E4300 Temp Readings.

[joshd]

I am very confused with all this.

CoreTemp 0.95:
-reads Tjunc as 100*C.
-reports 58*C load

TAT
-reports 60*C load

Speedfan 4.32 (latest)
-now gives separate temps for each CPU core like CT and TAT
-42*C load


I have read on these forums that with CoreTemp, I should take 15*C from whatever it tells me, due to it reading 100*C and not 85*C for the TJunction. Doing this gives the exact same temps as what the new speedfan reads. Should I belive CT or speedfan?

I think 43*C load seems more "realistic" for an E43 at 3.2GHz, 1.425vcore, with a tuniq tower 120 than 58*C does. I have remounted the TT120, but that only dropped temps by around 2*C.

whats your temps at stock clock at idle? whats your ambient temp?

[joshd]

stock clocks/volts, it idles/loads at 24/33 speedfan, 38/47 coretemp.

EDIT: ambient I am not sure, I'd guess it is no higher than 20*C. our heating is off, and british summer isnt that hot :P

CT seems to be correct, it recently updated the program with the +15C offset for the C2D core temps.

24C idle would mean it's running very close or at average room ambient temps which ain't right for air cooling.

Go to Advanced tab in Speedfan and select INTEL CORE, set offset to +15 for both cores, check "remember it".

its only the E4300s that is shows as having a 100*C tjunc though? is that correct? I would have thought they would be the same as the E6xx

[stealthbomber]

I'm not sure about the 100C tjunc, I've set my Speedfan events tab to execute a force shutdown program if either core reach 80C

[mascaras]

With me speedFan and Coretemp reads exact same temps

Try v0.95

[mezcal]

TAT and coretemp 0.95 are correct (or closest to correct.)
There's an informative thread on this issue in the help and suport section.

Sorry, I feel you're pain. I wanted to believe those lower numbers too but it just ain't so.

[mascaras]

Try v0.95

same thing , the sensors are the same

[kniwor]

speedfan seems right

[joshd]

its because of the 85*C tjunc.

its only with the E43s that for some reason CT uses a 100*C tjunc, hence my confusion.

It's impossible for the idle temps to be that close to ambient running on either air or water cooling.

Correct. I was referring to the e43 in my previous post. afaik, speedfan 0.94 works fine for e6X chips.
Don't know about speedfan.

[joshd]

It after some googling, there seems to be lots of discussion on this matter. It seems that all C2Ds with L2 revision gets assigned a 100*C TJunction. I doubt this to be the case, that seems very hot for a throttle temp to me.

CoreTemp 0.94BETA reads the same as Speedfan, as it assigns a TJunc of only 85*C.

I suppose the only thing to do is wait until Intel make it plain what the TJunc of the L2 chips actually is?

I get results in line with that. Though i just applied OCZ Ultra 5+ so it hasn't been 1 week yet, so temperatures are still quite high.

same issue for you then, I suppose? do you belive speedfan or coretemp....

i'm sure this whole problem is because TAT thinks it is a Pentium-M... and then coretemp upped the tjunc to be more inline with TAT... ?

[Fr3ak]

CoreTemp is about 15C off. It reads the Tjunction and the temp value saved ina register, subbsract and displays the temp. Now with the Tjunction of the E4300 being 100C, instead of 85C, the value is about 15C off.

I just built 2 E4300 rigs and I would say I know how to mount a HSF. With the Infinity and a roomtemp of 20C, Coretemp showed 43-46C on idle with stock volts and clocks, so I pretty much doubt that is anywhere close to the real temp. 28-31C seems to be more like it.

Here is what TheCoolest (autor of CoreTemp) says:

Coretemp 0.94 reads idle temps of my 4300 to right at or slightly below ambient when idling. Speedfan, when I had it installed briefly, was very similar.
TAT & Coretemp 0.95 agree (very close anyway) on a 15 degree higher temp.
Now I'd much prefer to believe the former but there is zero chance that this chip is idling below ambient air temp.
I'm using the stock HSF.

[Fr3ak]

I am having the impression, that there are different batches of E4300 out.
So for some CPUs the added 15C to 0.95 might be more like the real temp, but for some the 0.94 value was the correct one.

I cant count how many HSHs I mounted, so I am pretty sure I didnt do anything wrong. I used Arctic Silver 5 and one of the best air coolers, the Infinity. I have my doubts that a stock E4300 would idle at 42C. Maybe the chipset has something to do with it? I have no idea, but its strange. With 1.375V set in bios, which is 1.34V idle and 1.33V load, running orthos hits 80C some time between 15 and 19hours. If that temp is for real, aircooling sucks big time to cool overclocked CPUs.

Yeah, I wonder also. Seems like I read somewhere that some 4300's report as conroe and others allendale but I can't recall at the moment where I read it. I was looking into this temp issue prior to the coolest even releasing coretemp 0.95 precisely because I didn't believe the below ambient reading from 0.94 beta.
btw, I had to rma my bx2 and in the process of reassembling everything I managed to lose (well, actually gain) 5-7 degrees. Not pleased with this but haven't taken it back apart to reseat yet. Mine doesn't scale temps well with voltage either-didn't hit 80 but mid-70s with orthos small ffts. I'm thinking about dropping it back down to stock vcore where it seems to be able to run at 2.7 or 2.8 with somewhat better temps. Seems solid where it's at (sig) but with oem cooler I dunno.

Coldpower27 those temps are insane! What cooling are you using? Even with stock cooling at that frequency and voltage those temps are very high, I would really check your contact.
I run my E4300 at 2.9-3.0GHz 24/7 @ stock volts using the stock HSF (for now) under F@H load, coretemp 0.95 and TAT give me temps from 56C to 61C depending on ambient, speedfan 4.32 gives me temps 15C lower so I have set an offset of +15C for speedfan.

I really think it is wise for everyone running an E4300 to stick to the highest reported temp, personally I dont have the cash to replace my E4300 if it goes up in smoke, if I did I probably would have bought an E6600 in the first place lol!

edit: here is a quick screeny

For comparison purposes could you post temps using the Thermal Analysis Tool instead, since then I can see how much more I have in term of C then you. Typically I don't reach the levels generated by TXT as those seem to be worse case.

As well I only just applied the OCZ Ultra 5+ thermal compound it needs a few days to bond, from what OCZ says if I don't see an improvement in a week, i will check it out again.

I am using the Sunbeam Silent Whisper as my cooling device.

Your using the SMP client of Folding @ Home I assume, I can't really duplicate this workload as I don't want Microsoft.NET on my computer.

[hstuehmeyer2000]

core temp .95 reports the cpu temp wrong for e4300's you have to use .94

[coldpower27]

Alright, but what do you get during TAT load for CoreTemp 0.94?
