Well i bought an afterstock cpu fan which is this one
http://www.newegg.com/Product/Product.aspx?Item=N82E16835185125
and I installed it but it isnt really helping with my cpu temperature, its goes up to 32 degrees C just by starting TF2 or CSS. Idk if it takes time to get data to actually cool it down or if it the problem that I only have one fan blowing in and thats on the other side of the computer.
I know a person that overclocked it 500 MHz and is idle at 19 degrees C so i was wondering if I could get some help
 
well, first off there's nothing at all wrong with running at 32 C. that's a really good temp for a loaded CPU. the fan you bought is most likely not going to drop the temp on your CPU all that much from the stock fan - it's an ok fan but it's nothing spectacular. that's why it's only $30. also your CPU is a big factor...what are you running, and how much are you overclocking it?

if you're really worried about it try removing everything, cleaning off the heat sink and CPU and re-applying your thermal paste...maybe there are some issues there.

also remember that your temps won't level out until a good 72 hours after new thermal paste is installed...it takes a while for it all to settle.

so - my suggestion is just leave it - really 32C under load is a good temp. oh - and i'm not sure about your friend, but i doubt you're going to often see temps under 20C with air cooling, even at idle.
 
It could be a number of things.
1. Did you evenly tighten all the screws down when you install it.
2. What thermal paste did you put on your processor and did you apply a thin even layer of it on the processor?
3. Does your case have good airflow?
4. Did the temperature drop at all after installing your new cooler?

just keep in mind 32C inst a bad temp at all if thats under load.

my cpu at idle is still at like 22C. At full load it will go up to about 45C.

O my cpu is running at 2.7 GHz it this cpu

and this is my thermal grease

well im planning to overclock it like my buddy to up to 3.2 GHz from 2.7
and my case is ok cooling becasue i have a fan sucking out the air right when it blows out but I only have one fan blowing in and its on the other side
and the thermal grease that i put on, my dad did it and he used a hell of a lot of thermal grease, not just a dap but like 6 daps.

that may be part of your problem right there. you only need a very small amount of thermal paste - most professionals will tell you to place an amount the size of a pea in the center, place the heatsink down firmly and then allow the thermal paste to settle. the other option is to VERY CAREFULLY spread a thin layer over the processor, but you need to really watch doing it this way.

also remember that overclocking is going to run the temps up on your machine, so don't expect your temps to stay REALLY low at load with air cooling alone. the setup of your case is extremely important - you need at least one intake fan and two exhaust fans if you want to see some good airflow, and you need to make sure your cable management is decent. cables all over the place impede the airflow and will not allow everything to cool properly.

also remember that the size of your case makes a difference as well. a small case isn't going to cool as well as a larger one simply because all of the components are closer together.
 
If you are still getting high temps after you re-apply the thermal paste you could try bumping up the fan speed a little, if you don't mind the extra noise.
 
Also Arctic Silver 5 has a 'burn in time'
 
Yea as trykael said, re-apply the thermal paste. I would reccomend just a dab and spread it out thinly with a creditcard or something of the sort. When you put your cpu cooler on make sure you get it on the cpu evenly so that it dissipates heat correctly.
 
32 C is plenty cool for a CPU, especially 2.7 OC'd to 3.2. You don't appear to have a problem.

thats a great temperature i wouldn't be worried if i was you...

but if you want you could try re-applying the thermal paste... just remember to have a very thin and even layer.

Im the friend.....
my rig runs idle 14c.under full load nothing over 22 c...on air.
with the same fan and cpu..
choas your dad put way to much on..
like I said,a small amount and use a playing card and level it out over the cpu like your painting it..
stock fan was idle 23c,14c with A/C..
stock fans are junk.................
 
14C is 57 farenheit. That's cooler than room temperature, unless you keep your house really cold. I wouldn't buy a temp reported at 14C as accurate on air cooling, because it's not really possible for an air cooled CPU to be colder than the ambient temperature. Probably misreported by the temp monitor.
32C is a great temp for a loaded CPU. I wouldn't worry about it. Just test and monitor after OCing (I use HyperPi, but there are other ways out there). OC in steps, not all at once, and then run it through an hour or so of 100% load while watching the temps (again, hyperpi works great for this).

yes it is 57 .and no I dont keep my house freezing 73 are the temps in my house...
and heres a screenie for ppl that say no.useing HWmonitor..
15 is now...14 is idle and max i have seen running CPU burnin 2x for both cores 22c tops running for hours....and it dont matter what temp monitor I use its all the same temps.

Your HWmonitor is jacked. No way can the CPU run at less than room temp with just air cooling. Unless, of course, you think the CPU has somehow defied the laws of physics. Guess the experts all missed that one :P
 
i wouldn't always trust a program like that for temp details the best way is to look at it in the bios. :)
 
What CPU?

Also, your temps depend on your ambient temperature (IE, the temperature of the room). Unless the guy you were referring to lived in Michigan, I doubt he has a 19*c core temperature. I've got a watercooled quad with a 120x3 radiator, and I can only get down to 22*c or so (though my deltaT is much lower than any air cooler would be able to match...).

~Gooda~
 
Think of it this way. If your CPU is somehow lower than room temp, the air being pulled across the cooler by the fan is actually warmer than the processor. This means that the air cooling will actually be WARMING the processor. This is the law of heat exchange. Because metal is a poor insulator, it is possible for the processor to be cooler than current room temperature, if at some point the room was cooler than it is now (like if you turn down your heater at night), but when you turn it on, it heats up due to it's own internal energy, and the fan will pull the warmer air across it, bringing it to at least ambient temperature, because physics states that it will try to reach parity with the ambient temperature. This is also why air cooling works, because the heat generated by the processor dissipates into the air as it attempts to reach equilibrium with the the environment. So it is actually, short of using nitrogen or some other cooling agent (not water cooling, that doesn't change ambient temp, just changes the heat dispersing properties of the substance used to dissipate heat), impossible to have a CPU temp lower than ambient temp.
