*Another P4P800 WOW*

[XJ.]

Geez and 80cfm Delta - I'd go deaf! Thank God I have water cooling

[pitzuchim]

Hmm... do you think it would be necessary to get a fan for my northbridge on the P4P800-Deluxe? If so, what fan should I get, and how do they mount?

[Skully]

I have a 120mm fan blowing on my NB. It makes a big difference. Before fan 95-96f after 82-84f!

Are you deaf? Does someone constantly vaccuum the floor right next to you? Do you live next to a railroad track with an infinitely long train driving full speed on it? If you answered no to all of these... how can you stand the noise of such a massive, massive fan?

Hehehe ok so anyway... how do I know WHICH fan to get, and how do I mount it? Does not having a fan on the northbridge mean I can't reach as high an FSB?

120mm fans are not necessarily noisy. Additionally, they produce a lower frequency hum, and are thus less annoying. I have a Panaflow 120mm that produces 70cfm at 30dbA - not bad at all

Thanks buddy, your quite right! My 120mm is a Panaflow fan.

My setup may not be for everyone, as I run my case with the side panel off. This is because I run an outside the case water rig. Cooling the NB down will usually let you oc a little more with stability.

Does cooling the NB generally make it so you can go higher with the FSB, or higher with the CPU speed? I know these two are linked, but maybe a cooled NB will let you go 250 FSB at 5:4 but not 250 FSB at 1:1, etc

It should allow higher fsb in any ratio. Not a lot but some, if nothing else you gain stability.

more stability than higher fsb in most cases

When switching from 250mhz 5:4 to 1:1 NB may not be the limiting factor here. It's your mem.

[Skully]

Also try keeping the memory cool. The same 120mm fan I have blowing on the NB also blows on the memory. My memory on the IC7 was getting quite warm to the touch. After applying the fan, much cooler to the touch.

[pitzuchim]

Yeah I know the problem is with the mem right now. That was a hypothetical example. Anyway... I think I'll just stick to casual overclocking. I don't want my system to be too loud, anyway.

I hear that!

So far I am happy with the P4P800. The 2.6C is running at 3.2 gigs now at 1.575 vcore 5:4. I installed a Zalman 7000ALCU tonight with Ceramique and the temps went down 4C so far at idle to 31C. I expect that to drop a tad after the Ceramique settles in.

The Northbridge ran hot so I pulled it off and found the hs paste Asus used was only about half on. Some repair there and back on after slicing the foam pad a tad to allow my temp probe ifurther in.
I also installed a fan from a Thermaltake Blue Orb. That is hooked up to my new Vantec Rheobus so I know it makes a difference and the temps dropped about another 4C.
Kinda matches the Zalman 92mm too. Not ideal but will do for now. Seems the Zalman helps get ait to the ram but I would like to get more air into that corner.

The OCZ3700Gold I have is holding me back at 1:1 at 233mhz and above. Memtest returned errors so it looks like an RMA will take care of that.

When that is resolved I will see how far the 2.6C will go.
