Sound Insulation for my Computer!?

[ShadowTek]

Actually, the stock fan that came with my Core Duo E7500 is very quite, even at full speed, but the retention mechanism is a pitiful joke, so I wouldn't recommend using it.

[Tony Hwang]

Hmmm Some PC case has fan speed adjustable. They being running at 12V DC You can slow them down by running at 5 or 7.5V(between 12 and 5 Volts) Or using series resistor of proper Wattage or Rheostat.

If your going to do that, I'd suggest cutting the entire back out of it. Then, you could leave the front closed. That's what I did for a while, and my system never got hot.

The heat being generated by the CPU is a function of the workload the computer is doing. If all you're doing is word processing, the CPU isn't putting out much heat and the fans can be slower (and perhaps one of them can even be shut off). If you're doing heavy video games, the CPU can run real hot and the fans need to be fast--or else the CPU will overheat.

To control the fan speed interactively like this, he can purchase a fan controller. This is a panel with controls that adjust rheostats that in turn control the speeds of the various fans. That way, he can make a precise tradeoff between fan speed and noise--he can lower the fan speed just enough to reduce noise, while still moving enough air to keep everything cool.

As many of those things as you can, plus what fan speeds you can. The software will look for things it can monitor. In my case, it finds the CPU and the motherboard. I don't know where the sensors are and I don't need to know.

My computer mobo runs at about 85F and my cpu at 150F. The software, Asus Probe, will make a beeping audible alert if it gets too hot. The volume is adjustable, and I tested it and even 1 (out of 10) is noticeable if I'm sitting in front of the computer)

It also monitors 4 voltages and up to 3 fan speeds, although in my case, it only monitors the CPU fan. The Power Supply fan isn't set up for that, and I have an added fan but it's connected straight to the power supply and not through the motherboard. There is a little

1x1x3/8" fan on a chip, but that fan doesn't get monitored. So the setting to monitor the chassis fan isn't used.

If any monitored fan speeds goes below 600, or any voltage is 10% low (or high?) or if the temp goes over 122 or 167C respectively, the alert starts to beep.

I can change each alert threshhold separately. Maybe I'll look for more info about temperatures and do that. (I've only been using this reguarly since my power supply failed last week.)

No need unless your computer is very old.

I tried SpeedFan when I read about it here and it was not at all obvious. I'd call it obscure. I'm not interested in lowering fan speeds so I went back to AsusProbe. (If I were interested in lowering fan speeds, I woudl disconnect the fan I put in front of the case, which does nothing since neither side is on the case. They're supposed to be, because the entry at the lower front and discharge at the upper rear makes an air current that goes over all the hot parts, but I've been running like this for several years so I guess my particular parts aren't going to overheat.

I did look at the part that checks the hard disk and it said mine was fine and had never had problems. I hope to use it occasionally to see if it stays that way.

12 - 5 = 7.5. New math?

[marco polo]

mm,

under System it says Manufacturer: ASUSTek Computer Inc Model: ASUS Computer Series Processor: AMD Athlon 64 dual core etc etc

Well anyway, it looked [to me] like I had an Asus motherboard, so I tried to install Asus Probe, but it said "...you need a Asus Motherboard.."' So I guess maybe I don''t have an Asus

It doesn't say that; it says runnning at BETWEEN 5 and 12 Volts, 5 and 7.5 being two of the choices used, which is common for some of the older multi-speed fan managements. More often in newer machines they're driven by a variable pulse application so that heat dissipation in components other than the fan are not an issue of any sort.

Before I get flamed; Just noticed the incorrect nic and fixed it. Stoopid OE!

While refusing to admit the ambiguity in words. My definition is just as valid as yours. It's simpler to achieve. You already (in a PC) have

+5V and +12V lines. connecting between them gives you 7V. The other sort of 'between' is more complicated to achieve.
