouldn't be that hot.

Something is wrong.

Yeah, my 2.8C only runs 52-54 with D2OL and SWG running. 76c is WAY hot.

well these arent c chips

and my C doesnt go above 49 at full load....

^^^^this is very true that throttling will occur. It would be worth a DL of Throttlewatch to see if this is the case. If not then the temp that is being read by the software isnt actual temperature.
But if it is throttling this will hurt your D2OL output! This might be a call to get better cooling for those monsters.

I should get a little pan and make an omlet with this puppy.

Yeah, my airflow kinda stinks in this case at the moment. My front fant is almost butted up against a rack of hard drives (which get fairly warm anyway), so air doesn't flow too well there.

Then, one of my side fans that blows into the processor isn't doing much good the way the aftermarket cooler is setup.

And, my system temps are both up around 50+ which obviously means poor airflow.

Interesting enough, she doesn't throttle back any at these temps though.

I hope to make a few changes to the case when I upgrade around the end of the year. I plan on watercooling, and possibly going with a raid0 SATA2 drive setup (if the board has raid) which will eliminate the need for the hard drive rack.

I've played around with ThrottleWatch while removing my fan from the heatpipe, and in a few seconds, she begans to throttle down. So I am sure the program works. So, it is also very likely then that my thermal sensor is not very accurate. Or at least I hope so, as I believe that it should be throttling at over 70.

You could have some serious fun with that case and a Dremel.
But yes this is one cause of you higher than normal temperatures. I have a feeling that the software is reporting them higher than they actaully are as well. Hence the no throttling.

I would look into getting a 5-1/4" mount for one of your HDD's. Having them that close together is not good......you should have at least one empty bay between them. The combined heat from those will crank your case heat up, even with a fan blowing on them.......there's just not enough room for the fan to be actually doing anything. Increased case heat = increased CPU heat.

I have 1-80mm intake up front, 2-80mm on the side (top-intake; bottom-exhaust), 1-80mm exhaust in rear. All are quiet 3 speed Artic Cooling fans.

Of course, the cpu's heatpipe blows straith up with an 80mm, directly into the large 120mm thermally controlled fan of my power supply.
Other than the hard drives, it is pretty open and un-cluttered.

In theory, I could have decent airflow.

I guess you could always put the Intel cooler on....that'd probably help

^^^yep^^^

That lower one prolly doesn't need to be there at all. Maybe a 60mm will fit below that rear 80mm....But, like weaZ said, Dremmel that biotch....those perferations for the fans are pretty restrictive looking to me.

oh i see now....yeah good idea 2old...it might even be possible to move the rear fan up a bit....and fit another 80....or maybe two 40's?

Dremmeling is a good idea...but be careful for appearances...it can get ugly quickly......

and can you explain the CPU cooler a bit....or give me a link....i cant see how its working....

a little dremelling to the exhaust fan area and then switching both side fans to intakes should help alot on the thermals of the case. Another thing that might help as well is to move the fan on the heatpipe to the front side (if possible). Then you wouldnt be pushing hot air up into the psu, but rather towards the rear case fan that you just freed up but dremelling out all that restrictive metal.

I hope these pics help out a little.

First- here is a view of my side panel- top fan intake and bottom fan exhaust

I will see if simply unplugging the bottom fan will help any.

Now, here is my rear exhaust fan. There is some room below it, but really not enough to add anything other than a chopped up PCI blower fan.

Here is my cpu cooler: Scythe Kamakiri The page show some views of it and also shows its size in comparison to other common heatpipe coolers. It is not possible to rotate the cooler to blow heat out the rear. And as far as moving its fan position, it loses efficiency when jimmy rigged to blow laterally.

It looks like a decent design for a cpu cooler, imo. I'm going to shuffle my hard drives a bit to try to free up the front airflow and see what happens.
I will probably abstain from tearing into my case until I get a water setup in a few months. I honestly don't think squeezing a 60mm in the rear would change my situation much.

Perhaps sound-damping my case is insulating it far more than I thought.

Do I see dust on that sink Shock

Yes, that was dust. Damn you! You made me clean my computer.

Anyway, I took it all apart and cleaned everything. Now the fans, case, drives, etc are all dust free. I removed the the CPU and GPU heatsinks and washed them. And, while I had the motherboard out, I found I was able to remove and rotate the brackets. Now the heatpipe blow out the rear fan.

I also space my hard drives out as well.

Now, my temps are a bit lower.
