u mentioned that northwood should not go beyond 55C. i'm using P41.8 overclocked to 1.9 only. Under heavy load, i get 58 C. So is your 55 C ment for heavy load or idle?

NoAffinity

55C is max under load. What type of cooling do you have? At the very least, I would recommend investing in some Arctic Silver 5. That will bring temps down ~5C.

I'm using intel stock cooling. at 55 C, my fan was running at ~3900rpm. i didn't know my fan could go that fast until i overclocked my P4. I thought of adding extra fans on my casing coz currently it only has one fan at the back sucking air out. my temp casing is around 45 C ( is it bad? ).
by the way, how can i change the CPU Multiplier on my albatron 865pe pro, it was grayed out in my BIOS.

What are you rooms ambient temps? A rule of thuimb is to keep case temps no more than 5 degrees more than room temp. You really need to add at least one more fan for air intake, preferably in the front or side of the case, this will drop your case temps a little. I like to have at least 2 intake and 2 exhaust.

You will not be able to change the multiplier, Intel locks this feature, unless you are lucky enough to get an engineering sample, LOL All Overclocking will have to be done by increasing the FSB (Front Side Bus).

Coz i read somewhere ( i wonder whether i read wrongly ), that lowering the Multiplier and increasing the FSB is better. anyway, i just added one small fan in front of my casing and the temp of my casing is around 39C-43C.
I drop my processor speed from 1.9 to 1.87 ( 105 to 104 ), but my temp did not drop...still around 50-55C. weird...but when i drop the FSB, i did add voltage to my ram. Will it affect the processor heat in anyway?

archer_456

An aftermarket heat sink and fan along with some AS5 will definitely drop your CPU temps down. What are your room temps? Your case temps still seem a little high. Try runnning with the side panel off to see if it helps drop the temps down. If it does, then you need more air circulation in the case. When you overclocked did you raise the Vcore any? if so how much. Also increasing the Ram voltage should not affect the CPU temps. Increasing the FSB 4-5Mhz Should not make much difference in the CPU temps either IMO. That is a very minor overclock.

I did not raise my Vcore yet coz it is still stable. All i did was increase the Vdimm. Well, i'm currently out of cash, so i'm finding solutions for a cost effective modification.
If i would increase the Vcore, my temp will surely shoot up rite? heat sinks are expensive. i read in some reviews on the net that they could overclock P41.8 to ~2.5 while using stock cooling and still maintain temp around 50C-55C which i think is quite good compared to mine.
Do u know where i can get the gel that some ppl place on top of the processor before they put the HSF on it. Will it help in cooling the chip? as in effective?

archer_456

The more you increase the Vcore the more heat that will be gerated. I don not advise increasing it until you become unstable. As for the heats, have you tried opening the side panel to see if it helps cool down everything, at least until you can get better cooling? The gel (Thermal Compound) is Arctic Silver 5 and you can get a tube of it here ---> http://www.newegg.com/app/ViewProduc...100-008&depa=0 and yes it very effective even with stock cooling.

I'll try that out...thanks for the recomendation. mayb after that, i'll push my processor higher and see how far it can go with just stock cooling.

Granted there’s a lot of info here, and it may not all make sense immediately. Don’t hesitate to ask questions, start a thread, rely on the guys that have been at it for a while. We were all newbs once, and I personally have fried more than a couple pieces of hardware (some expected, some not expected). The bottom line, have fun, keep it within the parameters outlined, and if you see something that doesn’t look right (like greatly fluctuating FSB frequency), then shut your comp down, clear CMOS and try again.

What do you mean "fluctuating FSB frequency"? and if that does happen what do you do to fix it?
