I may need to re-think my fan layout

[DaJe]

I have 5 fans cooling my case (and one on my hard drive). One exhaust on the back, one exhaust on the top, one intake on the front, one intake on the side, and one exhaust on the side. I just shut off 3 fans, the one in the back and the two on the side. After that, I kept a close eye on all my temperatures. My computer did not warm up at all by having the 3 fans off. Any ideas for what I should do? Maybe remove some? Maybe I should make both on the side exhaust.

How long were you watching the temps? Was your CPU or Graphics card under load? If so, how much of a load? Are you O/C'd?

[DaJe]

Not really any heavy load, and I'm not overclocked. I watched them for about 30 minutes.

You might want to check the temps under a decent load with the fans, and see if/how much the base idle temp raises. If its minimal or none at all try it without the fans.

I'd have to agree with ozzmossis66, try putting your computer under a stress test in both situations and see what the difference is.

[DaJe]

I get what you're saying. There's a certain point where adding or removing fans won't do anything, or at least less fans are needed and adding more won't make a difference. But if there's a build-up of heat, that's when they'll work. I'll go run the Nvidia stress test.

Here's the whole computer being stressed, with those 3 fans off.

Here's just the processor being stressed, with those 3 fans off.

121C?! You MAY want to clean up the dust in your computer. Just with that temp, if it's your CPU, it should've died (or will soon). Where's going that probe?

Actually, if you're not overclocked, there's no need for 5 fans. My current Athlon has 2 exhaust in the rear and one intake in the side (i would have one in the front, but I need to make some holes in the front bezel.. cough-modding-cough :)), and I wouldn't imagine having all of them off right now, but it could live on stock settings with only a side intake.

[DaJe]

That 121 isn't an actual reading of anything. I'm not sure what Speed03 is, if anything. But when I set it to 100%, that temperature automatically goes to 121. And if I set it to 0%, it goes to -48


Oh, and Temp2 is my processor, and Temp1 is my motherboard.

[rendermandan]

you should rename those in speed fan so its easier to tell what is what. -Same for your fans as well. (2 cpu fans?)

I have the same problem with Temp 3. Mine reads -37c at times and after tweeking the probe type in the settings it now reads 25c-26c but again, I have no clue what it is.

Daje, please post in the proper forums.

And on another SpeedFan related note, I just did a S.M.A.R.T. analisys of my hard drive.


NOTE : your hard disk Power On Hours Count attribute current value (96) is below the normal range (99 - 100) reported for your specific hard disk model. Basically your hard disk was powered on for more than the maximum time the average user did. This means that either all of the reports collected are from hard disks that were not powered on for too long (this is realistic for recent models) or that your hard disk is becoming old. Usually this is not considered as a pre-failure advisory, but you should check whether you want to replace the hardware or keep an eye on its performances over time.

The overall fitness for this drive is 90%.
The overall performance for this drive is 98%.



Soo, about that power on hours thing. Is that bad thing? I keep my computer on 24/7. Think that's why it tells me that?

[Nagoshi]

If you leave your comp 24/7 because you can't wait the 2 minute load when you push the power button, you've got a problem somewhere. If you can turn it off during night, do it (unless you are downloading stuff, or housing a game server, burning overnight, stress-testing, or etc). Keeping on just makes more noise, burns power, shortens your components life, and you are more aware to power failures, and there is no sens in keeping it powered when it's idling overnight.

Besides, keeping a computer 24/7 without shutting it down ends up by filling the memory (physical, cache and pagefile) and slowing the computer. Not really noticeable in nowadays' computers, but take an old Pentium3, keep it 24/7 on and stress it, for like, 8 hours a day, performances will be slowing down after 1 day.

36c for your motherboard ouch...mine runs arround 25c & processor 32c and HDD 36c.
Ive got a 120mm in front 120mm back ,And another 120mm on the side just below the graphics card and a 80mm on the top.
