How are Load Temps Measured?

The most frequent temps were around the low to mid-60's so I could report my load temp as 64C and that would also be about half way between the low and high.

Run Prime95 using small FFTs. It will stress the CPU more than the other options. In my case it made temps almost 5c higher.

I think that your temps are too high...either sensor measuring wrong, or poor contact between cooler and CPU heat spreader. That is unless you are running the cooler sans fan. That also might explain the jump from 50C to 70C...you may have a bubble or void in your thermal compound.

I could not make my version of Prime 95 (24.4) launch but one application. In the past you had to launch one instance of the program for each core. Need to get the latest, I guess.

Actually, last night I wrote a blog telling about this, but haven't decided whether or not to submit it. Guess not since I'm spoiling it, but I ended up running Prime95, Folding@home, Everest Stability Test, and Super Pi (32M) to finally get my Q6600 at 100% load. Occasionally it would get to 45C, but mostly stayed at 39C-42C. It was oc'd to 2.8xx gigs(I think, maybe only 2.6), 1.5v. At stock clock, it never busted 35C.

Looking at temps that the Geminii gets in reviews, it cools pretty much like my Freezer 7 Pro.

I am using 2 1500RPM fans on the GeminII. My temps range from 59C (rarely) to 70 (only for a second or 2 did I see it hit 70 and this was in a 24 hour period) but mostly were in the low to mid 60's. My temps are high because my overclock was 3.33 but I have since dropped it down a little to bring down the temps a little.

You said you were running at 2.6 or 2.8. Do you really need 1.5v for those speeds? I am at 3.3GHz and 1.3625v.

Nah, I set it there trying to bust 3.0, and to see how hot it gets. I got to 2.8 at stock voltage.

Awesome that you are getting well over 3.0. I haven't had much luck getting much past 2.8 totally stable. First Intel I have tried to overclock, and not really familiar with the BIOS (American Megatrends on Asus P5K Deluxe Wifi). Kind of sux....both the CPU and board are supposed to be good overclockers. I think that the 800mHz memory is holding me back too.

Will have some solitude tomorrow morning. Maybe I'll do better then.

Finally figured out how to max the processor without getting multiple instances of Prime95...Sandra's Burn-in, uncheck everything but the CPU Arithmetic. Seriously kicks the CPUs ass.

The Core 2 Quad has four times the cores, four times the power, and bogs four times as bad when totally maxed out.
