- I have a 60mm and it's about as wide as the heatsink. 80mm probably too big.
Don't try and spot cool it from a distance. Most 80mm are so low CFM... the airflow would get lost in the cross section of the case, well, at least it would in my windtunnel. lol.
Stick to 30/40/60 that you can fit RIGHT on the heatsink, as to get the airflow going right to it.

I replaced the NB hsf with an HR-05.
I added 2 chrome plated copper heatspreaders on the RAM sticks.
Added Thermaltake CL-C0025 copper ram heatsinks on the MOSFETs
I spent most of the day yesterday playing with it and oc'ing. I'm running pretty stable at 390 FSB x8 multiplier, 1.4 vcore, 1.56 vnb, 2.08 vdimm and 910MHz 4-4-4-12 at 2.08 vdimm (yeah, those Elpida chips surprised me too, especially since i paid 38 pounds for the sticks). Bios is 0401.
However, that's about the highest I could get stable. It looks like I can't get over 3.16 GHz on this CPU no matter what I try. I tried x9 multiplier and lower FSB, no luck. Any FSB above 390-395 will not even post and any combination of FSB and multiplier resulting in a freq above 3.16 GHz will not post either.
I followed many guied and tips for this mobo (including the one at anandtech), tried raising the voltages (reached max voltages), lowered dimm timings, etc. The above two limitations seem to be omnipresent no matter what I do.
If anyone thinks I'm missing something, please let me know. If not, is the above 395 FSB limitation be caused by the mobo or the cpu? The 3.16 GHz one is clearly the CPU I believe.
Anyhow, 3.12 GHz is fine by me on this CPU but I would have liked to use a higher FSB.
p.s. I am for now testing this mobo and will have a chance of getting a P5K instead (not deluxe or -e, the bare p5k). Anyone knows how the P5K compares to the P5N-E in terms of stability at high overclocks?
OK- first off, did you set your RAM timings/vdimm manually?
Second- what BIOS are you on?
OK now, I believe the stock multi (9x) is your safest bet.
Start from stock at the 9x. Remember, the 4300 is the lowest C2D, don't expect it to do 4Ghz. I know a lot of people have tried volt modding etc (madmax) to get it over 4Ghz. I am not sure at what point he had to do that, I don't even know what a NORMAL acceptable OC for a 4300 is.
I know they have trouble with higher FSB, so stick with the 9x.
The other main thing I noticed: why are you running 390 FSB and 910RAM?
Stability for Intel = 1:1. ie 390 FSB, you should run your RAM @ 390. (ie DDR2-780)
Remember, our BIOS displays effective values, so for 390 1:1 you'd need 1560 FSB and 780 RAM. But- remember the 4300 doesn't like higher FSB (from what I've heard) So maybe try 9x multi and lower FSB, with manual timings/vdimm and 1:1.
Start with 350FSB x9 = 3.15Ghz (DDR2-700 in BIOS, FSB = 1400)
I think you should be rock solid stable with that - as long as your timings and vdimm are good to go!
Also note- SYNC mode is 1:1, or you can just use full manual and type them in yourself (which I prefer)
Oh, and have vcore set to, I'd say 1.4v, but I could be wrong (I don't have a C2D!) But I think 1.4v is safe for you, and should allow you to hit 350x9 easy.
And remember, you have a northbridge voltage (MCP) you can adjust. 1.3xx and 1.5xx are good, 1.7xx is probably not neccessary with a 4300, if it's really neccessary at all (hah... Pook...
Oh, and add your system specs, and welcome to OCN & the P5N-E Club!

I have a confession. I took the easy route and put the 4 extra RAMsinks I had on my SB.
I shall take any punishment Pook and pawl see fit for me.
Atleast I'm ready for that second 7600GT now.
Something I saw, which I did not predict. I'll only have one open PCI slot.
I already have a TV card in one. So if I get a sound card, bye bye TV card. :'(
PS. The RAM sinks don't look bad, they are a bit skew, but who's looking anyway?
RAMSinks, nice. SLI 7600 before me? I hate you
Are your 7600's huge, because mine aren't. lol. I can't believe you lose those slots... ?
