damn!

Toooooooo Hot!

didn't know the stock sucked that much, how much voltages was it at when it went to 90's area?

I used the stock intel HSF on my first E6400 Build, replaced shortly afterwards and sinse then have left the stock HSF in the box, ordered my 3rd party HSF at the same time as ordering new CPU.

An old poster here - SupremeLaw (Have not seen in a while" use to say "Intel should be sued over this".

While it is at the Bottom of the heap interms of perfomance, may have had trouble getting the 4 pushpins locked properly.

The vcore is only on 1.2. The cooler is mounted perfectly all pins are properly pushed in the cpu idle's in the low 20's on startup the stock cooler is only good for non overclocking as soon as its put under load its skyrockets in temperature.

A couple charts have the stock cooler as much as 20c more under load then any aftermarket cooler. So this just gos to show dont beleive what people think about the stock cooler yeah it can survive a stock 3.3ghz test on prime 95 ive tested it it hits 70c and stabilises.

But if your going up around the 3.8ghz+ mark you need a after market cooler to run stability tests. Im waiting on my hyper 212+ should drop the temp under full load on 4.4ghz to the high 70c id say.

I must admit the ambient temperature was 25c and my case fans were set to low at the time that in mind i should get a couple degree drops now that ive uped the speeds.

that's good to hear, the hyper 212+ is cheap and should do a good job for you overclocking it that high.

90C+ kind of surprised me, didn't think the stock would go that high especially with only 1.2v core. what thermal grease are you using atm?

Something is wrong, I'm overclock to with a higher voltage and don't go much past 50C when running prime 95 for several hours.

I am using the Corsair H70 which performs better than the Hyper 212 but not 40C better. I would take the heatsink off, clean it and the CPU and reapply paste and try again.

He's actually using the stock cooler in that pic. He hasn't gotten the 212+ cooler yet.

joost:
The 212+ should give you temps in the high 60sºC or lower if you have good case cooling, especially if you install a second fan for push-pull mode on the heatsink.

Sorry I missed that, back to the TC i wouldn't recommend OC'n the processor with the stock cooler.

Ill post new results once i get the hyper 212+ in a couple days. As for now with stock cooler on default 3.3ghz the cpu temp idle is low 20c so i know its installed correctly. Stock cooler cannot handle overclocking load at all.

The 3.4 Ghz 2600 runs at 3.80 w/ Turbo at stock settings so if ya needed an aftermarket cooler to run at 3.8, then every unit sold would fail. You can easily c;ock any SB processor to 4.5-ish w/ the stock cooler. As you can see, you can hit 4.6 Ghz w/ the stock cooler.

http://www.guru3d.com/article/asus-sabertooth-p67-tuf-r...

So these settings allow us to work at a baseline clock of roughly 3400 MHZ, which helps us in IDLE power consumption. However, once the processor gets a kick in the proverbial nuts, it can turbo any or all cores towards that multiplier of 46 times that 100 MHz baseclock frequency, that's a 4600 MHz configuration setup in less than a minute...... Let's have a look at a Prime95 stress test with all four cores active and stressed at 4600 MHz (64 - 69C) ...We guarantee you, you can take it further as well, as we used stock Intel cooling here ...

The 2500 isn't all that different.

Here's my temps at 4.2 - 4.8 Ghz w/ Thermalright Silver Arrow on 2600k

Max Core Temps under P95 (idle - load) 4.2001 Ghz
Core 1 29 - 54
Core 2 30 - 56
Core 3 22 - 57
Core 4 28 - 55
Core Voltage (Idle) 1.016-1.024
Core Voltage (Under Load) 1.256 - 1.264

Max Core Temps under P95 (idle - load) 4.4001 GHz
Core 1 29 - 56
Core 2 30 - 60
Core 3 22 - 60
Core 4 29 - 57
Core Voltage (Idle) 1.040-1.048
Core Voltage (Under Load) 1.280 - 1.288

Max Core Temps under P95 (idle - load) 4.6004 Ghz
Core 1 31 - 62
Core 2 31 - 66
Core 3 31 - 68
Core 4 31 - 65
Core Volatge (Idle) 1.040-1.048
Core Voltage (Under Load) 1.360 - 1.368

Max Core Temps under P95 (idle - load) 4.8004
Core 1 29 - 69
Core 2 28 - 75
Core 3 28 - 79
Core 4 28 - 72
Core Voltage (Idle) 1.032-1.064
Core Voltage (Under Load) 1.408 - 1.416

The Silver Arrow is way way more cooler than ya need for Sandy Bridge.....I just used it because it was the biggest damn ting I ever saw (7" cube installed w/ fans) and it looked like fun to play with .... well the fact that it beat the pants off the competition helped :) . Even the reviewer writes:

Quote:
I think the Silver Arrow represents the ultimate air cooler than can be built and still fit within the constraints of an ATX motherboard and a standard computer case...... It's almost ironic that coolers like this are becoming available just as processors transition to designs that may ultimately render them unnecessary; even overclocked to 5GHz, an Intel Sandy Bridge 2600K doesn't need anywhere near this level of cooling. Still, it wouldn't hurt, and as I noted earlier, there are still CPUs out there that can benefit from it.


I'd get a Scythe Mugen 2 .... It beats the Hyper 212 by 7C and costs only $10 more.

Jack...

They don't show which "stock" cooler they are using -- the ones Intel shipped to reviewers (the "not-really-stock-$55-Intel-aftermarket-tower-cooler" found here) or the real deal (the "really-effing-crappy-hunk-of-metal-Intel-calls-a-retail-heatsink"). Because they said they could overclock with it, they are probably using the not-stock review cooler.
