Why are my temps so high? (E4300)

Never done any overclocking, but thought i'd give it a try as the E4300 was supposedly so easy to overclock.

Managed to get to 3ghz at 1.45v but my temps are very high 37-39 idle or 67-70 at full load in TAT or orthos. Seems a little on the high side to me? I'm using an Artic Cooler Pro, not really interested in changing it to be honest. Would it be worth knocking the speed down to 2.8ghz to loose some heat?
 
Assuming that you are otherwise happy with air flow in the case you might want to just try reseating that Heatsink. I did both things when my opteron was on the warm side and I reduced idle and load temps by nearly 10 degrees. The extra 2x80mm fans helped I am sure, but it turned out the heatsink was only 3/4 covered with thermal paste.

As for your problem, those temps are a bit on the high side especially in winter and if you can't get them down a bit i'd look to reduce either the overclock or the volts.
 
as said above try reseating the heatsink with a nice layer of AC5 or similar.. also - does that overclock really need all those volts? try knocking it down a tad


good luck matey

Core Duo is rated at 1.35V max, and many of them are actually considerably lower, the VID on my E6700 is 1.2V. More volts is more heat, so definalty worth gradually reducing your voltage to see if it will run lower, while retaining stability.

To be honest, your temps arnt so bad. TAT is the best way to measure a Core 2 processor, but some people still think that their 20degree reading from Speedfan is accurate.

My own Core2 idles at 37 degrees (TAT) both cores, clocked at 3Ghz on 1.2V however my load temps are 60-63 both cores fully loaded.

Of course, dont forget that while the processor is rated with a maximum temperature of 65 degrees, that actually refers to the temperature on the top centre of the heat spreader, as measured by a thermal diode embedded into a heatsink. A rather meaningless figure.

The maximum junction temperature of a Core2 is (I believe) 85 degrees C. If you assume the sensors embedded in the core are reasonably accurate, then it's likely safe to see TAT temperatures as high as 80 degrees.

For personal preference, and the enjoyment of 'silent' PCs without hugh whirring fans, I prefer TAT temps of <70 degrees.
 
Yep, reseated the CPU and HSF last night and applied some original artic silver (from about 7 years back ;)) to the CPU. Just a very very thin layer.

I have dropped my volts down to 1.35v but still at 3ghz and it booted (although it didn't yesterday at 1.4v) which has dropped my temps to 34c idle and 57-60c at full load. Can't understand how dropping the voltage by 0.1v has resulted in a drop of ~13c.

Just hope it boots from cold :)
