cpu tempreture is at 58C now

[sys14]

I bought a new cpu heatsink and fan. I ran the pc without the cover, the temperature is quite good : 51C. But when i put the cover on, and make the tower stands up, the temperature increased to 62C!! now i took out the cover again, but still let it stand. The temerature drops to 58 degree.

Is it good enough? i've got 2 case's fans already. One at front, one at the back. And the new heatsink works pretty good as well.

im using athlon xp 1800+. Is it possible to cool it down more? or is it the CPU's problem?

Well we'll need a little bit more information on your system.

What type of Case do you have and what type of Thermal paste are you using? What type of CPU fan are you using?

One thing to make sure is that the case fans aren't causing turbulence. It's better to have low CFm(cubic feet per minute) and good air flow like a tunnel effect than something with high CFm and lots of turbulance.

You want to create a wind tunnel effect with your case fans and then make sure that you have "Arctic Silver III" thermal paste for the CPU and I would highly reccomend getting a ThermalTake Volcano 7+. It's by far the best CPU heatsink/fan and is under 20 bucks.

If your still experiences really high heat you might want to try rigging a connection from your air conditioning vent and some tubes to your intake fan on your computer. If the air isn't cold enough and won't cause condensation, it would cool your computer down alot!

thank you very much!
my system: athlon xp 1800+ asus A7V333, using a taiwan brand HSF, pretty heavy (380g), in copper, and quite a big fan. I used the thermal paste which came with the HSF, it is white, not silver. I counldn't find "arctic silver 3" in the market (i am in Hongkong).

I am not very experienced in assembling modern PC, before, i've never spent much time on putting cpu onto the motherboard, pentium, pII, athlon, celeron, they were all very easy. Now, there are huge fan, thermal paste, heavy heatsink. And very hard to install.

It's quite cool in my room, only 24-26C. is there any possibility it's cpu's or matherboard's problem? If no, i will try my best to find a way to cool it down, maybe buy a taller case?

The problem could be the design they put where the case fans go, most are awful and block too much air so it's better to cut them out. Also with the better airflow you get more silent fans, just remove everything from the case before cutting the holes.

I'll take pictures of my hole cutting, but I'll have the pictures in about 2 weeks. (I take pictures all the time in case I need it to show somebody something. )

Just wondering but what heatsink is it and what fan did you put on it?

[sys14]

it's a taiwan brand heatsink with fan. pretty heavy, copper, big fan. I replaced my origin athlon xp HSF with it. I thought it's pretty good.

 

[bum_jcrules]

What brand? Or is it in Taiwanese characters? It should have some form of English writing on it or at least on the box.

Is the company name Taiwan?

Yes, it's in chinese. Can't find english name on it :~

looks alrite, it's copper plus gold plated. are you sure you didn't put on the hsf backward?

just a thought...
on the bottom, is it flat? because in that one picture, the right one on the top...
it looks like the middle has an indentation. like the surrounding is supposed to be like a shim. i am guessing that because the glint of the metal in the picture. or it might just be some camera glitch...i dont know.
but if that is the case, then maybe it is because the ridge is sitting on the rubber pads, and causing poor contact.
i dont know for sure. maybe there are installation instructions?
also, make sure that you put the heatsink on right, because if it is on backwards, then it wont work right...

I think so too. The rubber pads are supposed to create the right amount of tension on the heatsink so that it doesn't crush the core but the shape of the heatsink may not provide close enough contact.

Another thing, did you apply too much thermal paste? If there is too much that will decrease thermal performance.

In regards to your two case fan locations (assuming the front fan is your intake and the rear fan your exhaust):

Which of the two locations is higher up the case (when the case is standing up)? Every now and then, the exhaust location will be lower than the intake location, and this is not desirable. A variant of Archimedes' Principle of Bouyancy dictates that the warmer air will rise, and if the exhaust location is lower than the intake, then the hot air will turbulently circulate at the top of the case, which inevitable destroys attempts at proper temperature control.

The previous poster discussing turbulent airflow throughout the length of the case has a good point. Turbulent airflow will cause the CPU to settle at a higher-than-expected equilibrium temperature than a laminar airflow situation would produce. Make sure the air intake fan is clear from undesirable obstruction, and you may want to pay attention to where the intake is relative to the CPU. The natural air flow pattern through the case may not produce appreciable flow over the CPU, and these airflow patterns will certainly vary depending on the orientation of your case (standing up vs. lying down).

Just my $0.02.
