Yes I've run all those as I mentioned also sfc and chkdsk. Superantispyware had a lot of tracking cookies and a few other things which I cleaned up. Same with adwcleaner so I'm waiting to see if they have an affect but I doubt it.

Tjunction? Do you mean TJmax distance temps?
The cpu is always around 42 idle and with a game it will rise to 60 Prime 95 will push it higher but this is the original I7 920 which runs a bit hotter than the more modern ones and it is overclocked to about 3.6mhz from 2.67

DWM is taking (according to task manager) 22mb private memory. According to process explorer it quotes the working set as well which is about 45mb.

Ok now the Tcjunction or T case is the max operating temp of the CPU see this for yours http://ark.intel.com/products/37147/Intel-Core-i7-920-Processor-8M-Cache-2_66-GHz-4_80-GTs-Intel-QPI as you will see it is quite low as CPU's go most Intel temps are around 90 - 100C which looks as if yours is running at two thirds throttle in idle which means at high use you are very close to the max temp the CPU is happy at and I think you may have to reduce the clocking a bit or replace the processor with one that will take the load.
.
To see just what this means https://en.wikipedia.org/wiki/Junction_temperature
Now most of the modern CPU's have a thermal cut out system in place when the temp reaches un favourable or un workable temps

Now I think now might be a good time to replace the thermal compound and I don't know what you like to use but I always use Artic products in particular the cleaning / preparation kit and the Arctic Silver 5.
Arctic Silver Incorporated - ArctiClean then Arctic Silver Incorporated - Arctic Silver 5
There are a plethora of methods people like to use but I do this.
Remove the cooling plate and clean the cooling system plate / heatsink and the top (heatsink) of the CPU with the Arctic cleaning liquid (some citrus oil based liquids will do the same thing) then after removing all the old compound taking care not to get anything spilling over into the CPU socket I then use the Arctic preparation liquid to make sure both surfaces are in pristine condition to take the thermal compound. I then het a vinyl glove and with my index finger spread the Arctic compound thinly over the entire surface area of the cooler plate and CPU top. I then place a rice grain sized spot of the compound in the centre of the CPU and reattach the cooler plate taking care not to over tighten it.
I find this method ensures the compound completely covers both surfaces and allows for the spot of compound to "bleed" through the thin layer to ensure maximum cooling area coverage. This bleed process does not take long and usually within an hour the compound will have settled to an even thickness. Now I say thickness but it really is only to ensure heat transfer form the CPU and the cooling plate by filling the microscopic imperfections of those surfaces because under a microscope one would see scratches and indentations invisible to the naked eye so in effect the heat is travelling through the compound from surface to surface in this instance.

Ok, I think there's a confusion here. Tcase is different to Tjmax. The Tjmax for the i7-920 is 100 or 105 degrees as I remember. Tcase appears to be the maximum temperature of the metal casing (ie. where you put the thermal paste). The core temperatures which are reported by the sensors and reported by utils such as coretemp are the inner core temperatures and not the casing, for which I don't think any sensors are available.

"Case Temperature is the maximum temperature allowed at the processor Integrated Heat Spreader (IHS)."

Having said that you are right in that I haven't really replaced the thermal compound since I switched to the Corsair HX80 water cooler. This had it's own pre-applied gunk so I should do it. I have a tube of GC Extreme which I believe is better than Arctic 5 so when I've got some down time I'll do it and see.

I do know though even without overclocking the temp of this was never that good - best I remember was idle 38 degrees. It's 45nm so it's not as cool as the more recent offerings.

Edit: I've just looked it up and confirmed that TjMax is indeed 100 degrees for this. Ran Coretemp and that reads TjMax as 100 as I believe that data is held in a register.

Edit2: just to check others - I am pretty much in the ballpark apart from those that have fancy watercooling.
i7 920 owners, what is your average temp? - AnandTech Forums
I would be happy with 32-38 and new paste may get it down a bit but I doubt it will make a massive difference.

Well I cannot find those figures I was only going by the Intel reference - usually there is a Tjunction temp given. Now other forums do say around 50C is quite high for this CPU - one example Core-i7 920 temperatures - Intel i7 - CPUs But if you are happy with that temp then it's your machine and choice.

Personally I don't agree thast there is anything apart from the liquid metal compound (very expensive) than Arctic Silver which contains elemental silver easily the best thermal conductor there is. As you said the gunk that come with coolers is usually not that good with the exception of some of the Noctua compounds but I always discard those any way.

If you are interested if you run HW Info the first screen up will let you know what each core is working at - frequency that is and you may be interested in running this program to see what is happening in the rest of the machine as the reports are quite detailed. See my ditty and pics

Using HW Info

PART A:

You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right handwindow select Sensors and scroll down to the power section where you will seewhat the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT is a dead give awayyou are in the section for the rail voltages. There are other section titlesand one that pops up often is ITE

Now the voltage on the different rails have to be within 5% =+/-of what is required or the machine will not work properly if at all.

See this for the rail voltage info

http://www.tomshardware.com/reviews/power-supply-specifications-atx-reference,3061.html (Section 2.)

The original right hand window shows the machine running and ishandy for that but for looking at the components in some detail close it anduse the main left hand side panel

FOR OTHER COMPONENTS

PART B:

Open each small square with + in it on the section thecomponents are in and then click on the individual component/s (it will highlight in blue) - in the righthand side will appear all sorts of details including brands speeds and otheressential info that particular device. See pic for example.
USE PART B: to check out the CPU for example.

There's a couple of things. The thread you link to, he is 10 degrees hotter and running at 2.66 I believe. I tend to clean out the radiator and dust mask I placed on it if I see anywhere near those temps. Ambient is warm at the moment so 40 doesn't alarm me.

I did this some time ago but you made me think and so a few more checks to avert paranoia and panic on my behalf :

Problem is a lot of these guys are not saying if they are overclocked or not, so when they don't and others chime in about being normal temps, I'll assume they are running stock.

Core i7 920 idle temp high - Power Supplies - Components
https://communities.intel.com/message/84753

So I have to be reasonably happy with my temps as I am overclocking a good 1Ghz above stock.

The thing I noticed when going from stock heat sink to a good heatsink (and then the hx80) was that the idle temp wasn't massively different but when under load it was much much lower by comparison.

This is what I've got on coretemp as I write. Note the Tjmax which is also confirmed by HWinfo which puts it as 'distance to tjmax' ie. it subtracts the current temp from 100

I'll go through the rest of your post and follow your suggestions later as I've got a bunch of things to do.

Oh the paste, forgot. I did a lot of research at the time and it really did come out on top. A quick search finds this but not the one that made me choose it in the first place. It's the second one down. Note what they say about Arctic silver 5

Yes well each to their own I suppose I have never used anything better than the Arctic and I live in an area of Australia where wee regularly get ambient temps in excess of 35-40C. The metal one which I cannot remember the name of now was actually a metal that molded in place when heated up by the CPU but it was a use once only product and very expensive.

Anyway you seem to have things under control now so good luck with whatever you find.

I thought it was arctic 5 I seem to remember it needed a period of time after application where it would perform better after a time. The only thing with the GC stuff is it's very thick so not easy to apply.

Not sure if I have things under control as such, just don't think temperature is a problem.

However, I do want to thank you for your time and helping out.
