The 65c rule for the C2D's was set with the chips that had a Tjunction (the temperature where they start clocking down due to overheating) of 85c. Newer chips, especially the Q6600's, have a Tjunction of 100c. For those I'd argue that 75c is fine(some 25c below the throttle threshold), but I'd also call that a hard rule, if you're breaking 75c at all you need to back down.
He should use Small FFTs for testing his CPU, and Memtest for testing his memory.
The only reason to use blend is if you're too lazy to use Memtest and do a proper test of your memory.
Also, 65C as reported during these stress tests is not bad. I have pushed mine up to 70C, but I tend to get failures if the temp rises into the mid-70s. Not sure if it's a temp thing or if I'm just pushing too hard. In any case, I would suggest pushing the voltage up a tad and seeing what you can get out of it under 70C. You might be able to get 3.4.
A better cooler would probably allow you to push a little harder, but it's up to you if it's worth it or not.
The temperature sounds wired to me, I use Arctic Freezer myself, running my c2d at 3. Under load speedfan shows about 50. I think Q6600 is about 50% more heat so this temperature is fishy. Maybe if OP has a Tuniq//Ultra 120 but even those can't keep temp at 55 loaded when the Q6600 OCed to 3.2+.

Toms Hardware C2D Temperature Guide
Applying the same definitions to consult the Intel Q6600 G0 thermal specification should make this worth the read.
I am SOOOOO tempted to go get the G0 . . NOW. My B3 seems to be capable of 3.25 Ghz and FSB 1,440 Mhz. that's with a voltage of around 1.4125 or 1.42V. My coretemp values are (at 76F current room-ambient +-0.1F) at 63C for Core 0 -- the hottest of the four. But I've made some "cooling enhancements" for an air-cooled rig.
While the Guide and the specs say that the TCase value is the one relevant to throttling, I still want to keep the temps down. But if each TJunction temperature is below 65C and taken from a sensor embedded in each core, and if the thermal threshold for TCase is 63 or more, you still wouldn't worry about the silicon-to-metal interfaces on the processor. A 65C TJunction (core) value means a TCase of around 50C -- unless I've misread the "Guide."

You're probably right . . . . still:

And:
[Tom Cruise, "Top-Gun"] "Do you feel . . . the need . . . . for speed?!"
But let's face it. I took this sucker up to around 2.71 Ghz at multiplier 7 and the CPU_FSB at 387 Mhz so far. I had to loosen the latencies to 4-4-4-10, but according to other sources, they're good at that speed tightened to 3-4-4-10. Even so, it's hard for me thinking it was just my imagination that 4-3-4-8 at 375 to 380-something wasn't "faster." The "G-O . . GO" on Orthos just seemed to fly back and forth smoother -- faster.
At 3.24 Ghz and 360 CPU_FSB, that same visual effect seems a little sluggish. There are all sorts of facets to this business, and CPU speed is only one of them. Whatever anyone says about "synthetic" benchmarks, I'd pay more attention to the resulting numbers than to what my eyesight suggests . . . .
Also, I think I've noticed something, but I can't tell precisely what it means. I've loaded up Everest Ultimate instead of CoreTemp -- having convinced myself that the core temperatures reported between the programs are identical but for variation due to different times at which the periodic sampling occurs.
The reason I did that was to get a read on the TCase sensor. My TCase has spiked up to 57C upon occasion, while the hottest core maximum might be 65C. This was, of course, at a somewhat sweaty room-ambient of between 77 and 78F. [I choose to read the ambients in Fahrenheit, and the system temperatures in Celsius.]
Now, this is a difference of about 8C degrees -- not 15C [or Kelvin] degrees, as the C2D Guide suggests it would be. But then, this is a Core-2-Quad, which supercedes the C2D Guide. I suppose I should go back to the Intel web-site and see if I can find the spec for TCase and TJunction spread on the C2Q. If they have published one, that is . . .
Even so, if TCase is momentarily 57C at a room-ambient prompting most people to run to the household thermostat and pump up the AC, you're right -- nothing wrong with the temperatures.

re: been running 4 orthos simoltaneously for about 2 hours now.
is this the way to stress 4 cores?
Orthos is dual(or multi?) core only, no single core orthos made?
I can releave stress on Prime95/Orthos by playing mp3s...you maybe can do the same with 2 instances of orthos

use the newest version of prime as someone suggested or...
2 orthos since they only support dualcore
ok so i massively stress tested (using the newer one). 3.2 is rocksolid
now i have a few questions:
im doing 8x400....what EXACTLY is the difference between this and 9x355? (heat/volt/anything at all/overclocking capability increase or decrease).
my gpu is at 626/920 or so...is there a definite guide to stress test it? the ntune one is a joke and a half. doesnt even get my gpu past 60 degrees.
i play nfs: MW with everything max and res at highest, with the AA at about 50%. its so freaken nice. if i ult tab in between my gpu temp is at around 65. (still rocksolid. played obliv for an hour too everything is peachy).
finally: coretemp makes my comp restart andits really REALLY annoying. any ideas?

is there a newer version than .95? I'm using coretemp .95 and I am looking right now at 18c on both cores in a room with 23c ambient. Tjunction is reported at 85c.

try rivatuner or even atitool for gpu. atitool took my gpu to failure during stress testing then backed it off to the highest stable oc. try speedfan,tat,coretemeter, or even your mobo sensor to get accurate temps.
ok im using atitool right now
630/923 and its doing the stress test. its at 77 degrees...is that too hot?

