Turn off my HSF's fan when CPU @ Idle?

[MillhouseOfHorror]

My HSF is'nt loud, but when Im trying to sleep, its enough to bug me.
Im using THIS HSF (HHC-001), and was wondering if it sounded like a really bad idea to wire the fan up to my baybus and turn it off when the CPU went to idle.

Seem smart, or is my CPU destined to die a fiery death?

meh, at least it would be an excuse to get a 1.6a

edit:

forgot to mention that Im running an XP 1700+. temp w/ fan on @ idle ~ 32C.

 

[MillhouseOfHorror]

currently running w/o fan running. Im at 43degrees C after about 5 minutes of running. Im hoping that its topped out.

If it stays here, Id be happy to run w/o fan at idle...

this would be a good time to use that VIA HALT mod...good thing Im running a 266a

turned off my northbridge fan and the temp jumped to 53 .

Seem like a descent temp, or is this something I really shouldnt be doing?

 

[Bowen]

I wouldn't do that if I were you. What if something happens and your computer decides to do something thereby bringing the temp. I have almost no TSR's myself but I would not want to take a chance my CPU burning up ya know. That's just me and you may be just fine but I would rather be safe than sorry. Just turn you computer off at night.

Cant you just undervolt the fan, run it at 7v.

See if u can get a hand on those voltage adjuster to lower the voltage on ur fan to slow the fan down. Frankly, I wouldn't wanna off the HSF completely.

If ur mobo supports STR...use it.

Just buy a quieter fan.

If your mobo is supported, Speedfan is a software utility that will vary the rpm of your fans based on temp readings. This is the way all systems should work. I cant understand why cooling fans operate at a fixed rpm in modern day PC's.

On account of they cost fiddy cents to make and the variable ones cost fiddy one. Or something like that.

I suspect an aluminum heatsink would be more suited to what you want to do. The compact copper ones would tend to store heat with the absence of adequate airflow.

Still, throw in a large Papst sintec and run it at the lowest RPM necessary to pass enough air through the case. Blowing hot air around inside the case is counter-productive.

 

[oldfart]

It costs nothing. It will work with any fan. Many chipsets have support built in. The only thing needed is some simple software like Speedfan to vary the voltage going to the fans. I'm using it right now and it didn't cost me a dime.

 

[Auric]

Yeah I know and I agree Speedfan is a Good Thing (TM). But I mean hardware solutions like a thermal variable fan cost more so PC companies are generally not going to use them. Software solutions even if only an interface to hardware means more potential problems and hand-holding. It is up to the individual to tailor the shoddy mass-market disposable PC to their own environment and use.

I have the same problem with my noisy delta fan, what I do is to make it work at 7V and it just goes from 39C to 44C and the noise is almost completely gone. Just connect the ground wire of your fan to the 5v signal (Red wire).
