True Temp vs Core Temp

[Heligrin]

Just got a new computer that i was working for and i was looking at my temps in two programs that the OC guide recommened: Core temp and Realtemp. Well there is a big disparity between the two.
My system:
E8400 C0 3.0GHz
4gb Gskill 1066
2x Evga 9800GTX
PCPC 750W silencer
Evga 780i

My temps for load in core temp are:
~59C
~58C

My temps for load in Realtemp are:
~50C
~49C

Idle in Coretemp:
~52C
~50C

Idle in Realtemp:
~42C
~40C

Now i have a xigmatek S1283 heatsink with the backplate. I am curious if those temps are a little high no matter what for my processor. Bios reads about 37C idle. Should i re seat my heatsink? I might have put too much AS5 on. My AS5 is also 3-4 years old(does that matter). I put a little extra AS5 on because the retention mechanism doesnt really spread the compound out that well (did a test before i put it in my case).

What should i do?

coretemp reads core

truetemp reads the motherboard sensor like your bios

 

[kpo6969]

RealTemp = TjMax 95c
CoreTemp = TjMax 105c

Considering my temps should i re seat my heatsink?

No. Especially if you have a standard heatsink. Your temps aren't that high.

 

[Team42]

Isn't the Xigmatek S1283 one of those HDT coolers, and supposed to be one of the best coolers available?

If so, the idle temps reported are prob way too high, due to one of three things, if not all:

You've prob used too much AS5
Your AS5 has prob gone off
Neither temp tools are reporting the temps correctly because your CPU is an Intel E8400 which is well known to show strange temps.

Are you using stock vCore? I assume you are, given your CPU is clocked at stock. Are you using CoreTemp v0.96.1? If that's the case, you shouldn't be hitting anywhere near 40C at idle, unless you live in the Sahara, it's a particularly sunny day and your air-conditioning has packed in.

Given the cooler, I'd say you may have a cooler seating problem but, more likely, it's the misreporting of the CPU temp that's the real issue. Get some new TIM and reseat the cooler if you're worried and check temp in BIOS again.

Or better still, I'll swap you my E4300 for your E8400. I'm sitting at 35C idle despite the overclock.

Temps are usually relative and don't mean as much when comparing one system to another. There is a fair amount of error in the sensors typically. I don't think you have any problems.

 

[error8]

Your temperatures are just fine. Don't worry about it.
Like Kpo6969 said, both CoreTemp and RealTemp show exactly the same temperatures, the only difference is that Tjunction for CoreTemp is 10 C higher then RealTemps.

What voltage is the E8400 at? My E7200 @ 1.32v, 3.8GHz idles at 32c, 975RPM, and 100% load at 58c, 1200RPM, according to Real Temp.

Too much thermal paste is probably not the problem. It's probably the push pins not being fully in, or possibly the fan speed is being set too low by the BIOS.

Also, as Team42 said, it could just be misreporting the temps, E8400s have been known to do that with some BIOSes. Those temps aren't anything to worry about though. Try overclocking it higher and see how the temps are then.

assumption retracted
you know what they say when you assume

Great info to live by, and from a 30 sec thought! As every rig setup and environment are different.

dude you guys can NEVER ASSUME since Person X has this temp Person Y will have the same temps.

NEVER.

Reason is there too MANY UNKNOWN varibles at play.

Example, how well is his case management.
How well is his airflow.
How cold is the room.
How cold is the air going into the sink.
How well did he mount,
how many times did he mount.
What tim was used,
HOW much tim was used.

Was the cpu lapped
Was the sink lapped.
Was it pushpin or hard mount or spring mount
Do you have a program running in the background thats taking up cpu cycles.

This is just thinkn for 30sec. Give me 10min, i'll give you a 500 word essay on how many things can change your idle temps.


So please no comparing temps. The only temp you can say its okey or bad is the MAX temp your cpu loads on.

Have you calibrated Realtemp?

 

[Heligrin]

resat my heatsink, dropped my idle temps into 34/36 and loads of 44/46
