Processor hotter as you Raise FSB and lower mult.?

I'm looking to improve the performance of my comp a little, but right now my Heat sink blows (which you know if you've read my post in the cooling forum). Anyway, I was wondering if I could raise my FSB and back off on the multiplier so that I end up pretty close to the rated speed of my 2700+ (200 *10.5 or something) without raising the temperatures more than a degree or two.

I am running a 2700+ on a A7N8X-dx with Golden Dragon pc3200 ram.

If your cpu speed ends up being the same or very near to default then it won't make any difference to cpu temps:)

Voltage raises the temps more them fsb does. If you dont raise the default on the CPU then it shouldnt get any hotter. If you can raise the FSB and leave the voltage alone you should be fine.

Raising the FSB will make the northbridge get hotter, which could slightly increase case temps.

On my A7N8X Deluxe, I have a 70mm fan that hangs over the ends of my SK-7 CPU heatsink, and blows onto the northbridge heatsink, so that helps keep it cool, which is probably why I've been able to run perfectly stable at a 230 Mhz FSB before... can't find a happy spot for my RAM at that high a FSB though, so I leave it at 200.

I assume that since my mobo is revision 2 and says on the box, "400mzh FSB ready" and "nForce2 400" that having the FSB at 200mhz won't overheat the NB, so that shouldn't be a problem unless I start going above 200mhz.

Does that Zalman keep the NB much cooler than the stock heatsink? Is it hard to take off the stock one and add the Zalman? What is a reasonble FSB that I can expect to be stable on this board with and without an after market cooler like the Zalman.

yup, which in turn raises cpu temps

True ,but by a very small amount

yes i too, whould like to, know is the zlaman better then the a7n8x motherboard's stock cooler, if so by how much?

ok, do you really need an after market heat sink or a cooler for a board that was designed specifically to handle a FSB of 333 or higher?... these boards are build and tested to withstand a processor with such a high FSB.

I dont know why people worry about the chipset getting hot the CPU is the most important part to worry about.

But for those that want to see something neat check out a Zalman repalcing a stock heatsink and watch the temps go UP lol.

Depends how hot it gets ,if its within the 'tolerance range' & your not going for overclocked FSB then it won't make any difference

signal integrity could be more of an issue than heat
