Safe to assume bad application of tim from the factory/dried out?

post #1 of 8
Thread Starter 
3570k, one core around 14c with the other three around 30 at 99% idle.
post #2 of 8

The 1 core at 14°C is showing an extremely inaccurate reading. The other 3 are very likely much more accurate. However, idle temps are usually a LOT less accurate than full-load temps because the higher the temps, the more accurate the readings become.

 

For reference, 14°C is 57.2°F while 30°C is 86°F.

I wish my idle temperatures were that good. How on earth 16°C on one of the cores. I have that 10°C near moderate and idle load. So I'd say it's completely normal. Even changed from heatsink cooler to watercooling. Temperatures match up together on high temperatures. C-States is enabled for me.

10°C is 50°F, so unless you're using some exotic cooling, 10°C is physically impossible. The temperature of a physical object cannot be colder than the air temperature unless you are using something colder than the air to cool it, such as an ice cube (just as an exaggerated example). Or, an air conditioner.

 

I know that some objects feel cold, like metal, but that's only because they are conducting the heat away from your skin significantly faster than something like say your clothing. The temperature of any object that is being cooled by the air can only be as low as the air temperature. So, if you have a metal object that's been sitting around doing nothing for a while, then it is exactly the same temperature as the air.

 

So again, 10°C is impossible without exotic cooling. Water cooling isn't going to do it unless you are cooling the water with a ton of "plastic ice cubes" or something (so as to avoid getting water in the cooling liquid). Small bodies of water are the same: take a bucket of water: if a bucket of water is just sitting out, then it will eventually match the air temperature all the way through to the center and bottom of the bucket.

 

As I said before, 14°C is 57.2°F which is impossible with air cooling unless the air temperature going through the heatsink is a little colder than that. The same is true though with water cooling: if you're using fans to dissipate the heat off of the water as it goes through the radiator, then you're essentially using air cooling and therefore, the temperature of the water cannot be any lower than the air temperature unless the air going through those fans is a lot colder than the air.

here are my i7 970 6 core idle temps. my home office is 70F, so your temps are normal.
I run the Noctua cooler in my sig.
my cpu cooler fan is always at max speed as are my exhaust fans, my 2 intake fans run at half speed except when gaming then they are at full speed.

Heres the idle temps of my over clocked quad core Phenom X4 shown in the notification area (temporarily for this scrshot) by CoreTemp.



Spring cleaning of my fans is in order soon. Will drop my temps around ~4 degrees afterwards. So the slighly high idle temps are normal for me atm.

But as you can see, my cores are equal across the board.

every intel cpu system I have owned or built always has one core that is very cool at idle.
