Hey,

Just brought some new hardware:

e2160 c2d
Gigabit ds3r
8800gts
2gig Giel ram

Plugged it all in. Bios reported 23 degrees idle in bios which is comparable to my last temps on a 3500+ which had the ihs removed.

I have a raditor with three 120mm fans and a swiftech storm.

So I get everything installed and TAT reports that the temps are :

Complelty idle.
core 1: 46
Core 2: 43

Load:
core1: 54
core2: 52

It just sucks becuase I installed a 2140 for a friend last week and he had an arctic cooling freezer 7. Idle @ 21 load at 25. (at 1.6 ghz) at 3 gz its like 35 load.

The IHS seems to be fine and I have used the line down the middle method as shown on the arctic cooling website.

:(

Should I ignore tat?

Edit: 27 degrees after going into bios straight after load test. Dubuteeeff?

Edit: Everest is reporting 27 idle, 35 load. Anyone want to bet which temp minitor im going with?

Don't the DS3R's read low anyway. Seen reports of people adding +15ºC to any readings for cores.

I'd believe TAT anyway.
 
The high temps reported by CoreTemp/Everest/TAT with my E2160 are difficult to believe too. One thing I've found with my latest testing is that the CoreTemp 0.95 and Everest reported core temps have a ~1c difference whereas TAT shows a ~5c difference.

What is the Tjunction in CoreTemp 0.95? For mine it's 100c whereas it's 85c with CoreTemp 0.94 and the core temps are reported a lot lower.

Straight after I took this I jumped into the bios and it reported 22 degrees on cpu which matches everest.

I want to beleive that tat is wrong, but I havent seen any cases that are like mine where tat seems to be reporting a higher temps that bios. I realise that windows might be a little more cpu intensive but completly idle it should match the bios.

I dont understand how it can go from 36 idle to 22 in bios straight after.

BTW I havent updated the bios or any motherboard drivers. They were from the disc. You reckon updating the bios will show correct readings on tat?

Thanks for replies guys. :)
 
Everest reads from the Bios, so that's why it's the same.

Core Temp/TAT read from the thermal resistor in the chip itself, independent of the bios, which then calculates the temp using the T-Junction. That's why you get two different temps depending on whether you're using V0.94 or V0.95 as the two versions use two different T-Junction settings.

Bios motherboard/temp sensor readings are not even relatively accurate I'm afraid.

On a related point, the E2140 does seem to be a particularly cool running chip, I have one in my other system which is 27c idle and 40c load, compared to my E4400 which is usually idle at around 37c and loads at 55c. They are just on my systems in the same room though, so only relative to my own situation, and they may be innacurate as well!!
 
Doh.

Well I dont see how It could be running that hot at all unless it has a duff IHS. The side of the waterblock seems cool and the water also. I have repasted the thermal paste too and that made no difference.
 
The load temps are the ones to worry about anyway really, and those of your E2160 look fine to me.

I would be inclined to think that the E2140 temps on your friends pc are a bit optimistic to be honest. How were they measured?
 
They were measured with tat. And they corrosponded with the temps in the bios. Looks like Il have to do some investigating and ask my friend if its allright if I take my pc round and swap cpu's over to see if his runs cool in my setup and mine in his.
 
Now running at 3.2ghz Orthos stable ( Only tested for 10 minutes). Had to take it up to 1.475 volts.

Loading at aboiut 60 degrees which isnt that bad I guess. Not great for water but meh.

Its a cheap chip and if it blows its only 50 quid spent. Il get a e2140 next time :)

Luck of the draw eh? :)

It does 10300 3dmarks 06 which isnt too bad either. 600/900. Reckon I could take that further?

At aforementioned friends house. Stuck the e2160.

So it seems to report the same temp even though his e2140 runs at 36 ish load. Il be posting a pic of his temps when I swap them back over. Looks like il just run it "hot" and duffs up il get a nice cool e2140 like him.

My E2140 runs very hot so don't buy one thinking they are all cool.

I suspect the silicon these chips are made from has a *mutant* defect that makes the chips run hotter than normal, hence why they get binned down to the cheaper product.
 
It's always pot luck with CPU's though isn't it!

My E4400 seems quite 'hot', my E2140 seems to run quite cool, though admittedly it's not clocked all that high.

My E6300 was quite cool, and my E4300 was quite hot!

Those load temps on your E2160 are not bad by any stretch though, not at that clock anyway.
 
Running TAT on my E2140 seems to give similarly good results.

I've just run Coretemp Beta V0.95.4 on both my Core2 machines, and on the E4400 it identifies the processor has having a Tjunction of 100c, and on the E2140 a Tjunction of 85c.

I wonder if Coretemp is identifying the Tjunction correctly on the 2100 series? It might explain the cool temps?

I wonder if TAT assumes all Core2's have a Tjunction of 85c? Does anybody know when TAT was last released, I guess it's quite old now?
