I'm currently running my E4300 at 2.0ghz. It's not much of an overclock, but I'm still getting some temperatures that seem pretty high. I'm using SpeedFan for my temperatures. I tried the TAT utility but it wouldn't run. That may be because I'm running Vista x64. I cannot use CoreTemp because there are problems with my motherboard running that app. I've got an Abit F-I90HD.

Speedfan is reading 41c idle and 53c under load on the CPU. Is this normal? If not does anyone have a suggestion?
 
What cooler are you using? And what voltage is your CPU at? Under Vista 64, SpeedFan reports my E4300 @ 3GHz, 1.35v (in BIOS) at 40C idle and up to 60C under load with OCCT. This is with a Scythe Ninja cooler. However, the individual cores are reading 34 and 32C idle.

I'm using a Zalman CNPS8000. My voltage is 1.3. I've backed down to stock speeds and right this minute my CPU temperature is 42c with cores at 21c and 27c.
 
21 and 27 are pretty good temps, I've overclocked my 4300 to 2.7GHz with the factory intel HSF and my cores idle at 40-41, your stock temps are great. Unsure about your overlocked temps though, I can only suggest checking the voltage

if those temps are being read accurately they are perfectly fine. you even have 10-15c headroom before i would back off on the voltage. you should be able to get around 2.5ghz atleast- depending on how much voltage your chip likes
 
Leave the vcore alone and try going for 3Ghz (333*9) if your mobo and ram can do it. I am running my E4300 at 3Ghz on stock vcore right now on air.
 
I'll try a bit more ambitious overclock tonight after work. I'll post the results here. I want to ease into it a little bit because several people have had these boards fail while trying to overclock. I don't want to push my luck too much. :)

Thanks to everyone for the input so far.
 
Okay. I've got the FSB at 278MHz. That puts my cores at 2504MHz. I'm idling at 44C on the CPU and 29C and 23C on the cores. Under load the CPU is at 63C with the cores both at 44C. Is that hot enough to get worried about? If so, what should I do? If not, should I keep going or am I already at the edge?
 
well before i would say to go higher, i need to know what you think is the cpu and what is the 'core' temps. they should be the same thing, both cores are on CPU chip, so the CPU should be a collective reading (average) of both cores, which should be the same temp (or within a few degrees of each other) both cores at 44c is good, but where are you getting the "cpu at 63c" part? that is a large difference between 44 and 63. are you looking at coretemps tjunction part? what monitoring program are you using?
 
I'm using SpeedFan for temperatures. That's how the readings are labeled. They might be labeled inaccurately. I don't know for sure.

I'm using Orthos to load the CPU. I had it set at priority 10 and ran the load CPU test.

Thanks everyone for all the information thus far. I'm learning a lot from you guys.:)
 
orthos is good, run the blend test it will make sure your system is stable in both ram and cpu, download either coretemp or intels thermal analysis tool those will tell you what they realy are. i dunno what speedfan is calling CPU but its probably not the CPU. if either of the two programs i mentioned say mid 40's C you are fine, push it to 3ghz :p

I can't get either of those to run. SpeedFan is the only temperature monitor I have been able to run. There is some sort of problem running CoreTemp on my motherboard. The Intel tool will only flash on the screen for a fraction of a second when I try to run it.
 
The "CPU" temp come from the motherboard sensor while the "CORE" temperatures come directly from the CPU via a digital signal that is encoded. The "CORE" temps will always be lower and more accurate than the "CPU" temp. Don't feel bad about Intels tool, it don't run on my ABIT either. That tool isn't even really designed to be run on desktops, it was meant for laptops.
 
Okay. I've got the cores just over 3GHz. The core temperatures under load are in the mid 50s. Should that be okay, or do I need to be worried?

On a related note, I swapped my standard IDE cables for round ones. The readings coming from the motherboard temperature probes dropped 3-4 degrees each! I'm very impressed that the difference is so pronounced.
 
mid 50s is fine, i would keep going until your getting load temps in the high 60s, mid 70s is even ok for othos load because under normal use you will never see the kind of stress orthos puts out.
 
I'm getting an error in Orthos after about 15 minutes. Would it help any to up the voltage a little? I'm not sure how to proceed in resolving that issue.
 
RADDEVON...read this thread for info on what temp programs to use for monitoring, there is a discrepancy depending on the cpu model. Page 2 and 3 have the latest (and correct info) as a couple of us did some underclocking and undervolting to determine exactly why different programs were reporting different temps. From a post you made I saw something about your cpu idling at 23c, not possible with air cooling if your ambient is higher than that, and most are. Most C2D's run about 3c higher than ambient idle temps.

Thanks so much for the info. I will definitely take a look at that thread.
