E8400+9700LED temp question.

[CreasianDevaili]

I was running Orthos on a longer run. I stopped it at 17 hours stable. Anyhow, this is from earlier in the run, and I was wondering if my 9700LED is doing it's job. My other processors were amd, so i am unsure of the temp range for c2duo wolfdales, and I know there is some issues with temp readings.

I am just running this out to everyone to ask how they see my temps. I dont want to risk burning up my system, and i dont want to run "along the heat wall" either.

53C is a little bit high, but not really anything to worry about. I aim to keep it under 60C, but I'm happier under 50C.

It's fine. Conroe processors could take up to maybe 70C before most people backed off (upper temperature limit). Not too sure about Wolfdales, but they should be fairly similar.

Well here is my problem. Like many others my temps are alittle strange to me. Since when I go into bios right after that orthos test, which lasted 17 hours, i was much much lower.

I noticed that when i start.. say.. Orthos or OCCT, or even prime, my temps jump way up really fast. Like in seconds. Then they go up or down a degree, but speedfan beta always stays under 50c, and coretemp is about 53-54. I shut down the stress programs and the temps shoot way down too fast for me to think that they are correct.

Unsure if this is coming across correct..

Temps seem to jump 7-8 degrees within seconds of starting a stress test and it takes it an additional 2-3 hours to raise up to 10c above idle, then after 17 hours the temps are pretty much the same as they were at the 2-3 hour mark.

Just feels like I have some kind of free-flowing number gap, like it goes up to a certain degree like a error automatically, then then when i watch after many hours i see the stabalized temps. Then, when i stop stress test, my temps zoom way back down just about the SAME speed they went up.

Goes up and down the same speed, very fast on stress and when stopping it. However after stopping the stress the temps are the same as they would be after acually getting warm after a long stress run.

Gah.. sorry if i am not making sense..

Looks very normal and acceptable. And your description of how temps rise and drop is not unusual either, CPU's heat up and cool down really quickly. You should be good to go up some more if you want

I appreciate the words of wisdom.

It is just i am worried i got the same heat sensor issue being reported elsewhere. I guess i will work on my case airflow, maybe change how fans are, and see. However it just seems strange that the temps only went up 1-2c from the first 2 minutes or orthos to when i checked it at 17hours and 23minutes.

I was expecting a more gradual change. I mean from night to day it grew a few C along with my ambient.

Guess I am used to my old AMD T-bird with vcore 1.7 and slowly going up in temps on the Thermaltake Volcano 5. This just seemed strange to me is all.

Yep, that's normal. The processors heat up VERY quickly, and drop down to idle temperatures almost as quickly (depending on air flow, heat sink, etc.) Eventually, all of that heat will raise the ambient temperature in your case, reducing the ability to remove heat from the processor. That's what gives you the extra 5-10C over an hour or so.

Try running the stress test with the case open, and a large desk or floor fan blowing into it constantly. It should heat up almost as fast as before, but you shoulnd't see the extra 10C over a few hours that you had before. There are, of course, other factors involved with the heatsink, thermal conductivity, etc. but this should prove a quick example.

Well that is something i didnt mention i guess.

After the first minute..well honestly the first 30 seconds, the temps reach roughly the same temps as they do when i am at the 3 hour mark, or the 17 hour mark. Maybe 2c higher.

Let me show you what my temps read, being about the same ambient as last night..

2 minutes into the test.. the temps are pretty much what they are 3 hours in, and then 17 hours in. It is a really fast climb.

Temps 2

They lower within a few seconds to almost normal idle temps, so the air flow seems to be good.

I knew temps rose, but I had figured that temps would rise alittle, and then after so many hours rise some more, and after 17 or so be alittle higher. This isnt the case. Just seems to be a solid jump in the beginning, and then nothing noticable even after 17 hours of both cores 100%.

Perfectly normal. The issues people are having with their E8400s are processor reporting either the same temps no matter the load, or people getting 90C even on water cooling.

Yours is perfectly normal. My Q6600 idles 27C and loads up to about 43C on the hottest core. It takes but a few seconds to get there and come back down. My old Opteron 165 was the same.

If i could make a suggestion... use coretemp 0.06 not 0.95.1. There are apparently some issues with the newer version.

Temps 3


Well.. i think i got something resolved. I took the heatsink out after recalling to great detail what i might have fubared up during the first install.

1. The 9700 is tight, but it can still move if you apply enough pressure turning it. I was putting in the 8 pin cpu plug from my psu to the mobo, and it was a tight tight fit with my hand. I remember when I got it in, i hit the edge of the hsf fins with my right index knuckle, and cleaved off the top layer of skin and started to bleed alittle. However in the process I had tilted the hsf. When I turned it back, i think i hurt the layer of grease i had put on it.

2. I didnt know better. I have the thermal gease that came with the 9700LED. I used the brush and coated a layer on both the hsf and the cpu alittle thicker than i should. This time I went and only put a rather thin layer on the cpu itself, and not the hsf as well

3. When I had put on the HSF, i had never used that type of mounting and bracket. I moved it alittle getting it to seat right to screw in the clamp. This time I took alittle more time and got it almost perfect ground zero on the first drop. I only had to edge it VERY lightly one time this time, when prior I was moving it alot more.



This is the first time the new grease has been used. The temps i put up prior to reseating the HSF were after a Week of burning it in. So I am hoping for some better temps soon.

1. I also put a side intake fan on the back end of the HSF. It seems to work well.
2. I Cut out the grill on the rear fan. Seems to help with getting heat out.
3. I am just experimenting, but i have 2 120mm fans in the space in the 5.25 bays between my DVD/CD burner, and my Sunbeam. One to the front bay doors, and one at the very back of the bracket. It seems to really keep a strong current of air flowing into the case, and the 3 front bays is covered with a filter so it should help with dust.



Overall my cpu temps have dropped. My room ambient is the same, if not a tad warmer, but the interior ambient has gone down 3c. My GPU is 2c cooler than it was at 70% fan, but now is just 55% fan, yet cooler.

About 30 minutes into testing the temps on coretemp and cpuid are both 49c, with some jumps to 50c but staying 49c more than not.

So i am like 5c cpu cooler on load. I am sure soon as the grease gets to burn in I will see some more droppage. Overall I am happy.


EDIT: Bios downclocked me to stock, but kept my voltage. Reclocked it to 3.6, and the temps are around 51c now, but staying stable.

3c lower is still good. I believe. Everything else has remained true however.
