Processor Temp: P4 3.2 GHz HT Northwood

di11on

Hi,

I've just built a system with a Pentium 3.2 GHz Processor with HT (Northwood I think).

The idle temperature is around 45-50 degrees and the full load temp maxes out at around 64. Does this sound ok?

The case isn't designed for more fans, so I'd have to get a new CPU cooler or something.

Would appreciate comments.

Thanks

Sounds about right, get a new HSF n the temps will come down a bit...

di11on

Thanks... that's encouraging.

Gonna replace the termal interface material that was pre-applied to the stock heatsink/fan and apply some thermal paste instead. Should help reduce temps a little.

Bumpety bump -

Could someone perhaps tell me what sort of temps they're seeing with their P4 3.2 GHz?

Thanks

prescott 35 degrees with Zalaman CNPS9500-LED

o'ckd to 3.8 - 40 degrees oc'd idle temps

idlin about 35
heavy usage 50ish with intel stk
but thats on 3.4 lga775 ,
one thing dont forget to clean between the fan and heatsink , i got a drop of 30 degrees by doing it

Man...

I took the heatsink/fan off my 775 P4 3.2 GHz - removed the pre-applied thermal interface material - cleaned both heatsink and processor thoroughly - applied thermal grease and my temps went up!!??!!

I find that very surprising because when I took the heatsink off I saw that the TIM wasn't even convering the whole surface of the heatsink or processor - so I'm very surprised I'm not seeing a reduction.

Anyone got any theories/suggestions? I'm hitting 65-67 degrees when playing games... surely that's not good?!?

I find the 775 socket heatsink/fan locking mechanism very fiddly. You have to press down really hard to get the locking pins to click - I'm afraid of damaging the motherboard!

Excalibur: What sort of case do you have? How many fans?

Thanks

You may have left some air pockets between the heatsink, the thermal material and the processor. this may acount for the rise in temp you notice. i'd suggest applying as thin as possible with a credit card. also don't discount the effect dust has on retaining heat.

get a Zalman heatsync and fook out your old one in the bin its worth it !!

How are you measuring the temp? What motherboard are you using? It may be reporting an incorrect temp.

Motherboard monitor will give you correct temps.

Ive a P4 2.8 Northwood overclocked to 3.2 with the Zalman cooler.Temps @ idle are 24-25.
Under load they hit about 35-40.
Before the Zalman they were 45-50 idle and 60-65 load.

there you go Zalman is the way forward !!

di11on

Hmmm... Zalman sounds like the way to go...

Hellrazer: What Zalman heatsink/fan you using? Is it noisy?

I think I'll try reapplying the termal paste, and if that doesn't work, I'll get a Zalman...

Should I apply the paste to the Processor or heatsink or both?

When you say apply with a credit card... how do you mean? Should the entire surface be covered? Should I be abke to see the serial number on the processor?

Thanks

Zalman CNPS 7000B Cu is the one I got.All Copper.Its quiet enough but there are 3 fan speed settings.I have it on the Fastest for best cooling so it is noticeable.

Drapper

did you ever get sorted and hows it now?

BigEejit

I found before that using too much paste will increase temps ... a really thin film is what should be used ... it also depends a lot on the paste you have, artic silver is the canines dangly bits

They are typical temperatures for that CPU with the cooling you have. If you want to overclock, you'll have to improve those temperatures by 1) getting better fans(i.e. higher CFM) 2) better heatsink(e.g. Thermalright SP-94) and Artic Silver 5 thermal paste

Zalman knocks the socks off the Thermalright ! ;-)
