Is it better to use a higher multiplier or FSB

Hi

I want to keep my machine as quiet as possible so I was wondering... if I wanted a 3.6 speed would I be better off using 200FSB and 18 multiplier or 180FSB and 20 multiplier or does it make no difference?

FSB and multiplier wont have anything to do with your machine being noisy. Its more about the fans you use. You can have the FSB and multi as high as possible but unless you have a noisy a$$ fan, you wont hear a peep. Now if its about cooling then we are onto something.

Hi

I am using a Scythe Mini Ninja with Kama 92Mm PWM fan I have 4 case fans (Noctua 80mm) two in and two out inside a MonCaso 932 case. It will sit out in the open air in my sitting room (see spec in sig 'building') and so I need it to be as quiet as possible - it will mostly be used as a HTPC but it will also be used for gaming and video editing. I have added as much anti vibration to the case as I can (it is a fairly resonant aluminium case so it has needed quite a bit.)

I was wondering given the components I have if it made a difference to the amount of heat generated using a higher multiplier or a higher FSB so I can run fans slower.

I think a lower multi & higher fsb works the whole mobo harder which would probably result in more heat. makes sense to me anyway......doesn't make it right though.

Good thinking batman!

20 multiplier, the NB stays cooler

Less stuff to cool = quieter computer (in a roundabout sorta way)...

As mike said higher multi - less stress pc - lower volts - less heat.
Running at a higher multi may allow you to undervolts the cpu and NB (droping temps further)

Higher multi cpu's allow for the use of slower ram or fast ram at tighter timings/reduced speed

But 180x20 is slower that 200x18. (run superPi and see for yourself)
as FSB affect cpu, NB, Ram etc.

Thanks - that is really helpful. I haven't got my rig set-up yet (waiting for a left angle SATA power cable) so I can't yet test with superPI but what are we looking at percentage wise - or is it totally dependent on the rest of the configs.
