why is my CPU so hot?!?

[Amplicom]

Alright i have my system set up like this:
Antec SX1030B
Thermalright sk6 with the delta fan
arctiv silver 2 paste
ECS K7s5a
AMD 1.4
2x 256 mb crucial ddr

When i set the fan to blow on the heatsink, it idles at around 46-7 degrees celcius and 55 on load. when i set it to suck air the temps read 49 on idle and 59 on load. Whats wrong with my setup? shouldn't i be idleing at 39?
the case 2 exhaust fans, 1 intake fan, 1 powersupply fan.
The temps are taken with motherboard moniter 5 with the patch for my motherboard. the ambient temp is really cold too, dont know numbers but i think its likt 63 farenheit.

my guess is that your intake fan on your chassis isnt doing its job correctly, also, if you dont have a rear fan to suck out the hot air that the hs/f puts out, then get one, it helps.

but if your intake fan on the front is working fine and you do have a rear fan, then you shouldn't be getting those kinds of temps.

btw, you have a 63f ambient??? do you live in the arctic??

the 2 exhaust fans are working well, i can feel the air blowing with my hand. But the Powersupply fan feels considerably week compared to them. as for intake fan, there is a place where i could put another fan in... should i use it? I live by the beach in So cal so it gets pretty chilly in mornings and nights.

Not enough intake. My bro's 1.2gHz tbird with an Antec SX830 (4x80mm fans @ 7V) + Alpha PAL8045 +weak 80mm fan stays idle at 27*C. This is with an Abit KT7E. Remember that all mobos vary in their calibration to monitor CPU temps. Also keep in mind that if you do not bend up the thermistor to touch the bottom of the CPU and also apply some non-electrically conductive thermal compound to the thermistor, you will not get accurate results. No results taken with an external thermistor will ever be as accurate as an on-die thermal diode like Intel CPUs, so keep that in mind.

I must admit, i myself am pretty new at this cooling stuff, the only other thing i can think of is that you put too much thermal compound on the chip, and its inhibiting cooling, other than that, i dont know

if you're not overclocking, you definitely should not be getting those kind of temps

someone that knows a lot please help!!!!

i tried to be careful and not put too much paste on the dye.. i did what the instructions said to, rub some into the heatsink and spread a thin layer onto the cpu dye.

oh yeah, forgot to mention that you should reseat the HSF a few times. Often times newbies dont mount their HSFs right the first time, resulting in high temps because of air gaps in the thermal compound, incorrect position of clip, etc... Make sure you installed the Sk6 correctly. Some people have installed it backwards...

ok guys, here is what i think is wrong with my temperature readings. I was taking a look at my fan while it was on and i think the temperature probe is located on the fan itself, kinda in the middle where the sticker is. when i set it to blow on the heatsink, the probe is a little closer to the cpu so it gives a lower temp reading, but when i set it to suck air the probe is on top of the fan, thus being further away. but wouldn't it give a lower temp if it was away from the cpu since the cpu is what is hot?

btw the fan is a delta afb0612eh.

Am i right to think that the probe is in the fan? or is it somewhere else?

 

[FlowerMan]

LOL! That is the thermistor for the fan's auto-speed control. Those fans suck, you should consider getting a normal fan. By Delta I thought you had one of the standard Delta screamer (7kRPM 60mm) The thermistor for the CPU is in the socket, soldered to the motherboard.

Should look like this bulb type, or a ribbon type.

make sure your clip is on the right way. I've heard of people putting the clip the wrong way and managed to not crack their core.

I have almost the same setup (1040, sk-6, but on Asus board with tends to run even hotter) and had a lot of trouble getting my temps down. Several suggestions I will make have already been stated but...

First, the sk-6 wants the fan blowing. Lots of people have played with this around here and this is the consensus. The sk-6 also likes high output fans. If you don't care about noise, get a real delta.

When it comes to thermal compound, less is more. You really don't need much at all. I cover my index finger with plastic wrap and take a dab of compound about half the size of a BB on my finger and smear it thinly on the die. Any more than this and it is hurting rather than helping.

As ku said, make sure your clip is on the right way, it should be putting pressure on the chip directly over the die.

Third, get another intake fan for the case. That case has a large interior volume and only uses 80mm case fans. It needs all those fans to move enough air through that big case.

I took apart my power supply and replaced the fans with higher output ones. I didn't expect the results to be nearly as good as it turned out to be. I got a 4-5 degree improvement after replacing the fans in the power supply.

The sk-6 needs airflow!!!! You can't expect to just install a good heatsink and have it work. Even the best heatsink will give poor results if the air surrounding it is warm. You have to work on your overall airflow.
