I have just picked up a brand new unboxed P4 2.8ghz (SL6PF) northwood for my P4PE based system. It was going cheap and i could not resist (Â£28)
I originally had a P4 1.8A and managed to overclock it comfortably to just under 2.4ghz, by upping the FSB to132. I fitted a Zalman CNPS7000 Alu/cu to keep the noise down and with the fan running at 2000 rpm, i had idle of 43 and full load of 52Â°C, even in a warm bedroom.
No stability issues whatsoever.
Since fitting the new processor, i now have idle of 49 and load can go as high as 63Â°C even with the Zalman fan cranked all the way up. I have re-seated the heatsink a few times just to be sure, although i am using a thremaltake â€œpremiumâ€ silver paste as i have no AS5.
mobo temp is 35 to 38Â°C
Again, no stability issues.
Although its summer, i still think the temps are a little high for a northwood.
Do you agree?
I am sure i can squeeze more out of the cpu, as it will be a while before i can upgrade to a quicker system etc. Just trying to get the most out of my eqpt whilst keeping the noise down.
Temps are read via Sandra or Asus Probe.
I do like a quiet PC and have considered swapping my current HSF for a Thermalright XP-90. Would this perform better than the zalman, even at low revs?
Thanks in advance.
