My pc has always been under my desk on a small platform I built. The temps were constantly 30c Idle and 48c Load. I put it up top on my desk and my temps dropped to 28c Idle and 47c Load. Nice, it dropped; Nothing to write home about. So, after a week I put my side cover back on which has a 80mm fan attached. My temps is now 21c Idle and 40c Load. 40c Load is the highest temp recorded; the average load temp is about 38c. Average idle temp is actually 21c. So figure a 10c Load drop/9c Idle drop..

Try to move it up top if it isnt!! :)

Whats your ambient temp??

Those low 20's lead to think the sensors are wrong, even though its idle.

I checked it with another sensor and it is indeed correct. Surprisingly, actual temps. Ambient temp was/is 74F, like usual.

u'r CPU can't be below room temp. 74F=23C 20C=68F

did it surprise you that a fan cooled stuff down?? my computer does the same thing when i turn on a case fan(or few). i think you may have discovered something better than toast(inside joke).

toast story.

TOAST. A piece of bread, crisped in a small countertop oven, perhaps topped with a fruit preserve or condiment. So simple.

So perfect.

I strongly believe that Toast is the very thread which holds together the uneasy seams of modern society. Therefore, it seems only appropriate that I pay some sort of homage to this humble Slice of Heaven.


moving air w/ a fan is FAR better than toast now that i think about it.
 
Of course it can be below room temp. And ambient temp was 72-74, like usual. Just thought I would post this for a possible cooling solution.

72 F = 22c, exactly as it was running.. check pics.

Our systems main components are nearly identical including my current O/C. My idle temp is almost always 32-34C year round.
My house is centrally heated and cooled and thermostat set to 72F.
A Zalman 7000cu isn't the most aggressive cooling possible but definitely very effective. What's cooling your CPU? I want to corner the market on that thing. :eek:

its physically impossible for "air" to be below room temp. you are thinking of wind chill. take it from an engineer that has taken heat transfer classes, besides the fact that it is common sence. to put it straight forward, if the air is 33F(0.5C) standard water will not freeze. Put a breeze of even 100MPH on it, the "wind chill" temp will be 6F(14ishC) the water will not freeze because ambient temp is still 33F(0.5C).

also, the core could not be room temp, w/ ALL my fans running at 12V my system will sit 5C above room. which is probably still off b/c those sensors are hardly ever correct. the core is always drawing electricity, which is putting out 60-90watts depending on your CPU, try to cool even a 40 watt light bulb when it is on, same difference.
