I just picked up a 939 board and processor. The processor was free, the board wasn't -- got it on ebay.
I just put it all together and it's sitting on my desk and I'm wondering about the setup.
The chip is a X2 4400+ Toledo with a JH-E6 revision.
I was running OCCT and my core temps went from ~30C at idle to 50-55C under load, despite the fact that I have a TT Big Typhoon. I know this thing pushes 110W, are these temps normal?
I've mainly seen Thermalright coolers on DFI 939 setups -- has anyone had experience with a Big Typhoon? Putting the backing on the underside of the mobo meant covering part of the components with the insulator. I'm thinking I need to cut the backing off and reapply with a gap in it to promote heat dissipation.

Thanks!
How much VCore are you running?
Is the setup overclocked?
What are the ambient temperatures?
How much TIM did you use?
Do you know what the X2 4400+'s stepping code is? The reason I ask is that some of the last Toledos (CPUs from the LCB9E/LCBQE) have been observed to "read hot," i.e., their thermal diodes to register hotter-than-expected temperatures.
Any of these, singly or combination with each other, can raise temperatures.

The VCore is 1.33
This thing isn't oc'ed, it's running at stock.
The ambient air temp is probably in the high 60s.
The stepping is 2.
I just used a little dot of AS5, maybe 1/8" in diameter.
The stepping code I referred to is not what CPU-Z reports; it's a number that's printed on the CPU's IHS. You'll have to remove the HSF to have a look at it.
It will look like this:
LCB9E 0704TPMW or CCBWE 0546XPMW.
For what it's worth, it looks like the chip either runs hot or reads hot. I wish I had your ambient temperatures in my bedroom, and the VCore and the CPU speed are stock.
I'd reseat the Big Typhoon and see if you can get better temperatures.
Question: Which Big Typhoon is it? The VX, or the original version (which has the superior bolt-down mounting mechanism)? Also, what fan is mounted on the heatsink?
I had one of these board. EXCELLENT BOARD by the way! The only complaint I had with it was the temperature reporting on it was off. Mine wasn't far off the mark, but some people were reporting up to 15C increases of temperatures over what was really the true temps. This was on the old DFI-Street forums, which are gone now, so sorry, I don't have a link for you. However, you may be interested to know that there is a bios update on the dfi site which adds temperature level adjustment in the bios by 1 degree increments.
Thanks for the info. The code is CCBWE 0608GPGW. I took the cooler (the regular typhoon (PL-0114), not the VX) off and the AS5 spread was approximately 1" diameter just slightly offset from center. I'll reseat and check it again.

Any other thoughts?
slngsht's comments are interesting (see the post above yours). I didn't know that the SLI-DR Expert read hot. My only comment on that point, though, is that how wise would it be to adjust or offset the temp readouts if you don't know what the point of reference really is?
I would experiment with TIM application and tighten down that Big Typhoon as much as possible.
lots of people would get a laser temp probe and read the idle temps and compare them to the reported temps in pc health status in bios and adjust the temperatures accordingly to what the probe reported. seemed to work well, although it was hard to do with the heatsink on. I personally pulled the heatsink for a split second to see what was reported. I was very nervous doing that though.

slngsht, how expensive is a laser temp probe? And where might I get one?
Considering the typhoon is about $45 @ the egg, I was hoping for much cooler temps. I'll fiddle with the heatsink and cooler. My other concern is the cluster of components on the back side of the board underneath CPU. The insulator and adhesive backing are stuck right to it. I don't think it can help any...
I've always been happy with my Big Typhoons. In fact, my current sig rig had one mounted on it; with far worse ambient temps and overclocked dual-core Opteron, my temps are better than yours are. Of course, I've got no IHS on the Opteron, but nevertheless the point I'm trying to make is that the Big Typhoon is a very good cooler for your CPU, in my opinion.
Something else other than the heatsink is the reason for your higher temps than expected...
Focusing just on the hardware side of things, I'm inclined to think that perhaps the junction between the core die and the interior of your CPU's IHS may not be optimal.
You may be right. My brother told me that one of the two cpus he gave me came from a number of fried boards. Could have been PSU, or something else, but who knows. If it's the chip, I'm hoping the typhoon can help cool it down.

Thanks.
wow, i'm going to have to look that up. From what I've seen is that they can run anywhere from $40 to $200. They're pretty fun too, you can get the temperature of the top of your car at 50' LOL

I think your analysis is correct. OCCT shuts down after 15 minutes. In PC Wizard CPU temp reached 45C, and the cores made it to 56C & 52C. Is there a way to pull the top off this thing???
I just put in the 3200 single core Venice (LBBLE 0543XPMW) and its core is running @28C with the CPU at 43.
I'm scrubbing the mating surface with 91% isopropanol each time til there's no residue on the cotton swabs.
Guess I'll overclock the Venice to start with. Anyone have some 4000+ DDR ram?
You can take the lid off of S939 chips, yes. It just takes some nerves, some knowledge of how deep the cuts should be, a steady hand, and some patience.
(If I wasn't in a hurry, I'd link you to a couple of online guides on how to do it. But there are PLENTY of resources available online on taking the IHS off of a S939 chip.)
(My sig rig's CPU has its top off.
)
Once it's done, I also recommend you take the extra step and cover up the delicate little ICs lining the periphery of the naked die. I used black electrical tape to do the job.
I've attached some pictures to illustrate the point.
Check the base of the TTBT with a razor blade to make sure it is flat. I have the VX on my 6750 and at first my temps were a little higher than I wanted, I checked and sure enough it was not flat.
A little sandpaper later and it is GREAT! 4hrs of OCCT max 40c @ 3.6Ghz

Nice job! I didn't have the nuts to uncap my opteron.

I'm definitely going to lap this thing, but I will say my temps today are about six degrees cooler than yesterday -- that's with the ambient air temps probably up 2-3 degrees C. All of this in spite of a 20% overclock (2.0 bumped to 2.4 -- and I'm pushing for more after this reply). Go figure.
