New HTPC Build, CPU temp reads 40 degrees. Stuck?

Post by Spike_8585 » Fri Oct 09, 2009 9:13 pm

I just built a HTPC with a zotac GF9300-D-E, C2D E7500, cooling with a scythe Ninja2 in a Silverstone SG05. I am running 2 scythe 800rpm fans.

Basically, when trying to monitor my CPU temps, I get 40 degrees on both cores, as a current, high, and low temp.

Anyone have any ideas why that would be?

Take RealTemp, close all all unnecessary background programs and do a CPU Cool Down Test. Post a screenshot at the end of test.

Are you using CPU temps to control the fans?

Unplug the fans and see if the temps go up. Also, I have more than one board where the temps are constant below a certain level.

Ok, so I ran the test...and the temp went up. I am pleased.

Basically it never goes below 40 degrees, for some reason, but at 100% load it says that i am running at 48 degrees. That is pretty cool, no?

I did a print screen, but I am not sure how to upload it. Do I have to host it somewhere, then link it?

My fan is 800rpm, so I just plugged it into the PSU directly, as I figured it might as well always be on.

Maybe I'll try this test again, with only one fan, no fans...

Thanks!

Yep, tinypic, photobucket for example.
From your explanations I understand that your cores are stuck at 40°C. Nothing to worry if they move up in load. :)

Ok, so I think the image should work now. Let me know if I am breaking any rules by posting it this way.

So, I guess my processor will not read below 40 degrees?
I guess that isn't a big deal as it reads higher temps.
So I shouldn't have to return the CPU, right? Because I don't want to have to deal with mount that Ninja2 again.

So, not that I see any reason to do so, but I could overclock my CPU if I am only running 48 degrees at 100% load, without running into temp issues?

Also, why is my proc reporting running at 1.6 Ghz and not full speed? Or is that just running lower because it doesn't need it at that moment?

Yep, your CPU is stuck at 40°C. It's common for 45nm CPU, don't worry. Anyway idle temps are meaningless so if it works in load is perfect, no need to return. :)

OC as high as you can but try to keep distance to TJMax>20 (or core temperatures below 80°C).

Your frequency is 1.6GHz in idle because you have EIST/C1E enabled in BIOS. Again don't worry is a feature no a bug. :)

Great. Thank you!
I was worried.

So, should I disable the underclocking at idle? Or is there not much of a benefit from changing that?

Nope. You should disable EIST/C1E only if your overclocking is not stable. Otherwise you should leave them enabled because you can reduce heat/power consumption when your CPU is in idle.
