e4300 temps

[CMC79]

I began overclocking my e4300 and I've got it up to 2700mhz, but I'm concerned my temps are high. I'm idling at 49-50 degrees and going up to 70-71 under load. Is this too high? I've bumped the voltages up slightly because I wasn't stable at stock, and I think I can get more out of it, but I'm just not sure what temperatures to keep it under.

I think you're pushing your luck with that.

I was getting the same temps with the HSF so I got my hands on a Tuniq Tower 120 and that dropped the temperature by 20 degrees.

I just can't get my motherboard to give me a higher fsb than 305mhz :S.

61.4°C is Intel's stated max for that CPU. Above this temp you will accelerate the process of degradation.

You should look into better cooling if you are going to keep that overclock. 😉

Speedfan has me at 34 degrees while idling, while TAT has me at 49-50. That's a pretty major difference. Which is a better measure?

Dropped down to stock speeds and stock voltages--TAT still has me idle at 49-50, but under load goes to 65. Speedfan has me at 31 degrees idle, and goes to 46 under load. One of these can't be right...

I think your issue is TAT. I have not tried it. Asus Probe II, AiSuite, SpeedFan, all report my temps in the low 30's at idle. The new version of SpeedFan which supports the Core 2 Duo with a report on both CPU temps shows them lower still - in the 23 C range. This does not seem correct to me though. Asus Q-Fan runs on quite slow speed at idle, if I use it. Decided not to.

Yeah, I think TAT has to be inaccurate in this regard. Dropping back to stock settings made almost no difference in what TAT read, with top temps still going into the mid 60's and the idle temps at the upper forties/low fifties. PC Health in the BIOS shows temps in the upper 20's while idling. I dropped my overclock down to 2.4ghz but left all voltages at stock--I just upped the bus to 266 like a regular Conroe and left everything else alone. Temps maxed out under Speedfan at 50 degrees while running Orthos, and idle in the low 30's.

Does this make sense?

i've read that tat is off by 15 degrees celsius for E4300 cpus

 

[CMC79]

Fifteen degrees difference definitely makes sense--using Speedfan and CoreTemp I consistently get about 15 degrees difference between those two and TAT, both idling and under load. That makes me feel better--I couldn't imagine that my cpu was overheating while at stock!

This post over at Tom's may help.

tat reads directly from the chip itself if im not mistaken, its the internal temp of the cpu itself...while speedfan uses the board sensor.

Not true on the newest speedfan (4.32).

 

[imported_Truenofan]

didnt know they released a new one. ill try that one but under load i usualy still get a higher temp with TAT

edit: speedfan 4.32 for me still reads 2-3C low at idle, and 1-2C high on load compaired to tat.

edit2: and yes im looking at core0 and core1 on speedfan.

Close enough to be margin of error IMO.

Edit: Especially since my SpeedFan temps fluctuate pretty constantly during load. (2-3C)
