some E8400 and GTS 512 G92 temp question

[Lazark]

I know there is a lot of topics regarding the e8400 and the difference between the temps on some programs, but thats not my question.Yesterday I armed a new rig, and I wanted to know the "normally" temps that I would expect from it.

please, can you guys tell me what are the normals temp for the E8400 at idle and full load (also, which program did you use to see that)

and also, I have a MIS GTS 512 G92 OC... the same question here, what are the normal temps on idle and full load, and in which program.


thank you.

I use Real Temp. A monitoring program written by an e8400 owner who wanted to more accurately reflect the true TjMAx of the CPU's measured and to allow user adjustments to offset the sticky sensors so common with the e8400. Mine is about 39/30 idle and 65/55 (for both cores) at 3.6ghz, 1.21v.

The gts is around 55 idle, 79 load, this with its stock fan settings which vary from around 37 to 42% fan speeds, measured with Riva Tuner 2.07. Fan speeds now adjusted to more aggressively deal with higher temps (50-65-80% speeds).

I use real temp as well. I keep my E8400 at 3.6ghz at 1.23v and idle temps today are core#1 27c and core#2 26C are. Under Prime95 load my temps are core#1 42c and core#2 40c.

My 8800gts 512mb idles at 43c with fan at 60%, and after running 3dmark06 my temp went to 52c, with fan at 85%. This is stock speeds though.

Here's a pic to show temps at 4ghz under full load. Voltage on vcore is 1.37v 4ghz temps

Temps will vary depending on airflow.

My temps are similar to amenx, but is it just me or do a lot of E8400 owners see such a large disparity in temps. Can this be attributed to airflow in the case or can different heatsinks create such a dramatic difference in observed temps for this chip?

 

[Xpoc]

With amenx's core 1 and 2 temps having a difference of 9-10 celcius, it makes me wonder if there is too much thermal grease applied or whether or not the heatsink needs to be reseated.

My e8400 with a thermalright ultra 120 extreme idles at 22-23°c and runs 33-34°c with both cores under 100% load. Room temp about 20°. gotta luv winter. that is the temps I get with asus probe and speedfan. I'll try this real temp sometime and see what I get

 

[surfsatwerk]

Ok I misread what he was trying to write.

Using Real Temp my cores idle around 38C with max load at 55C at 3.6ghz 1.92vcore.

I've reseted my heatsink 3 times now using AC MX-2 tim trying to get better temps.

 

[Margalus]

Ok, tried with real temp on vista 64 ultimate. It doesn't seem to work. It say's my sensors must be stuck. both cores stay at 34 in it no matter what I do, while speedfan and asus probe are both going up and down with the varying usage.

 

[amenx]

Actually the wide variances between cores of the same chip is pretty common with the Wolfdales and due to buggy or sticky DTS sensors. Many reporting it in other forums as well. I think it will be corrected in future steppings, some are even speculating that the scarce availability of the chips is due to Intel trying to fix it.

 

[Xpoc]

That's true, amenx.
I wonder if the new quads will have the same issues with temps.

I've read that the C1 stepping used in the new quads "doesn?t have any changes to its thermal, electrical or mechanical specifications compared with the previous C0 processor stepping that is used widely in dual-core Wolfdale processors these days."

thanks to everyone...using real temp: 35-39 idle and 52-55 full load..its seems that I attached good the hsf
anyone with gts 512?

Out of curiosity what heatsink are you using on your E8400?

Well, after 7 hours of Orthos 100% both cores, my e8400 @ 3.6ghz on real temp shows 44c on both cores leaving 52c to TJ max. When I run coretemp and have it show the C TILL TJmax it is the same 52c. I will report Idle when I turn this off this time. Worked on my cm690 fans alittle. This is usually 2-3c cooler but its winter and i got a very old space heater in my room that just shoots out extremly HOT air. When its off i get better results. Also the lack of freash air in the room dosent help <sighs>

I only have a 8800GT 512 BFG OC, so it has the first stock cooling revision. I oc'ed the core to 700 and ram to 1950. Idles 29% fan <i hate that> around 51c. I hit it up to 60%fan and i am around 44c. I run 3dmark06 and I am around 55c 100% fance. Crysis and CoD4 for hours of playing only take it to 66c with 100% fan so far. With the oc and the crappy cooling fan/reference on it I am UTTERLY happy with those temps.

