Wolfdale E8400 temps - Page 2

post #11 of 28
Of all the thermal sensing utilities, CoreTemp records the highest. It also seems to be the most reliable from what I've experienced. Better to use the highest readings for the yardstick instead of the low ones.
I still have another 10C to go before the 72C max is reached.
I'd be surprised if in the future we all find that CoreTemp was reading too high.

Mine are almost the same

Coretemp reads

idle: Core1: 42c / Core2: 42c
load: Core1: 52c / Core2: 59c
"CPU temp": 47c load, 25c idle

PC Wizard reads

Idle: Core1: 37c / Core2: 37c
Load: core1: 47c/ Core:2 54c

Screenshot (HW reads the same are Coretemp)

Yes, these readings were from coretemp; I confirmed with Speedfan. They both say between 56-58 C now, after a heatsink reseat. Speedfan says "Ambient" is 46 C, and the HDD is 31 C, for whatever sense that makes.

Speedfan Temp1= 40ish, Temp2=30ish Temp3=lower. CPU fan is running at 1400-1600rpm. At least I think it's the CPU fan, it calls it fan1, but that's the only fan I have plugged into a motherboard fan header.

Are these temperatures for real? I don't want to run my CPU at 60 C 24/7...

Vcore2 can be your memory voltage, especially if it hits the 1.8-2.3v range.

We are all still waiting on updates for the various thermal utilities for the Wolfdales.
They should be coming out soon I would think.
Intel seems to have started using sensors that have been recording inaccurately at the lower temp. spectrum.
Kind of like having a car tachometer registering at 4000rpm when its only running at 2000rpm. It only begins recording accurately when it nears the last 25% of its boundary, not totally linear/progressive.

well i just laughed when i put coretemp on mine bios reads about between 29 - 31 idle on my e8200 and coretemp reads 46c what the, ageis panel on the mars reads 29-31 as well i think the coretemp is way out myself.

I found that using a utility like PC wizard or core temp was way high up around the 40s idle... yet my bios/gigabyte utilite reads idle at room temperature or there abouts....

I would think at 40ish C the base part of my 9700 would be warm when its cool... I don't know what to think with such a large discrepancy in the temperatures...

Are these temperatures for real? I don't want to run my CPU at 60 C 24/7...
First, download speedfan 4.34, beta 38, it has the most up to date software for sensor readings.

Then click on configure and you can figure out what temp1, temp2 etc is, and rename appropriately. On mine, temp 1 is my mobo/NB, temp2 is my cpu, yours may be different depending on what mobo you have. just run orthos for 2 seconds and see what temp jumps up of temp1,2,3 and that will be your cpu temp, the other is likely your mobo/NB. You can then go to configure and click/wait a second on name under label, then rename like I have. And uncheck the sensors, that are not on your board. (see pic of mine)

Ambient temp is a temp sensor on your video card, dont ask me why it is called ambient, but has nothing to do with ambient air temps, I just uncheck mine using configure and ignore it.

Regading coretemp sensors, intel engineers have posted more than once to go by the cpu temp (though unfortunately even that is inaccurate on some mobo). Coretemp displays core temperature by using... Tjmax (which has been wildly guessed to be 105C by coretemp author, despite intel saying there is no Tjmax for desktop processors) and subtracting DTS (degrees in C "headway" before hitting the temp at which throttling begins), which coretemp is accurately reading directly off the chip. Intel engineers have repeatedly said DTS is accurate for throttling at high temps, and say nothing about the apparent inaccuracy at low temps. Also others have argued that approximate Tjmax is 100C, like speedfan uses, thus core temps are 5C lower than coretemp reports, others argue it is closer to 95C and thus 10C lower than coretemp reads, and intel engineers say they are all meaningless numbers and just use DTS (degrees celsius from throttling temp). But intel requires a NDA before a full explanation, so who knows. The discussion between the author of coretemp and intel engineer is here, you may have to register to read, but it is free and easy to register. If you cant navigate there from my link, go to softwarecommunity.intel.com, then forums, then watercooling catchall section. There are many temp discussions with intel engineers.
http://softwarecommunity.intel.com/i.../30244450.aspx

Also the rumor mill is that the reason the E8400 chips for sale has dried up, and that retailers are saying they dont expect more in until mid second quarter, is that intel is going to do something with sensors so more accurate, but rumors being rumors, who knows if that is true.

My readings are from coretemp too. My BIOS readings are of 25-30C at idle. I re-seated the heatsink, and this time I took the mobo out to make sure I'd do it well, but I still get the same temps. Hopefully coretemp's readings are too high. I'll try the lastest version of speedfan when I get home.

My E8400 is at 35 in PCProbe2. But Core Temp tells me it's 45.
