Cards touching on cusl-2c?

I've just stuck a powerpulsar in my machine, slot 1, and put the pulsar 1 in slot 5, all is working well.

But the agp (nvidia riva tnt2 model 64) graphics card's fan is just touching the front edge of a DSP on the powerpulsar (perhaps 1mm by 17mm area).

Is this really bad?
Should i turn my machine off immediately and thank my lucky stars i didn't fry anything, or just act casual & rock on regardless?

anyone?

the fans are usually plastic, so no harm to expect.
It's important that the cooler metal doesn't touch any contacts of the DSP (or other parts with electric activity).
Keep rocking

cheers, Tom

Phew! Thanks Tom

Anyway I would change the situation for a couple of reasons:

1) A contact with a rotating thing will obviously generate vibrations, I'm not sure that in a long term this is good for hardware's life. I would consider the example of the water drop, that is appearently unable to harm a rock, but you find a hole after a year...

2)I'm not sure that a fan will do it's job by pulling heat from a device to another one..

If your problem is IRQ, the important thing is that the card acting as the main one, thus monopolizing crucial pci tasks has an independent one, while the other could also be assigned to a shared one..

My advice is to move the card...

Cheers

As a former HiFi geek, I can tell you, that vibration is something that nerds want AWAY from the equipment - also *nonmoving" stuff like amplifiers (it all moves to make sound - we just don't see it).

I would definetely search for a way... vibration is a problem, I join that others have said about it. Components are extremely small, you have to realise that this vibrations even so small, may cause damage in the long run.

Perhaps you could sand very gently the plastic, till it does not touch any more, of course, if your video card is out of guaranty, because this would straight void your guaranty.

I agree with Alfonso as it would disturb me too - it is simply not the proper way that the parts touch - but for me that's an emotional issue only.

There is so much stuff vibrating in a PC that it doesn't matter if a little bit is added, specially if it's at such a low frequency as a rotating fan.

HDs, the other fans, CD and DVD drives and then the 'unhearables' that Immanuel mentions.
Allmost all parts of a circuit board are vibrating someway and the ultrasonic effects probably have an even more severe influence (more movements per time). Don't panic

cheers, Tom

Well, I didn't think this way, but reflecting, you are right Tom. Nevertheless, it all depends on the way it vibratest too, if vibration is minimal, ok, otherwise...
