The difference good cooling makes...

Well some of you might have seen my posts asking about overclocked Q6600 temps.

So you all know I was running a AC7 Pro in a Lian Li case with 4 80mm fans and I was getting these temps running at 3.45gig

Toasty!

And now running at 3.5gig
This time I'm running a proper cooler (Tuniq Tower 120) running only at 1350rpm so much quieter than the AC7Pro.
I also now have an Antec 900 case with the two optional extra 120mm fans. The case is still amost silent, all fans are at low speed setting.

Thats better!

Not using the same temperature software = fail

lol it makes no difference as they read exactly the same as each other. I don't use coretemp because for some reason it does not run unless I disable driver signing, while CPUID Hardware monitor does!

Edit, to prove the point. I just got CoreTemp again and took a screenshot of them both at the same time

It's the same chip and the same vcore in the bios, it fluctuates in CPU-Z just like all motherboards. The latter pic shows the chip at idle and therefore speedstep has kicked in and reduced the clock speed.

Must be something wrong with your motherboards then because it clearly does on mine... or certainly it jumps from 1.34v to 1.4v under load.

Coretemp is reading the VID wrong anyway. So not only does it need a reboot, it gives inaccurate results. The HWMonitor program is showing the same kind of VID readings CPU-Z does.

If I could record a video of my screen I'd show you

Absolute rubbish!

Calm down chap, anyhow whats with everyone picking holes in my results. I just wanted to show everyone the difference a new cooler and case can make, hardly rocket science.

Was just trying that. I pressed F9 to record a movie and nothing happened. Got to go now but will try again tomorrow night!. It jumps from 1.33v at idle to 1.4v under load in Prime95 torture.

Oh what's the VID then? :confused:

This might explain my confusion, I thought you were referring to the CPU core voltage.

I only ran the chip long enough at 90 degrees to take that screenshot really, it was obvious there was a problem but people kept insisting the AC7 Pro was up to the job despite evidence to the contrary

I took it off, lapped it and got lower temps but they were still much too high so I invested in the Tuniq and the Antec 900 and thats really done the trick

1.2625 > 1.1625 V ?

The VID doesn't change on mine , regardless of idle/load or speedstep .

Ah btw I solved this mystery.

Looking in the BIOS I found the VTT FSB Voltage is set to 'Auto' so it's my board increasing and decreasing the VID voltage depending on the load. I can set it manually if I wish but there wouldn't seem to be a lot of point.
