I am not cheap, but I am lazy sometimes.

It's only two or three degrees Celsius above compared to what I had before.

You can live without case fans for a while, but consider that its winter over there, and in summer it could get much hotter. 52 is quite warm, I've never seen mine above 50.

You can probably fix the noisy fan, usually when fans make noises they just need lubricant. I did this fairly recently. Theres a tutorial here: http://forum.abit-usa.com/showthread.php?threadid=80877

52 is nothing, or at least I've never heard of anybody making it out as an "issue" temperature. My comp runs in the range of a little under 50 (at startup) to 60 (after playing intensive games), and I've never had any real problems with it doing so. I'm sure it might reduce its life by some amount by running a little over "optimal", but computer parts are normally replaced within a few years anyway.

You don't NEED case fans period. Your processor can easily operate safely up to temperatures of 70? (when it hits around 80 or 90 then things start getting damaged)

Mine sits at about 48? (~57 or so after intensive stuff)
The case fan does nothing to cool my system down, I put it in simply to have air flow so I wouldn't have to open it and clean it as often. (With no steel case around the cpu is like ~30.)

My GPU a few weeks ago had a little problem with the fan ... it wouldn't run for some reason, so it was getting up to 80, thankfully, that was the heat of the heatsync and not the actual GPU (Go conduction!)

CPUs are made to run hot. So, no worries.

UD, it's because they were all blowing in to the computer (instead of out) ... there was no airflow which made it hot, the heat couldn't escape. Nothing about "force".


Blame it on Microsoft, God does.

Thanks guys. I just need the extra reassurance from my trusty mates to feel better. I didn't think it's a problem.

Crono, something about your posts has been bothering me for a while...

It's spelled heatsink.

:P

Actually, I know exactly what I am saying. I do not really need clarification.

All my fans were blowing out thankyou, including the power supply fan (I could actually hear the power supply fan laboring to work until I turned 1/2 of them around) and with 5 of those puppies all sucking the case dry they were working against each other. So the force of the fans all working against each other were defeating the purpose. (my power supply was actually quite hot to the touch, that was the only reason I noticed, that and the fan laboring)

I would suggest that if you cannot work out every scenario possible, that you do not discount ANY as feasible. At least not when talking to me.

and before you say it. Five fans are not to many, or to few. They are just 5 fans!

I found out this morning that the whirring sound doesn't come from the side chassis fan after all. Because even with it disconnected, the sound still came on today.

So I plugged the side fan back in, and I'll just have to live with the whirr. The hard thing to figure out is that the sound doesn't come all the time, only about once every third boot.

Thanks everyone.

And UnderDog, you're right. Having all the fans sucking air out isn't the optimal setup. AMD technical papers recommend that for every intake fan, there should be an outtake one. This way a constant, balanced airflow will move through the chassis.

Its nice to have AMD support and all but it just made sense after listening to that poor power supply fan groaning so hard.

It hums along happily now. I do notice that if you listen very close that video intensive games make it alter pitch subtly as well. If I do a video stress test particularly, it actually drops several tones. <img src=" SRC="images/smiles/icon_smile.gif">

About your noise. one things for sure. Only moving parts make noise and usually its a fan so I would look there first. I had a video fan go out once. At first it was a soft whirr, but it progressed into a screech before it went. I also had a hard drive make a funny sound once. The sound was/is hard to explain but I suppose "whirr" would fit as good as any.

if you want to use an old mechanics trick you can place a drinking straw to your ear hole. The sound can only enter through the straw opening. Be careful not to bump anything as you could push the straw into the canal but move the straw around until you locate the likely origin of the noise.

That may help.

UD, the way you said it was ridiculous, that's what I was pointing out. I know what you meant and I know you knew what you were saying ... You stated it very awkwardly. How else would you know unless someone pointed it out?

How many times do I have to say I am sorry until you stop picking on my sentence structure?

Communication does work both ways. If you did, as you say, understand, why are you picking on me about it?

So I used nomenclature that was detrimental to the workings know as "force". <img src=" SRC="images/smiles/sad.gif">

Heh, I am a doctor. I don't need the straw. <img src=" SRC="images/smiles/icon_smile.gif"> I already used my $400 stethoscope to listen to every fan in my case previously. Because the problem only happens intermittently, I have never catch it when it occurs.

But once the noise stops completely, I'll get worried then (the fan probably stopped turning finally). So far, whenever I open my case, all the fans are working properly (when I use an otoscope to check and a stethoscope to listen).

I never thought my medical equipment would be so useful when it comes to diagnosing computer problems.

I suspect it's the GPU fan that's making the noise. A few other Radeon 9800 Pro customers have had this problem too, but it's nothing serious.

Trying to contact ATI is such a pain in the butt that I gave up after half an hour.

Any video card fan will die sooner or later. A drop of oil, or dry lube if you can find it does wonders for a noisy GPU fan. I already posted the tutorial, so if it keeps bothering you, you know what to do. I'm sure theres some pretty nifty medical equipment you can use for this purpose <img src=" SRC="images/smiles/icon_wink.gif">

I figured out the problem finally. It was the GPU fan that's making the noise.

I vacuumed the inside of the computer thoroughly, and used a Q-tip to clean out the scum on the fan blades. The whirring nosie is gone now.

Thanks.

Wierd, I was gunna say its most likely the north bridge fan, they are notoriously loud on startup. Least you found the problem!