Have you thrown a heatpipe cooler on that 8800 GTS card yet? I didn't OC mine -- haven't got to it so far -- but it would push 70C until I put the ThermalRight HR-03-Plus on it.
They tell you to put a fan on it especially for gaming. I did this in conjunction with mobo ducting, and no matter what I did, the GPU would just stay between 42C and 43C. I finally just decided to dump the fan, and -- again -- no matter what I do to make the 8800 work, it just stays at 51C. I saw it spike up to 55C . . . . . once.

bonzai can you link me to what you mean?
i have the evga version so it has a fan +hs that covers the entire side of the gpu.

so i found that..it looks ultra sexy but where would it go? would it involve me removing the stock one?

hey is a temp of 65 ok?
or is that bad.
im getting in the range of 60-65 with the max cpu stress test.
is my cpu gonna melt down??
If using speedfan then you need to add 15C so 80C in your case.
If using coretemp, then it already shows your real core temps.
What cooling are you using?

If you look at this Zalman cooler you linked, the 8800 graphics cards aren't included in the compatibility list. there are very few coolers out there currently that are made to work with these cards.
ThermalRight HR-03-Plus for 8800-nVidia-series VGA
What I find to be lucky about this, is that, first, ThermalRight is the only manufacturer, or only one of a very few, that has an 8800-compatible cooler. Now you'd think that with a near-monopoly short-run position in this market, they'd really boost the price of the cooler -- but they didn't. Figure the manufacturing cost to make the HR-03 series is about equal to what it costs to make an Ultra-120-Extreme CPU cooler, or an Ultima-90, or whatever models they still make. So the price is in line with those other ThermalRight coolers.
Second, you'd figure that with few competitors on the 8800 VGA card-coolers at the moment -- in the "short-run" -- you wouldn't expect the cooler to perform to stellar limits. All they'd have to do is make a cooler that just improves a little on the stock cooler, or enough to make people decide that $50 is worth 10C or 15C drop in load VGA temperatures.
But I'm rather stunned at the performance on this item. Let me explain.
You can go to Cases & Cooling and find my epic thread on motherboard ducting. You don't have to, since I'll briefly explain here, but I'm telling you where it is if you think you want to look at it.
There are two orientations for this HR-03-Plus cooler -- both equally effective. It's explained in their instructions published on the ThermalRight web-site. You can mate up one side of the heatsink base with the GPU so that the heatpipes go up and over the VGA card with the "cool" ends and fins between the VGA card and the CPU (and its cooler), or you can use the other side of the heatsink base so that the pipes and fins hang over "PCI-slot real-estate" below the component-side of the graphics card. There might be reasons why you would want to use this second orientation: for instance, some motherboards like mine have on-board sound with the "sound-riser" card that fits between the VGA and CPU. It just barely interferes with the HR-03-Plus, so initially, I had the pipes and fins hanging over a PCI-E slot I really wanted to use for a RAID5 controller card.
But if you're going to have two graphics cards in SLI, you'll want the fins and pipes between the VGA and CPU for the primary graphics card, and you'll fit a second graphics card (and supposedly another HR-03-Plus cooler) any way that allows you to use available PCI or PCI-E slots the way you want to. This still means that with the second graphics card, you may lose the use of this PCI slot or that PCI slot -- a good argument for water-cooling the graphics cards.
So I had the fins sitting between the VGA and CPU, as I said. TR says "use a fan with the HR-03-Plus" as a cautionary note. I wanted also to "duct" my motherboard, to drastically cool the chipsets and mosfets with air, and part of the idea was to duct the CPU cooler (Ultra-120-Extreme), even though that part of the equation is marginal because it is a very effective cooler. So how am I going to get a fan between the ducted CPU cooler and the VGA card? Only by flipping the CPU cooler around into a less effective position, but ducting the CPU cooler still gave me fairly good performance, and I had a 92mm fan on the graphics cooler.
That's how I got the VGA to stay at 42C while gaming like crazy. Keep in mind that a small duct-box was built into my ducts to channel air away from the HR-03-Plus and down onto the motherboard, where it was sucked away through the motherboard duct to the exhaust fan. This increased in every way the airflow around the cooler -- beyond what you'd get without any ducting.
Even so, I didn't like the orientation of the Ultra-120-Extreme, and wanted to flip it back around. So I expunged my 92mm fan from the VGA cooler, and built a duct extension that forced air through narrow passages up and over the VGA card and past the HR-03-Plus fins. Here, the idle temperature on the graphics card went back up to around 51C, but gaming and loading up the GPU didn't result in any increase, and I have the log-files for GPU temperatures that show it.
ThermalRight should probably pay me for inadvertently promoting their product. But I'm just reporting objective fact here.
