Dangers of not having the cpu fan hooked up to the mobo?

[quackerww]

Are there any dangers of not having the cpu fan hooked up to the mobo?

Some reason when it is hooked up ( to the mobo) it spins at 5000 rpm witch is very loud. I right now have it hooked up to the powersupply, its running 42-52 under load, if my reading is correct.

X2 4200
ASUS A8N5X Socket 939 NVIDIA nForce4 ATX AMD Motherboard

Can some one tell me what is a good rpm for the cpu fan I cant keep it going at max it shatters my ears. Or is there a way to set inside the bios the fan speed, I tryed but it did not work.

if you have a x2 4200, unless you have a huge heatsink with good airflow, you shouldn't run it fanless

Sorry I am not running it fanless, with most cpu fan you hook them up to the mobo, I have mine hooked up to the powersupply. Does that make sence?

It shouldn't matter. The only problem is that some BIOSes will freak out and power the system off if the fan isn't plugged into the motherboard (although with most newer motherboards you can disable this behavior).

As long as the CPU isn't getting too hot, it doesn't matter how you are powering the fan.

What do you consider to hot on a 4200?

Asus q temp program seems to work very well, higher temp higer speed.

You should be getting somewhere around ~30C maybe.