I have to agree however. The airflow in your case matters a ton.


Also, my sensors arent stuck on my e8400. They rise and lower together if the load is even, and if it isnt, they are a degree or 2 off like normal. The time to cool down from a long stress test is almost instant.

Using a Zalman 9700LED with AS5 with a drop in the center.

the stock hfs... are you thinking that my temps are a little higher?

No I'm thinking mine are.

http://www.anandtech.com/casec...howdoc.aspx?i=3068&p=4

Judging from this AT review of my HSF I keep thinking my temps should be way lower than they are. I'm going to drop my system back to stock and double check it against what you're getting from the retail HSF.

Edit: At stock speeds I'm showing 47C at full load. I'm going to remove my mobo and double check to see if I didn't install the base plate properly.

It seems there is a difference between the programs that people use. If you are using something different than anandtech used in the review, that may make up for the difference.

 

[surfsatwerk]

I can't get TAT to work with this processor, but the nvidia temp monitoring software reports temps 10C higher than Real Temp. Basically everything tool I have on my system shows 10C higher than Real Temp.

My current ambient temp is 20C so I can't blame the weather for my high temps, I'm fairly certain I'm suffering from a case of PEBKAC.

 

[Lazark]

Now Im begining to worry...35 at idle and 56 full load its ok having the processor at stock speed (3ghz) using the intel hsf?? (readings from real temp)

IMO yes those are the temps you should expect to see with the stock hsf.

But I'm not running the stock hsf, I'm using Thermalright's Ultima 90, which should produce much different results.

 

[Xpoc]

what is your vcore, surfsatwerk?
Mine is orthos stable at 3.6ghz with vcore at 1.23v. I have mch, fsb, and pci-e voltages all bumbed up 1 time.

 

[surfsatwerk]

I can get away with with 1.19 for my vcore and run a stable 3.6ghz. At stock I'm running 1.08 vcore and still get 38C for my idle temps at 20C ambient temp.

I'm taking everything apart right now. Maybe I have an o-ring on the backplate that's out of position or something.

My E8400 running stock speed with stock cooler is sitting at 50C idle, according to CoreTemp v.97. This is with vcore set to auto in bios and reading 1.168v with CPU-Z. Under full load, running Small FFT, it's sitting at 70C with a vcore of 1.2v. RealTemp reads 10C lower in both cases.

After reading this thread, it appears my temps are quite high. I initially setup this machine using a custom WC setup, but after seeing higher temps than expected I decided to try it with stock cooling to get a baseline. The case is currently sitting with both sides off and only 2 120mm fans, one in front and one in the rear. The 120mm in front is mounted to the front of my HD cage that is full with 4 drives, so I have basically no airflow in the case right now.

I'll try remounting the HSF tomorrow and see if my temps improve, but does anyone have any other ideas? I have experience with OCing and mounting HSFs, and I've been mounting this the same as usual so I'm pretty confident I didn't mount it badly, but I'll find out tomorrow.

I can add to the G92 temperature. I have 2 factory OC 8800GT and just recently paid attention to the temps after gaming for a while. They were in the 90's. Not good.

At first I thought I could just reapply some AS5 and everything would be okay. Nope, still got temps close to 80 when gaming. So I bought a couple of Thermaltake DuOrb and put them on and now temps don't get high as 60 when gaming for long periods time. Usually idle in the high 30s.

So its turns out the stock coolers for mine were just junk and needed replaced. I originally wanted the Zalman VF-1000 but my local store didn't have any and I was too impatient to wait for online order.

Here are my temperatures at STOCK speed and HSF using RealTemp:

IDLE (core0/core1): 34C/35C
LOAD (core0/core1): 56C/56C

My system is pretty stable so I am assuming that even though other programs such as CPUID Hard ware Monitor and CoreTemp read about 10C higher (due to a Tjmax of 105C vs. RealTemp's 95C), my temperatures are okay. It seems that without Intel's official Tjmax value, these programs' results cannot be taken as 100% accurate.
